[Gvsig_english] Raster pilot and CRS (Cordinate Reference System) extensions are now available in gvSIG

[Mario Carrera]

In the past, we always said that gvSIG has the purpose of cover every 
needs regarding the use of the geographic information by the integration 
of free technologies.
Following this roadmap, we can see gvSIG as a platform for the 
full-manage of the geographic information. Thus, every user can install 
the set of tools desired.
One of the working areas is related with the raster GIS and 
teledetection. It is inspired by this way-to-do and approaches the 
vector GIS to the raster GIS.
Now, we release the pilot of the company which won the public tender to 
develope the raster extension of gvSIG that allows to open new image 
file formats, apply color palettes to a DTM, the generation of 
histograms, to cut raster layers and define some new rendering filters.
We'd like also report the next release of the new module for the manage 
of CRSs (Coordinate Reference Systems), that features the possibility of 
CRS's databases (complete EPSG, IAU2000, and others), transformations of 
3 and 7 parameters and transformations based upon a grid, and in general 
to get a maximum precision in CRS reprojections

Both extensions can be found in the 
http://www.gvsig.gva.es/index.php?id=1566&L=0. They are designed as 
regular extensions that can be plugged in to any of the gvSIG 1.0 stable 
versions (gvSIG 1.0.x)
