Hi Martin, You can view the alignment to bing imagery via the 'edit' mode of openstreetmap: http://www.openstreetmap.org/edit?editor=potlatch2&changeset=19821285#map=19/-38.29507/144.39249
> the original file is spot on To give you a little more context, the OSM community is a bit wary of large scale imports - it's quite easy for the data to grow stale, and minor errors to accrue. As a result, the OSM process tends to place highest trust on physical, on the ground observations & multiple GPS traces, particularly of the road network. Can you go into a little bit of detail around the processes you've used to get to a high level of trust in the data? The data set does mention LiDAR + Photogammetry, but I'm sure we'd all be quite interested to know a bit more On Mon, Feb 10, 2014 at 3:49 PM, Martin von Wyss <[email protected]>wrote: > Hello Daniel et al.
