Street maps. OpenStreetMap Project Maps

2) Vectors available in editors and for download as files

For orientation on the terrain, maps must be loaded into the device with which you will go to this terrain - capable of receiving a GPS signal, drawing a map and your position on it. If the device can still plot a route, it's generally good.

Today we will talk about converting OpenStreetMap maps for displaying them in Russa or Navitel Navigator programs. Accordingly, these maps can be loaded into devices where one of these programs is running.

Generally speaking, you can download ready-made maps of some regions of Russia and some other countries, however, these maps do not cover the whole world and are not always made as we would like. By converting the card yourself, you can achieve much more, if not a pity for the time, of course.

Briefly and for those in the know, the conversion looks like this: .osm -> .mp -> .rus / .nm2

Disclaimer - I describe the method that I use myself. If you know the easier way - you are welcome to write in the comments.

Well, now - in detail:

1) Download.osm
.osm is the vector map format for OpenStreetMap. It is based on XML i.e. actually textual.
You can get the .osm file in the following ways:
1. Download by editors: JOSM or Merkaartor. Just download the map rectangle you need from the server and save it to a file. I personally prefer to use JOSM, but Java needs to be installed for it.
2. Download a ready-made map of a certain region from one of the hosting, for example:
- geofabrik.de - continents as a whole and cut by country, some countries are chopped into provinces / states / regions
- cloudmade.com - the whole world by country, some countries are chopped into provinces / states / regions
Just download the file and extract bz2.
3. Download manually via XAPI
To work with XAPI, you need to compose an HTTP request to the server, nothing complicated, the link says everything.

2) Cut .osm into pieces(If you want to)
.osm files, especially those prepared by country, can be quite large and do not go through subsequent conversion (see below). Therefore, they have to be cut.
For cutting, I use splitter, by default it makes .osm files somewhere around 120 MB, which then almost always go through the subsequent conversion. The splitter can be configured with command line parameters if required.
The splitter requires Java to work.
Also, keep in mind that in Russa, routing works only with one loaded map. Those. if the map of one country is cut into pieces and loaded into Russa as an atlas, the routing will not work.

3) Convert .osm to .mp
.mp is an ancient Polish format for storing maps. It is good because it is textual and quite human-readable, well, and a lot of programs understand it.
For conversion I use osm2mp program. Unfortunately, the program requires Perl to be installed and is not very easy to use.
One way or another, after installing and configuring Perl (described by the link) and downloading osm2mp, the program can be used.
An arbitrary .osm file must also be pre-ordered - processed by the attached osmsort.pl script
Then you need to call osm2mp.pl specifying the conversion parameters.
Through lengthy experiments, I wrote a set of .bat files for myself, for example, a standard conversion with a scope for Russa:
echo Start% date%% time% >> std_err.log echo% 1 >> std_err.log perl.exe osmsort.pl% 1> temp_del.osm 2 >> std_err.log perl.exe osm2mp.pl --header header_russa. tpl temp_del.osm>% 1.mp 2 >> std_err.log echo Finish% date%% time% >> std_err.log
You need to call such an .bat file with 1 parameter - the name (and full path) of the .osm file
The 1st line writes to the std_err.log file the date and time of the start of the conversion
2nd line writes the name of the .osm file to the std_err.log file
3rd line executes osmsort, information about the process (and errors) goes to the std_err.log file
4th line executes osm2mp, information about the process (and errors) goes to the std_err.log file
5th line writes the date and time of the end of the conversion to the std_err.log file
(The path to perl.exe must be written either on the system or in your .bat file)

To convert maps of foreign countries, it is advisable to turn on transliteration - otherwise the names. For example, adding the following parameters "--nametaglist int_name, name: en, name, name: ru, ref, int_re f, addr: housenumber, operator --translit" right after "osm2mp.pl"

To convert with a scope for Navitel, you need to download a set of osm2navitel configuration files, rename the files there respectively to header_navitel.tpl, poly_navitel.cfg and poi_navitel.cfg; and add the parameters "--osmbbox --navitel --disableuturns --header header_navitel.tpl --cfgpoly poly_navitel.cfg --cfgpoi poi_navitel.cfg" to the osm2mp.pl call

For other conversions, you can also prepare poly * .cfg, poi * .cfg and header * .tpl

A large card may not convert - for example, 32-bit Perl is limited to 2GB of RAM, as a result, osm2mp cannot cope with .osm files of anywhere from 700MB, and sometimes crashes with a memory error on significantly smaller cards. In this case, the card must be cut (see step 2).

