[OSM-talk-be] Wallonia : new dataset : elevation data
Hi, I have two news with SPW / Wallonia, I will separate those news into two threads. Wallonia has published this week a brand new digital elevation model : http://geoportail.wallonie.be/cms/render/live/en/sites/geoportail/home/geocatalogue.html?mdUUID=1365808b-36f9-4cd3-8ca7-c5aafbe93170 This was calculated with lidar, with a vertical precision of 12 cm, and around 1 dot/meter sq. What about elevation ? Osm is in 2d, we do not gather elevation data ! I know about that; but what might be very intersting is that there is also a [modèle numérique de surface / digital surface model.] This allow us to see buildings and trees very clearly. Example here, in Namur : http://geoportail.wallonie.be/WalOnMap/#BBOX=185392.55536360716,185807.6874438713,128187.20688341379,128421.09901786472#MSS=MNS2013,true,100,0:true|;#BMS=FDP|100;FDPANNO|100;#TOC=MNS2013 Where shadows does not allow to see clearly where are the building border, the DSM might help us. It also hide unuseful details. Trees are also visible. And we might calculate the building height. The SPW might us know that we are allowed to use their data for osm :-) What do you think ?

Very nice news. I didn't get the meaning of your sentence : "The SPW might us know that we are allowed to use their data for osm ", can we already use it in OSM ?

Yes, we are allowed to use those date to draw objects in OSM database. Julien Fastré ___ Talk-be mailing list Talk-be@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-be
