It depends which data you need :
- Shape file: vector data
- Esri Grid: raster data
so these data may be/are different.
a common workflow I do with data in different projections:
- Defiine a projection in which you want to do your analysisi(1)s
- Reproject data in different projections than (1) either by
gdalwarp'ed/ogr2ogr or by v.proj/r.proj to this srs/projection
In this way data projection mixing can be avoided.
Helmut,
Good advice and clarification. This completely answers my question.
Thanks,
Rich
