Derek, Since you are rasterizing vectors, you can get the best results if you do it onto the original raster or a blank raster created based on the extents of the original raster. The key here is to create a georeferenced raster prior to burning the vector onto it. You can create a raster that fits perfectly with the original.
GDAL has a simple rasterization utility that can burn vectors onto a raster image directly. You can use gdalbuildvrt to create a raster with modified extents. http://www.gdal.org/gdal_utilities.html On Fri, Mar 23, 2012 at 7:42 AM, Derek Morgan <jdmor...@unca.edu> wrote: > Hello, > > I am in a jam with ArcGIS, and am hoping there is a easier way to do > this with GDAL.
