I have an array of objects where each object has three fields: lat, lon, and category. It is essentially pixels that have been given a land use category. I cannot figure out how to turn this data into a geotiff. I assume I should use geotools. The coordinates are in dec degrees lat long. I know I can use q or arcgis to do this but I need to do it as part of an automated process. Just need a push in the right direction.

You can certainly use GeoTools for this, you will also probably want to look at a relsted project JAITools which does helpful things with rasters. I wrote some code a while back to rasterize circles on to a Grid and output them as GeoTiffs which should point you in the right direction.

  • thanks you @iant, I will mark as answered. Don't have time to try right now but your code looks adaptable to what I'm doing. Thanks! – markgiaconia Aug 13 '14 at 12:34

    Can you point me in the right direction for how to actually write the GridCoverage2D to disk as a tif file? – markgiaconia Mar 6 '15 at 2:06
