ogr2ogr reprojection

[Rahkonen Jukka]

Hi,

I cannot make a test right now, nor check the documentation, but if I remember right with ogr2ogr something like -s_srs "epsg:4323" should work if there exists epsg-code for your projection. Similarly -t_srs "epsg:   " for the target projection.

Hi,

what you have said works fine, but now something is wrong again with the srs
definition, the error messages on the console are:

>>>SRS_Def can be a full WKT definition, or a well known definition, i.e.
epsg:4326 or a file with a WKT definition.

in the call_convert.bat, I defined like this:

call convert.bat boundary.shp COUNTRY_region.shp
call convert.bat forests.shp FOREST_region.shp

and in the convert.bat file:

ogr2ogr -init=world:CH1903 -init=epsg:4326 %1 %2

it seems that the project definition "-init=world:CH1903" is not right, but
I use it also in other mapfiles, and it works well.

anything wrong?