4) Convert .mp to .rus (or .nm2)
For this purpose there is an excellent program GPSMapEdit, which, as the name suggests, is also an editor. It is enough to load the .mp file into GPSMapEdit and export to the required format.
But there are several pitfalls:
- Files .rus (and .nm2) saved from GPSMapEdit have a size limit of 16MB. According to my estimates, this corresponds to about 120MB of the .mp file, or about 600 MB of the .osm file.
- .nm2 files for Navitel 3.2. * Versions are very demanding on the absence of errors on the map, so if "Export failed" occurs, you will have to correct the error on the displayed map, or choose a different format, or convert the map with different settings (see step 3).

P.S. , and then convert to .rus or .nm2.

Most people's knowledge of OSM is usually limited: "This is a map that ordinary people draw, like Wikipedia." Further, we often hear that OSM maps are not suitable for tourism, that there is no relief, passes, etc. This is not the case, and I became convinced of the need to write an educational program.

• What OSM really is;
• Why do tourists need it;
• How to get information from OSM when planning a hike;
• How to use it already on the route;
• A little about drawing (addition) OSM.

What is OSM?

This is not the map you see on openstreetmap.org!

95% of the population who have heard about OSM will go to this site, see this and reasonably do not experience a special surge of emotions.

OSM is a database. For ease of understanding, imagine a file with a tablet, where the coordinates of points or lines are written in the first column, and in the second column what these points and lines represent. Here is such a plate - this is OSM. Of course, I have simplified the plate now, but the main thing is that you understand that OSM in its original version is just such a boring plate, and not a beautiful multi-colored map or even a picture.

The data from this plate is used to make…. anything!

From electronic maps for tourists to power grid diagrams or a poster on the wall showing the route of buses in your hometown.

One of the OSM maps for viewing from a desktop computer or phone screen. (Open Topo Map) One of the OSM maps for the Garmin handheld navigator
volumetric map for the blind, printed on a 3D printer based on OSM data. They do. Germany power grid map
nautical chart at http://map.openseamap.org/
OSM map in popular mobile application Maps.me

Everyone who creates a graphic representation of OSM chooses for his own taste and color how certain objects will be presented there. And will they introduce themselves at all. As you can see in the pictures above, those who needed a power grid map ignored all objects in the OSM database, except for those related to power grids. And the creators of Maps.me, making a map for navigation in the settlement and nearby, did not insert power lines, mountain passes and fords into their map. The creators of the nautical chart are pulling out the third from the database.

That is, if I really want to, then I can make a map where only seas, benches and wells will be displayed. And the seas will be red, the benches will look like the UN flag on the map, the wells will be displayed on the largest scale (when, what scale is shown, can also naturally be different) and will be drawn with crosses. Updating (pulling up-to-date information from OSM servers) my psychedelic map will be every full moon (who puts how, and I love the full moon!). Nobody will need such a card, but in theory it can be done 🙂

Therefore, there is no OSM Map Legend list. Each graphical representation (type OSM / rasterizer - you may come across different names) will have a different one. I will describe below how to get information from OSM. It will be interesting even for those who are intuitive about the designations on the maps, because, as you probably understood, there is not a single OSM map that would display everything in the database at once.

Why do we need this?

You can read more about the maps used to prepare for the hike with me.

Yandex and Google maps they are not applicable for forests and mountains - I hope this is understandable. No paths, no necessary objects, no relief. Corporations are not interested in being distracted and drawing a path along which 100 people will walk in a year. It is not interesting to depict a spring in a forest, and such an insignificant number of their clients need the passes that they will most likely never appear there.

But in OSM there is a lot of information that a) does not fit on the map b) is not cartographic in principle. If a competent OSM operator has walked around the area before you, then you will receive a lot of information that you are usually used to getting from the reports of sports tourists. ( By the way, reports sometimes lie and embellish reality because of motive, crusts and discharges, but there is no motive for the OSM editor to lie.) And then this information is immediately tied to the area, and not in the form of text. If the area is poorly drawn, then you are out of luck and it is in your hands to fix it.

