[OSM-talk-be] LiDAR

[Julien Minet]

Indeed, no elevation data in OSM except the ele=* tag. However, I'm using a
lot this hillshade layer from the Région Wallonne
<http://geoservices.wallonie.be/arcgis/services/RELIEF/WALLONIE_MNT_2013_2014_HILLSHADE/MapServer/WMSServer?request=GetCapabilities&service=WMS>
in JOSM, which is very nice to map streams, tracks and other features in
forested areas. I think this layer is derived from LIDAR. To me, that's a
way to use LIDAR data in OSM.
