datum and projection of Mongolia and Kazakhstan by GIZI map

Hi,

sorry, no idea what projection they use!
You can not simply calibrate in lat/lon 3x3 mode ?

Hello,

I try to calibrate 2 maps from GIZI map. (I think that is like Freytag & Berndt )
Mongolia and Kazakhstan/Uzbekistan.
Somebody knows Datum and projection of this maps ?

Maps with a scaling 1:2000000 or 1:3000000 is not good solution for using by GPS. For Maps with this scale you don't need the Map Datum. The accuracy is lower as the difference of serval Map Datum. Maps with this scale using in normally a Lambert Projection. Search the data for the orthodrome in the border of map.

A better way is, you download the Russian military maps.

If you want a commercial map for Kazakhstan and Mongolia, then buy calibrated maps by Bernhard Spachmüller:

This map are ready to work with TTQV.
