Hi! I am using an alternate splitter (built into OSM Composer) to prepare tiles for processing with mkgmap. It works rather well, except when it comes to the splitting of polygons involved in multipolygon relations. A possible result of splitting is a large polygon split by a tile boundary into multiple smaller polygons all located in the same tile. These polygons all share the same id. The multipolygon relation is also contained in that tile. Mkgmap (r1067) processes these polygons in a weird way. Sometimes one of them is visible and the others are missing, sometimes the multipolygon relation seems to be inverted with the clearings being shown as wood and the wood missing. What is the expected strategy for splitting a polygon with multipoly relations into several parts within one tile? How does splitter handle this? Has there been some work around this area recently? bye Nop
