This document summarizes raster file support and functionality in gvSIG Desktop. It discusses supported file formats using GDAL, basic raster metadata viewing and editing tools, histogram viewing, symbology options, analysis views, filters, georeferencing, vectorization of raster data, and new developments like remote sensing extensions and integration with SEXTANTE. It provides example videos and credits various image sources.

3. Raster file formats
●
gvSIG uses GDAL (format list)
●
Most used formats are available
●
img, tiff, jpeg 2000, adf, asc, hdr, …
●
Not all formats activated
●
Can't test them all
●
To support .rik:
●
Ask on mailing lists
●
Provide some test data

4. WCS
raster data is not just files!!

5. Basic functionalities
●
Raster metadata: size, bands, etc
●
Transparency: opacity, per pixel
●
Pixel information
●
Bands display selection
●
Export
●
Brightness and contrast
●
Basic enhacing
●
Scale dependent display

7. Histogram ●
Raw data or
visualized
●
Normal, log. or
accumulated view
●
Export to DBF

8. Simbology
●
Gradients
●
Look-up tables
●
Adapted to
the raster
pixels values
●
GIMP support
smart!!