I will show you the simplest way of extracting interesting additional information from OSM, which does not require installation of any programs.

Tags, this is cool, of course, but OSM also provides the ability to plot a route (prepare a track for a hike) along paths / roads automatically, rather than manually clicking on the map. This can be done in the Android application (there is also a package of maps for it from here) or on the gpsies.com website (the main thing is, when saving the track, tick the box that this is your plan, and not the track that was actually covered), or in the SAS Planet program ( here it is pathetic).

OSM en route

OSM - vector maps, so it is convenient to use them in navigators (automatic routing along tracks, zooming without loss of quality, searching for objects). As usual, we have a choice between Garmin and a smartphone.

OSM Maps for Garmin Navigator

Convenient OSM assemblies suitable for backpackers under the backpack, daily updates:

• https://maptourist.org/osm-garmin - the entire former USSR + Mongolia. The link contains the gmapsupp.zip file, after unpacking it and placing it on the memory card in the device in the Garmin folder, you will receive a map of the entire former USSR. There are also separate files for the Federal Districts of the Russian Federation and Mongolia. This assembly displays the passes with categories;
• http://garmin.openstreetmap.ru/federal/ - Russia with files by federal districts (the archive must be unpacked using, for example, 7zip and simply dropped onto a memory card in the device in the Garmin folder);
• http://gis-lab.info/data/mp/# - regions of the Russian Federation and some countries in separate files. There are also instructions for filling, including through Base Camp.

In OSM, users are constantly making changes, and the above assemblies are constantly updated, so by uploading the map right before the hike, you will receive the latest version.

In many maps, contour lines are missing. They can be supplied separately.

The relief files are permanent, so I collected them here: https://yadi.sk/d/olnB_ueyxHJW0g They are also easily filled in. After installation, you will see relief files in the list of instrument maps as separate items, which allows you to turn them off when they are not needed and interfere with viewing the map.
Follow the link readme file, horizontals of all of Russia and separately the rest of the world from 60 * SSh to 56 * YuSh. You can download both files and torrent files at once. The contours are a splicing of SRTM and ASTER GDEM satellite scanned data.

with Garmin it seems sorted out.

OSM in smartphone

There are a lot of options. The simplest one is:

The OSMAnd application did not impress me with the fact that I was never able to download a non-OSM map offline. Since on a hike I use my smartphone, including as a backup storage for maps and satellite images.

A little about drawing (add-on) OSM

Ideally, the map should be completed before and after the hike.

• Before the hike- to prepare the maximum card for your loved one. You can mark forests, rivers, ridges, clearings, roads visible on satellite images.
• After the hike- because it is interesting and to share the information that you have collected during the hike. Much can only be mapped after you have seen it yourself. The quality of the trail, the number of sites for tents, springs, wells in villages, the depth of the ford, etc. and so on

The simplest editor is right in the browser. It's called the iD. Go to https://www.openstreetmap.org

If this is the first time you do this, you will have to register (login and password will be useful for other editors).

It is very simple, but there are few opportunities, many things in it are long and inconvenient to do, and you can easily break something.

The best thing to do is to master the JOSM editor. This is already a separate program on the computer. There are a lot of bells and whistles, the ability to add a cloud of all kinds of satellite images, upload your tracks and points, watch the entire history of object changes, etc. etc. The main thing is that the editing process takes place offline, any action can be safely canceled with the usual Ctrl + Z. When you are finished, press the button “send data to the server”, the program will check your edits, offer to check the box “I want someone else to check my edits” (check it first), and ask you to specify the data source for the new batch of changes. And only after that, the changes will fly to the server where the database is stored. On the openstreetmap.org site map, the changes will be displayed right there, in those assemblies for Garmin that I threw above - in a day, and, for example, the same maps.me, updates the map once a month.

Instructions for using JOSM: https://josm.openstreetmap.de/wiki/Ru%3AIntroduction

Video instruction in which it all starts with setting up the program: https://www.youtube.com/watch?v=t7UdJrX8nGM

These two instructions (you can find more if you want, including on YouTube) will teach you the technical part. To find out which tags are used to designate certain objects, use the search in OSMWiki (search box at the top right). With a little experience, you will remember the tags you use and you will be less likely to climb Wikis.

