Distorted Map

Сообщение harald1 » 29 май 2020, 22:03

Hi,
I have got a zmp from a map (France BRGM). The map is visible, but quite distorted, the x-axis seems longer than the y-axis (see attached snapshots)
The zmp is:

GETURLSCRIPT
Код: Выделить всё
begin
ResultURL:=GetURLBase+RoundEx(GetLLon,15)+','+RoundEx(GetBLat,15)+','+RoundEx(GetRLon,15)+','+RoundEx(GetTLat,15)+'&WIDTH=256&HEIGHT=256';
end.

What is wrong? Can anyone help me? I have no idea...
Thank you!

Sorry, but some kind of nonsense is written in the zmp projection part.
projection = 3
- this is Longitude / Latitude (And it is in it that your map is displayed in SaS, so it is so oblate)

sradiusa = 6378137
sradiusb = 6356752
- these are the values for the ellipsoid that correspond to "projection = 2"

epsg = 4326
- and this is WGS84 on a sphere that corresponds to "projection = 1".
Choose one or
projection = 2
sradiusa = 6378137
sradiusb = 6356752
or
projection=1
sradiusa=6378137
sradiusb=6378137
