Hello everyone!!
I converted a DXF file to a shapefile using 'ogr2ogr' command. When I use the
"-t_srs" parameter the system tells me: "Can't transform coordinates, source
layer has no coordinate system. Use -s_srs to set one."
The command '-s_srs' override source SRS. What is the difference between
'-s_srs' and '-a_srs' command? What is the exact meaning of "Assign an output
SRS"? I don't understand that.
I use the '-s_srs' command and when I overlay the shapefile over a map,the
adjustment isn´t very good with the map, so I must make a geographic
transformation. I get that transformation thanks to 'ProjectionUtility'
(ArcView). Its name is Geocentric[9603], ED_1950_TO_WGS_1984_13, POSC Code:8045.
I need to make this transformation automatically. How can I make this
transformation using 'ogr2ogr'? Is it possible?
Thank you very much
