If mkgmap throws out<br>> a warning about too many nodes in a tile, I let splitter create a new<br>> areas.list for the region and I can continue.<br>> <br>> In the new workflow I then have to adjust the script, which copies the<br>> multiple used tiles.<br>> <br>> It would be very helpful, if splitter can do the copying of tiles.<br>> <br>> Splitter detects overlapping areas in areas.list and handles these<br>> regions as a own polygon and is writing tiles for each map, which<br>> touches the overlapping area.<br>> <br>> So for example, if a split a map of Hessen (10000000) and a map of<br>> Germany (11000000), splitter will use a polygon of Germany with a hole<br>> at the place where Hessen-poly-file has a coverage and Hessen-polygon.<br>> <br>> So the resulting areas.list could looks like:<br>> <br>> 11000001;10000001: ....<br>> 11000002: ....<br>> <br>> So splitter is able to write the data of a tile in Hessen to the map<br>> of Hessen and to the map of Germany.<br>> <br>> Maybe such a system is a better and more robust solution then handling<br>> overlapping tiles. But I don't want to made you code that only for me.<br>> <br>> Henning<br>> <br>> <br>> Am 11.05.2014 10:49, schrieb Gerd Petermann:<br>> > Hi Henning,<br>> > <br>> > can you describe what flexibility you are loosing?
