[OSM-talk-be] LiDAR

[joost schouppe]

Marc, I think you might be thinking of SK53's work. I think he wrote
several posts about how lidar can help identify buildings, e.g. here:
http://sk53-osm.blogspot.be/2016/05/bristol-new-brighton-buildings-from.html

There is quite a bit of lidar altitude data available for Flanders, both
raw and processed. The 3D GRB for example was based on that data. See:
http://www.geopunt.be/catalogus/search?facet=catalog&q=lidar

Building heights do have a wiki page:
https://wiki.openstreetmap.org/wiki/Key:height#Height_of_buildings
But then a rule of thumb is we don't map that which can easily be
automatically generated, so I don't really see the point of using something
like 3D GRB for OSM.

An interesting thing about raw lidar data is that it can help identify
trees, as they have a special kind of pattern in the data. So you could use
processed data to identify potentially missing landuse=forest / tree rows /
trees.
