[mkgmap-dev] Address & city country name assignment.From Robert Vollmert rvollmert-lists at gmx.net on Wed Feb 16 13:28:31 GMT 2011
[This is not particularly in reply to Dermot.] First off, congratulations on the progress that you've been making with respect to search. My suggestion would be to move region (country, city) detection into a preprocessing step, outside of mkgmap. That is, some other tool preprocesses and normalizes the osm data and assigns consistent is_in tags. Then mkgmap looks only at the is_in tags. The same approach could be used for coast line and multipolygon handling: A preprocessor would fix up or delete broken multipolygons and standardize tagging (on outer way, on the relation, etc.) Ideally, there'd be planet dumps and extracts or a read-only API that delivered such normalized data, as this would be useful to most consumers of OSM data. Other things that could be done: - Normalize footway/cycleway/path. - Assign maxspeed tags based on inside/outside built up area. - ... I realize this is quite far away, and going just part of the way would make mkgmap harder to use (need to run a bunch of tools on the extract before compiling the map). So I'm not saying anyone should do this, just trying to suggest an alternative approach. Cheers Robert
