Hi all, I have set up an ImageMosaic store with existing TIFF tiles. They are not GeoTIFFs, but regular TIFF files with worldfiles. The index is stored in PostGIS (the information was already present there, I only had to create a view to match the index schema).
In some cases, the stitching of rasters is not perfect and a black line appears between tiles. The rasters are in EPSG:32631, and I am also querying GeoServer's WMS in EPSG:32631, so no reprojection is done. The rasters are all 1000 pixels in widht and height, the resolution is 0.15875 (in EPSG 32631, so 0.15875 m/pix), so each raster is 158.75m in width and height. Here is an example request, and the resulting raster : WMS url : http://localhost/geoserver/dev/wms?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&FORMAT=image%2Fpng&TRANSPARENT=true&LAYERS=dev%3Ageorasters_test&CRS=EPSG%3A32631&STYLES&WIDTH=1920&HEIGHT=1349&BBOX=742405.64625%2C5087266.7415625%2C742710.44625%2C5087480.895312501 Raster : http://i.imgur.com/pE2H4QJ.png Slightly changing the bbox fixes things up (1 meter to the east) : WMS url : http://localhost/geoserver/dev/wms?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&FORMAT=image%2Fpng&TRANSPARENT=true&LAYERS=dev%3Ageorasters_test&CRS=EPSG%3A32631&STYLES&WIDTH=1920&HEIGHT=1349&BBOX=742406.64625%2C5087266.741562501%2C742711.44625%2C5087480.895312501 Raster : http://i.imgur.com/PjflMLd.png In my GeoServer layer's configuration, I have tried with "Accurate resolution computation" to true and false, to no avail (both examples above are with this setting set to true). Is there any other setting controlling the stitching mechanism ? Where could be the problem here ? In the index, or in the data ? Both are supposed to be 100% accurate, and indeed the both work without problem with another stitching library (no idea what it is exactly, it's a custom dll developed by a third party in .NET). Thanks a lot for your help ! -- Arnaud ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Geoserver-users mailing list Geoserver-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/geoserver-users
