Hi all, Yesterday I've committed r2546 in the overview2 branch. In addition to the functionality implemented in overview_v3.patch this implements also the support of data with extended types. Please try it with the known options: --x-overview-add-polygons --x-overview-add-lines --x-overview-add-points Now I wonder what kind of further configuration we could need. The following points were discussed: 1) Allow to read data from other levels, not only the one with the lowest resolution. I tried it and I don't think this will increase quality, but it increases run time quite heavily. 2) Allow to apply filters, so that fewer objects are placed in the overview map. I think this could be implemented with a simple list like this: # filter for overview map point:type_1 point:type_2 ... point:type_n line:* polygon: This would add points with the type type_1 to type_n, all lines and no polygons. The file woud replace the --x-overview-add-xxx options. I will try to implement it in this way, please suggest changes if something else is needed. 3) Style files for the overview map I don't see how this could be used when the data is read from *.img files. 4) Read data from other sources, e.g. precompiled sea/land polygons. I don't plan to code that but I think this remains a possible option to increase quality. Open questions: 1) The current implementation adds a background polygon with type 0x4a even if option --transparent is used. I assume this is correct? 2) The background is now added as a rectangle. This could be changed so that it covers only the areas covered by the *.img files. Is this needed?
