Hello, > I cant seem to understand the concept of GridCoverage , and SampleDimension > ,and the meaning of band ??
To get some introduction please have a look at the ImageLab example... http://geotools.org/examples/imagelab.html There is also an associated workbook which contains more explanation... http://snapshots.dist.codehaus.org/geotools/workshop/ImageWorkbook.pdf > Wt i wanna do is divide a certain area ( An envelope i guess) to certain > polygons (rectangles for example), then color each polygon , give some data > based on certain calculations If your 'polygons' will always be the same size and regularly spaced a grid coverage is a good choice. If you need to work with polygons of variable size (e.g. small in some parts of your study area, larger in others) then its probably a lot easier to represent them as vector features (e.g. stored as a shapefile).
