Hi all,
I need to import DCW (http://www.maproom.psu.edu/dcw/dcw_about.shtml) data
in GRASS, and I need to create a location with the correct projection to
import them.
On the DCW web site I read as follows:
COORDINATE SYSTEM DESCRIPTION
The coordinate system is described according to ARC/INFO standards. For more
information, see the project command in the ARC/INFO Users Guide.
General Projection Information
Projection: GEOGRAPHIC
The coordinate pairs are measured by latitude/longitude and
have not been altered by projection algorithms.
If you are using ARCVIEW, the projection MUST be GEOGRAPIC
in order to reproject.
Units: DD
Coordinate pairs are measured in decimal degrees.
Spheroid: CLARKE1866
The spheroid for the data is the Clark 1866.
I created a location with the following projection: +proj=longlat
+ellps=clrk66 +no_defs
Is it correct? What would you suggest me?
Thanks,
Marco
