I have a map of the Eastern part of Ukraine, which was apparently used in the ceasefire negotiations to define the borderline between the conflicting sides.

The full map: https://informnapalm.org/wp-content/uploads/2015/01/karta-polnayacc.jpg

The map is quite detailed but I could not find the type of projection it uses.
Moreover, it is difficult (though possible) to see the exact numbers.

However, there are some numbers.

  • Coordinate X varies from 7288000 to 7612000
  • Coordinate Y varies from 6192000 to 6608000
  • The gap between meridians and parallels is equal to 4000 map units.

Coordinates X and Y should roughly correspond to

  • Longitude 47.12°N - 49.65°N
  • Latitude 36.15°E - 40.19°E

in WGS84 respectively (I used Google Maps).

The middle of the map is a city called Debaltseve located at 48.33°N and 38.36°E.

Although the headers are in Russian, the names of the places are in Ukrainian.

Thus, I thought that it is likely to be one of the Ukrainian projection systems. I tried to use the epsg.io website and play with the common Ukrainian projection systems it stores but every time I tried to transform the WGS84 coordinates into one of the Ukrainian projection systems, I got an error.

Could you suggest me what kind of projection system the map might use?

    Your map isn't in degrees (Long/Lat), it's probably in metres (Eastings and Northings).

    Did you consider spatialreference.org/ref/epsg/wgs-84-utm-zone-37n

  • Thanks for the hint. It is not the projection system. But I went in a similar direction and played with the Pulkovo projection, which is widely used in the post-Soviet space. It seems that Pulkovo1995 GK Time Zone 7 matches very well after I downsized the y-coordinate by 1'000'000 units. Most likely, I made a mistake interpreting the numbers from the image. 5 and 6 look similar on it. Nov 22, 2017 at 11:20

@nmtoken suggested my map measures coordinates not in degrees but in meters and therefore a sort of UTM projection.

WGS 84 / UTM zone 37N EPSG:32637 did not work. The closest projection I was able to get was Pulkovo1995 / Gauss-Kruger Zone 7 EPSG:20007.

Pulkovo1995, GK Zone 7. The yellow highlighted regions indicate the location the raster should project on

The X-coordinates seem to match but Y-coordinates are biased almost by 1'000'000 units.

I had another look at the raster file and realized that it is difficult to differentiate between the values 5 and 6. I used another Y-coordinates: 5192000 and 5508000.

Adjusted coordinates georeference of the raster. Pulkovo1995 GK Zone 7

Besides the almost perfect match, the image is not squizzed indicating a perfect match.
