I can see this message: Exact map coverage read from input file(s) is (46.7038893699646,-20.071227550506592) to (60.539002418518066,28.109700679779053) Exact map coverage after applying bounding box of polygon-file is (47.26541519165039,6.1527299880981445) to (55.147762298583984,15.05077600479126) Exact map coverage is (47.26541519165039,6.1527299880981445) to (55.147762298583984,15.05077600479126) But calculated areas are exactly the same as in original version: Area 63240012 covers (46.669921875,-20.0830078125) to (60.029296875,7.646484375) and contains 41151962 nodes (84 %) I have attached logs from both versions. -- Best regards, Andrzej _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
