Household Code


for about 1800 buildings two unknown keys are used:
“Household Code”
“Household Code Info By”

As you can see the keys are in clusters in Kathmandu: Overpass

For what is the information of these keys used?
Are the information essential for OSM?

Thanks & Regards. Andre

These appear to be created as part of this project:

I would contact KLL (Kathmandu Living Labs) to ask about these values (and at least ask for them to be documented). All the other tags appear to be associated with evaluating buildings at risk from earthquakes & certainly belong in OSM.

There were some surveys of households (pre-quake) around Kathmandu which did include some quasi personal information (presence or absence of internal toilet facilities), but this looks to be a post-quake restoration/resilience project.
