Aaron, This could be solved by using the nodata attribute. You can set the nodata value in the source in the vrt file[1]. The vrt driver will ignore the nodata areas. If you have problem with that, rerun the gdalwarp operation and make sure you get the nodata values. Use the -srcnodata and -dstnod

Jeff, The coordinates you are using with -te are not in the coordinate system of the image. >From the docs -te xmin ymin xmax ymax:set georeferenced extents of output file to be created (in target SRS). Convert the lat/lon coordinates you are using to the srs of the image and then try it. Mi
