[Gdal-dev] Fwd: gdalwarp with change in projection for tiles then adjacent tiles overlap slightly with a black border at edge.

Frank,

Is their any plans on getting rid of the black border that you get when
using gdalwarp to reproject individual tiles which results in the black
border slightly overlapping the image of its adjacent reprojected tile?

If the above answer is no then how would I put in a request to gdal for this
capability.

Thanks,

John Mitchell

Hi,

I have found that running gdalwarp with a change in projection individually
for each tile and splitting them up via gdal_translate that the adjacent
tiles overlap slightly with a black border at edge.  If I instead run
gdalwarp against all the tiles to create a big mosaic with a change in
projection and then split(gdal_translate) them up that I don't have this
overlap.

Is their a way to individually run gdalwarp with a change in projection
against each tile without getting this overlap?

Thanks,