Common mistakes beginners make:

• draw under the rasterizer. Let's assume that you are using maps.me for navigation. He does not draw passes ( mountain_pass=yes), this rasterizer was not designed for trekking. But you want to see the passes in maps.me on your smartphone. And you start to mark the passes like tourism = viewpoint ( this tag is supposed to mark places with a good view) which is displayed in maps.me. This is not correct, since in their meaning they are different objects, clearly described in the Wiki. And these are your problems, that your rasterizer is not showing something. For another person, everything is possible well, and he needs to distinguish a pass from a specific place. Even if none of the rasterizers displays what you need, if the database is maintained properly, then it is possible to create a suitable rasterizer for your purposes or make changes to an existing one. For example, I was missing in the assembly for Garmin https://maptourist.org/osm-garmin rtsa_scale = *. If everything is written in continuous text on one line, then the electronic brain will not cope. If you have information that you do not know how to tag, but is useful to the end user, write it down in the tag value description= *. For example, I write to the point shop = hardware information about whether I have come across refined gasoline for burners there.
• redraw from other cards.In general, this item was invented in the West because of all sorts of legal and monetary problems. Yes, Google and Yandex will be very opposed if you start using their cards, on which they spent money, for the sake of a card that is distributed for free. But this rule, as the saying goes: "not a bug, but a feature." It allows us to ensure that the path that I see on the OSM was drawn from the GPS track by people who actually walked there, and the clearing is visible in the satellite photograph, and not copied from the General Staff map, which has not been updated for decades. Of course, the trail on OSM could also be overgrown, but, preparing for the hike, we look at all available maps, and if the trail is drawn on all maps, then we will be sure of its presence, and if it is not on some map, we we will no longer rely on it and plan our actions accordingly. And if the cards start to redraw one with the other without checking with reality, then it will be nonsense. In addition, you already know how to look at the date of creation of a trail in OSM in order to estimate its presence at the moment, and you know how to delete an object if it is still not on the ground.

We often hear that, since any person can edit OSM, then someone may come there who will erase everything or paint schizophrenic delirium. If this happens infrequently, experienced users will be successful in detecting and fixing it. And it’s too difficult and doesn’t scratch the Vandals' CSV - register somewhere and spoil the map. The abundance of users, of course, increases the number of people who are not familiar with the technical part of mapping, but there are more and more experienced users who will correct for newbies.

This was an introductory course to OSM. Enough for a start :)

Join the hikes through my group.

There is nowhere without navigation, especially considering the condition of our roads. Notice that your navigator is unstable? Then you need to download OSM maps for Navitel as soon as possible. They contain all the necessary information about the settlements of the country, POI objects such as restaurants, bars, and places for cultural recreation are marked on these maps.

OSM maps for Navitel are more than just navigation. This is a project that is created by enthusiasts with their own hands. The service provides raster maps of the area, and navigation services based on them create the maps we are used to. This approach makes it possible to organize navigation as accurately as possible.

The OSM project is a completely non-profit project. This suggests that all cards are provided free of charge under a general public license. Moreover, Open Street Map acts as a wiki, which allows everyone to make changes to the maps, and this makes OSM even better, better quality and more popular.

Why is OSM worth using?

Open Street Map has several advantages over other projects of a similar nature:

• accuracy;

Navitel OSM maps are so detailed that with a 99% probability every hump and uneven terrain that is on the maps will be encountered in real life. This is due to the fact that maps are constantly being improved by the OSM community on the Internet. As a result, edits are made, old versions are updated, and new maps are improved.

• free distribution;

The project is funded by a donation. This made it possible to absolutely download all OSM maps for Navitel. At the same time, the quality will be far from worse than that of paid services.

• wide girth;

Unlike most projects, OSM maps for Navitel cover the entire globe. Therefore, using them, you are guaranteed to know how to get to the place you need in an unfamiliar country or continent. Moreover, OSM outperforms some of its paid counterparts - TomTom / Tele Atlas in accuracy. According to research, the accuracy of Open Street Map exceeds these maps by 27%.

• convenient use;

Maps can be imported in any convenient format - PNG, JPEG, SVG, PDF or PostScript. Also, it is possible to load them into Garmin, GisRussa.

