I am not sure this is a good idea - adding data derived automatically from remote sensing data in an undocumented process performed by a third party without manual review and plausibility checks to the OSM database. Could you - provide any information you have on the process used for generating the height values? - provide data for a sample area to assess the robustness of the process, preferrably of a nasty area (like small buildings with varying heights and trees around)? -- Christoph Hormann http://www.imagico.de/ _______________________________________________ Imports mailing list [email protected] https://lists.openstreetmap.org/listinfo/imports
