[Qgis-user] eliminations of seams between raster tiles?
If tiled rasters have different representations of same elevation (e.g., GTOPO tiles), the untidy seams between slightly darker/lighter representations of same level in neighbouring tiles are created. Same elevations look different across the map. Is there a possibility of layer calibration? Is there possibly some other, non-QGIS-specific way of remedying that? --- ___ Qgis-user mailing list Qgis-user@lists.qgis.org http://lists.qgis.org/cgi-bin/mailman/listinfo/qgis-user