The WIKI format allowed OSM to create a unique cartographic project. After all, the fact that the maps are being finalized by the inhabitants of the area, gives undeniable advantages. Firstly, the accuracy is extremely high, and secondly, the reliability is ensured. And thirdly, it is the general availability of the OSM map for the Navitel. You can download them on our website for free and without SMS.

In this practical article, we will consider services that help download maps from the OpenStreetMap online service for subsequent conversion to other cartographic formats to use them offline without an Internet connection.

It is summer now, and for many, this is the main time to travel. Therefore, it's time to get navigators, or put special navigation software on tablets and smartphones, so as not to get lost in unfamiliar places. Moreover, there is no shortage of such programs in the current era of GPS and mobile devices. It offers users both geographic Internet services like Google Maps and Microsoft Bing, and specialized software like 2GIS with its own maps.

The latter option with local maps, which users pre-download and install for their navigation software, in many cases is not only more convenient, but also the only possible solution. Since the Internet in a particular area may be expensive or not work at all. But at the same time, the required offline maps of a specific area may also be missing.

Below we will consider options for downloading map data from the OpenStreetMap (OSM) online service with the subsequent purpose of converting this data into a specific map format for your navigation program. We have already covered the OpenStreetMap project in detail. It is an open-source web mapping service, similar to Google Maps, whose data is collected by the users themselves and is available to everyone under an open license. In the article, as an example, we will consider the conversion of OSM data for the OsmAnd program for Android devices, which we also examined in detail on the KV website.

OSM official website

So, we need to download OpenStreetMap map data for a specific area. First of all, this can be done from the official website of the service www.openstreetmap.org.

Directly on the online resource map there is a link "Export", when you click on it, the data export panel will appear. Here, using the blue button "Manually select a different area" (manual selection of a special area), you need to select a rectangle of the required territory on the map, then select "OpenStreetMap XML Data" from the list of formats and press the "Export" button.

As a result, a file with the osm extension will be loaded. This is a text xml file with map data, which can then be converted to other formats.

However, the official site imposes restrictions on the amount of downloaded map data. The loaded map must not contain more than 500 nodes. And any city - it will always be more than 500 nodes. But there are other services that allow you to download the desired geographic area without such restrictions.

Whole planet

Here you need to select the desired area on the OSM map, and in the special fields indicate your e-mail address and specify the name of the selected map. It is important that the service makes it possible to download a map not only in OSM format, but also convert it to ready-made formats Garmin, Navit, Esri.

Since the "drawing" of a specific terrain map on the service comes from planet.osm, this takes some time. The result will be ready in 15-30 minutes, depending on the size of the map area and the load on the service. As soon as the card extraction process is completed, the user will be notified to the e-mail address left by him.

Converting

Thus, having received the cartographic data of a specific region in the form of a text osm file, you can start converting it into a ready-made map format with vector or raster graphics for a navigation application. For example, for the OsmAnd software GPS navigator, you need to convert OSM map data to OBF format.

There is a special converter OsmAndMapCreator for this. This application is written in Java and is cross-platform. It is launched after unzipping, depending on the operating system, by the sh or bat script. But the program has a graphical interface.

You need to convert the osm file through the menu "File" - "Create obf file from osm file". After that, a file with the obf extension will appear in the pre-specified folder, which must be transferred to the Android device in the / sdcard / osmand / directory. Now the map of this area will be available in OsmAnd in offline mode.

Using OsmAndMapCreator, you can create OBF maps using data from other online map services. But an overview of these program features is beyond the scope of this article.

Mikhail ASTAPCHIK

(literally " open street map"), Abbreviated OSM- a non-commercial web cartographic project for the creation by the community of Internet users of a detailed free and free geographic map of the world.

To create maps, data from personal GPS trackers, aerial photographs, video recordings, satellite images and street panoramas provided by some companies are used, as well as the knowledge of the person drawing the map. Using services like Google Maps to create maps is not possible without the permission of the copyright holder.

OpenStreetMap uses a wiki principle to create a map. Each registered user can make changes to the map.

Now we will begin our story about how to make changes and additions to this rather detailed, evolving and easy-to-use map.

