Hi,
I am trying to use recent updates of r.sun under CVS version of GRAS5.3 (from Oct 11). I got the following error reading latitude values from proj info:
r.sun elevin=ele25 aspin=asp250 slopein=slop250 day=90 beam_rad=b1a diff_rad=d1a refl_rad=r1a
Mode 2: integrated daily irradiation
Unable to initialise PROJ.4 with the following parameter list:
+proj=krovakgis +a=6377397.155 +es=0.006674372231802145 +towgs84=653.000000,-212.000000,449.000000
The error message was 'unknown projection id'
ERROR: Can't get projection key values of current location
Maybe some new parameters were added to the proj info that have not been included in r.sun. Please let me know if there are some changes, I could overlook some information on the grass list. Thanks.

"proj: krovakgis" doesn't exist any more in GRASS; you need to use
"proj: krovak". I believe Radim made some changes to this to fix the axis
orientation and the version in the internal GRASS PROJ is more 'correct'
than in the remotesensing.org PROJ version.

FYI
Month ago I have submitted a "krovak" update to PROJ4, but it
was not accepted (yet?):
http://bugzilla.remotesensing.org/show_bug.cgi?id=147
The best would be to raise that issue on the PROJ4 mailing list
http://www.remotesensing.org/proj/
Interesting to know is that the Evenden version of PROJ4 (but without
datum transformation) now contains Krovak support:

'krovak' works now like 'krovakgis' in GRASS, if you use external PROJ.4,
you have to apply the patch, see also
