[GRASS-user] New to GIS

Hi Jamie,

The data sets must be geo-referenced; they can not be image files, like a
jpeg -- files like this, if used, would need to be manually referenced to a
coordinate system in order to be usable in any way. Probably what you
should do if you are new to GIS is to read the basics of GIS before
proceeding. Otherwise you will make mistakes that are can be avoided. You
first have to know what it is you are trying to do and work from that point
going forward. Googling very specific questions (the more specific the
better) -- just explore.

Data format is relevant insomuch as it relates to whether or not the
dataset is georeferenced (Google this word!!!!), such as GeoTiff vs Tiff --
the geotiff includes information with respect to map projection and
geodetic datum -- these concepts are critically important...

BTW, please respond to 'All' to keep the discussion on the GRASS Users
mailing list so others can possibly contribute -- don't just reply to me.
