[Geotools-gt2-users] GIS, GeoAPI tutorial?

[Jesse S. <jes...@gm...>]

Is there some tutorial somewhere for those of us who are new to this world
of Geo APIs?  Ie, something with some nice examples of how one might go
about solving simple problems given some input file (say a GeoTIFF file,
eg)?

I've been studying the code for a bit, and have slowly learned how to get
around my earlier issues with a NPE (it should really give a nicer message
when the EPSG data isn't available :) ), but I'm completely new to all of
this.

Do the APIs provide easy ways to do things like the following:

   - Find the pixel position of a given geographical coordinate?
   Translate that position based on scaling the image?
   - Find the distance between two pixels within the raster based upon
   the geographical data in the underlying geotiff?

I apologize if these are questions that get asked often.  As I said, I'm a
complete newbie and am trying to pick this stuff up from bits and pieces on
the web.  The whole terminology is pretty foreign to me.  :)

Thanks for any help,
Jess
