Some thoughts regarding landslides in OSM, as we may be dealing with them in upcoming days. It looks like there are some standards folks have used in the past that may apply, as in the following:
http://wiki.openstreetmap.org/wiki/JA:2014_Tanba_landslide original: 災害関連タグリスト 土砂災害 (Disaster related tags list Sediment disaster) hazard_prone = yes hazard_type = landslide landuse = brownfield natural = bare_rock surface = dirt source = xxxx Another resource mentioned their impact on roads: https://help.openstreetmap.org/questions/34076/tagging-highway-blocked-by-landslide And another appears to emphasize future hazards: http://wiki.openstreetmap.org/wiki/OpenHazardMap I propose an approach like this*: hazard_type = landslide landuse = brownfield area = scarp (for bare area where slide originates) area = deposit (for area where material comes to rest) barrier = deposit(?) or scarp (?) when path road or stream appears blocked adding these tags as per earlier instructions may be useful also: damage:event=nepal_earthquake_2015 source=DigitalGlobe , 2015-05-03 > rationale for specificity with barrier and areas is that scarp may be impassable for a much longer time than the deposition area. Also, fresh scarps are likely the most visible feature, as an example, a highly probable earthquake related scarp is visible in the DG imagery near 27.795 85.7786. I can't confidently make out where the deposit is, though. Nor can I tell if it blocks any paths or roads. Scarp appears little used in OSM, so it would be easy to pull out recent additions once people start actively mapping them -- and it is such a useful term. Many examples of mapped slides here: http://www.oregongeology.org/slido/index.html Cheers, John *experience level: noob
