Re: [OSM-talk] Historical Data in OSM database

that historical mapping will add significantly to the OSM database size on the global scale. But if I am wrong, it will certainly add value to OSM, IMHO. (I first thought of historic: prefix, but that can be misunderstood to mean present object of historic interest.) BR/Egil Hjelmeland

Re: [OSM-talk] How inaccurate was the mapnik distance/scale marker?

I assume you are referring to the OpenLayers based slippy map at openstreetmap.org? The Openlayers 2.8 ScaleLine class has the the problem that it does not handle that the map-scale is not constant accoss the map. The slippy map uses mercators projection, where the scale increases with

Re: [OSM-talk] New Highways view in OSM Inspector

An other practical alternative: Leave the exact definition of line segments undefined (as Frederik suggests). Then tag straight ways as straight=great circle or straight=lattitude or what ever. And then tag the redundant nodes as redundant=yes. Egil Egil Hjelmeland wrote: Egil Hjelmeland
