Distorted Map

[harald1]

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:

end.

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
