I believe I have found 2 bugs in gdale_retile.py: 1. It appears that gdal_retile.py does not honor alpha bands for masking when merging images. At this link is an image which shows my two images loaded separately as tiffs into google earth:
http://imgur.com/9HcFh At this link is an image of the output of running gdal_retile.py on my two images to form an image pyramid: http://imgur.com/AuDOO Here are the commands I run on the images to make the image pyramid: gdal_translate -expand rgba 12Jun29_1643-f-17.tif output12Jun29_1643-f-17.tif gdal_translate -expand rgba 12Jun29_1643-f-18.tif output12Jun29_1643-f-18.tif gdalwarp output12Jun29_1643-f-17.tif finaloutput12Jun29_1643-f-17.tif gdalwarp output12Jun29_1643-f-18.tif finaloutput12Jun29_1643-f-18.tif gdal_retile.py -v -r bilinear -levels 4 -ps 2048 2048 -co "tiled=YES" -targetDir testpyramid --optfile files.txt If I explicitly mosaic the images first, and then feed the mosaic into gdal_retile.py that will work, but this solution does not scale well. 2. gdal_retile.py expects that images are north-up, thus why I run the gdalwarp on them before gdal_retile.py. Is this the correct forum for posting these bugs?
