[mapserver-users] Σχετ: Mapserver can't read mapfile

[Jeff McKenna]

Hi Stefanos,

Some comments:

- the best way to get the exact extent is to use the ogrinfo commandline
utility with the "-summary" switch:

  ogrinfo dasarxeia.shp dasarxeia -summary

- be careful with your SHAPEPATH, if your file is
/home/mapdata/data/dasarxeia.shp then I would put for your SHAPEPATH
"/home/mapdata/data/"

- when using shp2img, at the end of the command add "-all_debug 3" to
see more useful error messages/notices

- sometimes extent values in QGIS can be confusing, because sometimes it
can display the data in a different projection without you knowing it
(Project Properties/CRS/Enable 'on the fly' transformation)...so be careful
