Re: Thematic mapping

Hi Catalin,

You can display this kind of data in OpenMap. You can use a
com.bbn.openmap.omGraphics.OMGrid to hold your data in a
geographically-oriented array. Then, you assign it a
com.bbn.openmap.omGraphics.grid.OMGridGenerator which interprets the
data to render it on the map as a raster, set of polygons, or whatever
you want. There are some sample OMGridGenerator implementations in the
grid package, but you'll probably want to write one that works for your
data.

Hope this helps,

Don
