[GRASS-user] wms import fail

[Maris Nartiss]

Hello,
the problem is that some layer names have non-latin (Estonian) letters
and current code is not ready to handle such cases. I can try to look
at the code later (have to test changes) (as soon as I will recover
from Jaanipaev).

Still Maaamet watermarks their WMS service, what could interfere with
any automatic analysis. Example here:
http://kaart.maaamet.ee/wms/alus?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&BBOX=658960.012556,6474081.356986,659242.751929,6474249.416589&SRS=EPSG:3301&WIDTH=1152&HEIGHT=685&LAYERS=of10000&STYLES=&FORMAT=image/png&DPI=109&TRANSPARENT=TRUE

Maris.

PS. As I spend some time in Tartu, I would like to know if there are
any other GRASSers in Tartu too as it would be fun to have a beer :)
