I have some orthos and some 3D vector data that I need to reproject from
Clarke 1880 Cape Datum, Lo33 to WGS84 Hartebeeshoek94 datum UTM 36S.
I'm hoping to use gdalwarp (with VRT) and ogr2ogr, but I cannot find the
input projection codes.
Please can someone provide some guidance on this?
Maybe I have to define them? How?
The jpw files for the orthos are typically:
and you'll probably notice that it is not the usual Gauss Conformal
projection, as that would be +ve South and West for this area.
Once the orthos are done I will be needing to transform (as above) a 3D
DGN file and an ASCII DEM file as well. Typical DEM values are:
I'd be grateful for some help specifying the input and output projection
details (epsg codes??)
Thanks & regards,
