Thank you for the help, Simon! I'll take a look at the manuals too.

Assunto: Re: [Gvsig_english] Raster support on GVSIG

Edson,

The latest version of gvSIG is 1.9. Spanish manuals are available at
http://www.gvsig.org and English versions are being prepared.

The manual for the earlier version, version 1.1.2, is available at
http://www.gvsig.org/web/docusr/manuales-en and discusses the basic
concepts.

gvSIG can display and manipulate jpeg, jpg, gif, png, bmp and svg (+
more). Although some require header files containing georeferencing data
to be displayed correctly.

gvSIG can also connect to GeoDB, WCS, ArcIMS, WMS, Annotation and WFS
internet services that can contain image data.

Usually JPG or PNG files require header files that contain the
coordinates of the upper left corner and the pixel size. A typical
example can be seen below.

For a file called "JPG_Image.jpg" you would have a corresponding file
called "JPG_Image.jpgw". gvSIG also creates an "aux.xml" and "rmf" file
with the same data.

The content of the different files look like this...

*JPGW*
