Tagging earthquake vulnerabilities of buildings: Developing world

Michael Patrick

Near Kathmandu, there's a series of tags relating to surveys of quake
status of buildings. Would someone be interested in helping working out a proper tag scheme, and proposing it to whatever groups are doing this data collection?

The intent is great, the execution... um...

The execution is in alignment with their intent.

Their scheme actually appears to be a localized and even more simplified subset of ISO 28841:2013 "Guidelines for simplified seismic assessment and rehabilitation of concrete buildings": ( ... The rules of design as set forth in ISO 28841:2013 are simplifications of more elaborate requirements. ... can be used as an alternative to the development of a building code, or equivalent document in countries where no national design codes are available by themselves, ), or something similar.

Their tagging system is derived from the cumulative efforts of thousands of specialists ( seismologists, structural engineers, architects, etc.) over decades with consultations of forensic experts with relief teams, created by obviously people knowledgeable of local conditions and needs. In combination with information not is OSM ( like the severity and location of an actual event ), it would have great utility for triage and prioritization of rescue and relief efforts. Or non-emergency upgrade programs.

It looks long because of the manner of presentation and the duplications caused by case insensitivity. In practice through an interface, it probably isn't all that daunting to someone doing rapid field collection.

If there is a desire for OSM to grow by embracing communities of use, those communities are going to arrive with their own ontologies and classifications, and I doubt ('know') they are going sacrifice what they regard as essential. And these groups will tend be a 'keystone community' in an particular locality, and cause a lot of the other regular OSM geometry in an area to be created and maintained, and their local partnerships will create additional efforts and mappers.

IMHO, as long as they are operating in their area, I'd leave them alone and see how it evolves. If it really is to complicated, they will soon figure it out themselves. Most I'd do is ask them to put up a wikipage explaining the intent and application.

The key names are mostly misspelled!
The data values are standardized.
Have a read through the tag list in the initial email.
