Seems like this is a straightforward issue but finding it difficult to solve online.
I have a new crop of 4-band orthoimages, as GeoTIFFs. I want to create mosaics of some tiles. There is a slight pixel overlap at the edges. When I run gdalwarp it always treats the 4th band as alpha, which causes the overlap edges to be lighter than everything else in the mosaic, creating an odd grid pattern were these edges were (when viewing the CIR bands 4-1-2). How can I disable this treatment of the 4th band as alpha? =============================== Michael Smith MS GISP State GIS Manager, Maine Office of GIS State of Maine, Office of Information Technology michael.smith _at_ maine.gov 207-215-5530 Board Member, Maine GeoLibrary Board Member, Maine GIS Users Group State Rep, National States Geographic Information Council [cid:image001.png@01CDD9FD.50D40D40][icons] ***NOTE NEW ADDRESS*** State House Station 145 51 Commerce Drive Augusta, ME 04333-0145 69o 47' 58.9"W 44o 21' 54.8"N
