I am working on a Java application which develops an elevation data raster product that I would like to store in a GeoTIFF file. Some of my input data comes from shapefiles with associated .prj files. I would like to be able to extract relevant information from the .prj files and use it to populate GeoTIFF tags for output.
Can someone point me toward example code I could look at or maybe a general outline of the steps for doing so? I have been looking through the documentation, but need a place to start. Some of my sources come with EPSG codes that I can use to populate the GeoTIFF ProjectedCrsGeoKey (GeoTiff spec section 6.3.3.1). However, others carry general datum and map-projection parameters, so I would have to populate multiple GeoTIff elements. A few of my data sources are in geographic coordinate systems. I am currently working with the Apache Commons Imaging API, which I know pretty well. I've used it to create GeoTIFFs in the past with good results. So I'd like to stick with it if at all possible. Thanks in advance for your help. Gary
