[HOT] OSM Damage Assessment
Hello HOT community, I am currently doing a research where I am validating and comparing different types of damage assessments of Nepal EQ - UNOSAT/Copernicus, Tomnod, Ushahidi (a special case) and I would like OSM damage assessment to be researched as well. I would have therefore some questions: 1. What everything is being mapped in terms of damage assessment? I have noticed landslides and damaged buildings. 2. In case of buildings, is there any classification of the level of damage being made (e.g. EMS-98 scale)? 3. How is the progress of the damage assessment so far? Do you think that the current status of DA is already enough good to be used? 4. How can I download all the damage assessment data in one package? I noticed the links for 30 minutes updates of the data, but that does not (as far as I know) include DA data. I would like to thank you in advance for any answer. Wish you all a great day, Michal. -- Michal Bodnár, M.Eng.
