# Defining map projection of Eastern part of Ukraine

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 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). Nov 22, 2017 at 8:54
• Did you consider spatialreference.org/ref/epsg/wgs-84-utm-zone-37n Nov 22, 2017 at 9:18
• 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

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`.
