Way demtools works, it leaves black border on 2 edges of generated images (upper and left). Solution: add margin while merging and after demtool cut border with gdal (-te and probably gdal_translate). Use enough margin to have some overlapping after cutting edges, to avoid holes. My previous mail describes in fact situation of such holes or misalignment, when two rasters doesn't meet smoothly. -- Marcin Rudowski _______________________________________________ Mapnik-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/mapnik-users
