Hi OSM mappers, As most of you are probably aware, we had a severe earthquake in Christchurch, New Zealand this week, killing over 100 people and demolishing or damaging hundreds, possibly thousands of the following: buildings roads bridges water mains electricity supplies sewage drains other major infrastructure. NZ mappers have been discussing how they can help, and we have decided it would be useful to trace as many of these pieces of infrastructure as possible in the affected area. Christchurch has very good Bing imagery taken last year, allowing pre-quake items to be traced quite accurately. High quality post-earthquake imagery will be available in the next 24-48 hours [1], to enable further tracing [2], to show the current situation. Both pre- and post-quake tracing are requested, to allow appraisal of the differences caused by the earthquake. If anyone can help, please head over to http://www.openstreetmap.org/?lat=-43.563&lon=172.7&zoom=11 and lend a hand. Tracing of altered natural features would also be useful, although infrastructure is of more importance for the moment Any further questions, please ask. [1] we're not sure where or how yet - perhaps someone can assist here also, getting the images into Potlatch/JOSM/etc.? [2] with appropriate tags for damaged/re-arranged items - would the likes of 'date_on' be appropriate here? please advise if you can suggest the most suitable tags to use thanks, -- robin http://tangleball.org.nz/ - Auckland's Creative Space http://openstreetmap.org.nz/ - Open Street Map New Zealand http://bumblepuppy.org/blog/ _______________________________________________ talk mailing list t...@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk _______________________________________________ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
