[gdal-dev] warp srs: xyz format point cloud

[jratike80]

Hi,

Because you are changing from the raster world into vector world I would it
somehow
- convert raster in native CRS into xyz
- write a vector VRT file for converting xyz data into points
- re-project the point dataset with ogr2ogr

Converting data into PostGIS raster could be more elegant and allows to live
between the two worlds in a flexible way.
