[mapserver-users] NoData Gap between rasters - Tileindex Layer

2014-08-29 Thread Bartlomiej Burkot
Dear MS Users I have a set of rasters which I warped to epsg:3857 projection using gdalwarp. During the reprojecting the new raster had been rotated by small angle. After that I created a tileindex shape file using gdaltindex and configured layer: LAYER NAME "myname" TILEINDEX

Hi, The image "two_separate_files.png" reveals the reason. If you look at the seam between the images the left side image and right side images do not share the same common canvas (pixels are not placed into same common grid). The area that you have marked as "000 nodata" has not received any i
