Hello all, we are currently serving many tiff files (ca. 4000 per layer) as ImageMosaic via WMS and WMTS (scale-dependent). These tiffs are heterogeneous (=true), i. e. mix of RGB and RGBI, various resolutions. Therefore we use coverage view and we only display RGB (channel selection in .sld).
One image can have two footprints (because the original image is composed of two different dates, when the photo was taken, each footprint represents one date, but referring to the same image). We've generated unique IDs in the shapefile table, where the footprints.properties is pointing to (footprint_filter = FID = granule.FID --> shapefile for ImageMosaic = footprint_source). Footprint behavior is set to CUT. All in all this works perfectly, but along the footprint line within one image (remember, exact same image is used twice in the ImageMosaic, each time with a different footprint), white (nodata) pixels appear and only occur if the footprint lies exactly in the pixel (divides pixels into 50-50 pieces). <http://osgeo-org.1560.x6.nabble.com/file/t384935/FP01_1.png> <http://osgeo-org.1560.x6.nabble.com/file/t384935/Fp2.png> <http://osgeo-org.1560.x6.nabble.com/file/t384935/Fp3.png> I don’t know if this is a bug. But is there a possibility to adjust the tolerance of the footprint behavior or another way to avoid these pixels? Wasn’t there an option that the footprints can cut through pixels instead of omitting/picking entire pixels? Cutting the images beforehand or interpolation (bicubic) are not an option because the original images should be untouched.
