I've received some very useful maps of Albania for my work (scale 1:25000) and I would like to georeference them in order to put them together to one Map for my destined regions.

Unfortunately I cannot find the projection of the maps, they don't seem to be written on the map (it is unfortunately in Albanian language).

What projection might it be?

I'm using QGIS.

  • The coordinate system is printed on the left upper corner in Albanian. It says "The national coordinate system". On the upper right side it says "SEKRETE" meaning classified map. Congratulations! – multigoodverse Feb 6 '15 at 12:46

General projection of these maps is Pulkovo 1942/ Gauss-Kruger zone[zone number]. For this particular map it is Pulkovo 1942/ Gauss-Kruger zone 4

EPSG:28404; proj4 code:

+proj=tmerc +lat_0=0 +lon_0=21 +k=1 +x_0=4500000 +y_0=0 +ellps=krass +towgs84=23.92,-141.27,-80.9,-0,0.35,0.82,-0.12 +units=m +no_defs

UPD: I fixed incorrect zone number 3 -> 4

  • It worked! Thanks a lot! Where could you see this on this map? – Lukas Jul 8 '13 at 7:02
  • Ok Now I don't have the slighest idea how to read to koordinates. If I type for example X: 42054662 and y: 2022(30??)4449 (koordinates in the down-left corner of the map) I stay somewhere near Africa. How do I have to interpret those numbers? Sorry I feel very dumb now :( – Lukas Jul 8 '13 at 9:27

    @Luka, I'm just familiar with these Soviet-school military maps. You need to add 000 to each coordinate when you georeference it: 4662 -> 4662000; 4458 -> 4458000 – SS_Rebelious Jul 8 '13 at 9:51
  • Hi there, it's me again. And I'm asking myself: The Projection you suggested is suggested to use for a different area (georepository.com/crs_28404/…) more around Poland... Are you sure this was right? Sorry to be so pushy – Lukas Sep 26 '13 at 15:12
  • @Lukas, I'm sure. This CRS (don't mess CRS and projection) is suitable for any area within the certain longitudes (and Albania share same longitudes with Poland). You should find a handbook on geodesy if you want to be familiar with how this CRS staff works. – SS_Rebelious Sep 27 '13 at 3:09
