Hi Benoît, For your regular cells a GridCoverage2D can store data of the type that you describe. Each cell can have multiple values. You can convert the grid to other projections.
See http://javadoc.geotools.fr/2.6/org/geotools/coverage/grid/GridCoverage2D.html To my knowledge Geotools doesn't presently support irregularly gridded data. Depending on the specifics of your data you could handle this with a vector layer instead. I've done something similar when working with a lattice of different sized, but still tesselated, cells. You might also want to investigate JGrass which I think supports TINs (triangular irregular networks): http://jgrass.wiki.software.bz.it/jgrass/JGrass_Wiki Michael 2008/11/19 Benoît Thiébault <[EMAIL PROTECTED]>: > Hi ! > > I would like to manipulate data in a 2D grid (at least viewing it, > changing its colors, changing its values, converting from a projection > to another, etc.) > > This grid, in a first step, is going to be cartesian and regular, i.e. > with dX and dY constant, each cell being a rectangle. > > The grid will contain values (water depth for example, but other infos > as well), located in the center of the cell or on the edges of the > cells. > > Is the GridCoverage2D class adapted for this usage ? > > In the future, the grid is planned to be irregular (dX and dY will not > be constant, thus one will need to store each dX and dY or the > position of all points of the grids) and even one day with cells that > are irregular quadrilaterals.
