Here's a general idea what we're doing in Lithuania. Government has datasets d1, d2... dn. OSM has one big dataset O which could be split into datasets o1, o2... om. We take datasets dx and oy which could be mapped (have similar data, like placenames, roads, lakes, rivers, etc.) Automated importing to either direction is impossible (or not wanted by both sides). Government datasets need strict accountability (sources, documents) and responsibility. OSM has different data and simply overwriting it with government data would be bad in a lot of ways. So the way integration between OSM and government (and actually any other datasets) is done is by synchronisation - checking for differences and taking action (mostly manual) on them on both datasets. By doing a comparison both government and OSM datasets are improved. The point here is that government datasets usually use official (document) source to update data. OSM uses local knowledge to update data. None of these methods are perfect, so synchronisation/comparison helps to get most/best of both. (as a separate note: here comes OSM strength that everything is in one layer - it is much harder to have a road going through a lake or building or having a street A with address B along it. Government datasets are usually separate and controlled by different institutions, so doing such topology checks is much more difficult there) For this to work government must open datasets and appoint a working contact point where information about problems in government dataset could be sent and there this information is ACTUALLY used and feedback given. -- Tomas _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