First you need to go to the official OSM website http://www.openstreetmap.org/. You can enter the site either using your personal mailbox, or by linking an existing account in various communities, the icons of which are shown in the figure:

After entering the site, we will have the same picture as in the title photo of the blog. The page header contains the main menu with all the supported commands and provided capabilities.

Now a completely natural question arises: how can you edit the map?

The map can be edited both online, using two online editors: iD and Potlatch 2 - and offline, using the editor installed on the computer. The second method is convenient for those who have a very low Internet speed or there are restrictions on the traffic used, where all changes can be made on your computer, and then sent to the OSM server. Edits are sent as an XML file, so they won't have a significant impact on traffic.

In this article, we will edit the map online using the iD editor, because the principle of work of editors iD and Potlatch 2 is the same, only Potlatch 2 allows you to map a larger number of different classes of objects and because of this it is more inhibited. A fast iD editor is sufficient for drawing and editing on the road map.

In the upper left corner we have three highlighted items "Edit", "History" and "Export". Moreover, the "Edit" item is inactive. When you hover the mouse cursor over it, a hint appears that you need to zoom in for editing

After enlarging the map to the desired scale, the "Edit" button will become active, when you click on it, a pop-up menu will appear, where you can select the required map editor.

Select the iD editor and start working with the map. You can make changes to the map either manually, using satellite images provided by the OSM service, or by plotting the paths obtained from the traversed tracks saved in the navigator. The following image shows the editing window for the map by the iD editor. Editing will become available only after zooming in, and the scale must be very large. The figure shows the extremely small scale that is available for editing. As you can see, this scale is not very suitable for drawing objects from space images, but it can be used for drawing roads using GPS tracks.

As you can see, the editor is very simple and allows you to draw only three types of objects on the map: point, line and polygon. As you might guess, a point is the name of a certain place or a point object, a line is roads, a polygon is various areas (forests, settlements, houses, etc.).

On the right-hand toolbar, only two buttons are of interest:

setting the background. Those. what will be displayed on the map (Google image, OSM map, etc.)

card data. With the help of this button, GPS tracks are loaded from the editor, and also select those classes of objects that should be displayed or hidden on the map during editing.

Now let's figure out how to put objects on the map. I saw that during the ride, the route passed in places along forest roads that are not on the OSM map. It is necessary to correct this shortcoming. To do this, download a real GPS track from Rafael and start mapping roads using a real GPS track. In this example, I want to paint a beautiful forest path that we had before stopping at the lake. Here is a photo of this track:

The track is loaded, now we need to draw this road.

In the figure, the loaded real track is shown in pink, the white line along the track is the road plotted on the map. Any applied object can be edited. To do this, simply select it with the mouse cursor. The object doesn't have to be yours. To complete drawing a line on the map, click on the last point. The start point and end point of the line are important because they determine the direction of movement. This is especially important when drawing one-way roads and rivers. But at any time, the direction of movement can be changed by selecting the appropriate icon that appears after the activation of the object. On an existing object, you can change the position of existing points, add your own (drag the arrow located between the points), and delete points. Those. there is nothing complicated here.

When you select a newly drawn object, the object type menu appears on the left side of the screen.

We have a road, so we choose it. After that, a list of possible roads will appear. We have a forest road, so we choose it.

After that, we enter the necessary attributes of the forest road. These attributes are important for the OSM map, because in the future, automatic navigation is made using them, depending on the selected vehicle, as well as the ability to display an object on the map, when discarding unnecessary objects (for example, a Ferrari will not go along a forest road, so the driver of such a car will not want so that field and forest paths litter the map and participate in automatic routing).

For the created road, I entered the following attributes:

Coating: unpaved

Width: 3m

Legal access: bicycles, motor vehicles, riders, pedestrians

Country road type: Rather soft: rolled soil with admixtures of hard materials

Passage: Strong wheels: hybrid bikes, cars, rickshaws

The difficulty of the mountain bike trail: 0: smooth gravel / trampled ground, unobstructed, wide turns

Difficulty climbing mountain bike: 0: Medium rise<10%, гравий/утоптанная земля, без препятствий

Any action can be undone before the data is sent to the server. If you forgot to define the type of object or assign attributes to it, but at the same time reached the step of entering a comment, the last step can be canceled (pressing "Save") by closing the comment input window, while the unsaved object will not disappear anywhere.
