LA County will release a new building source layer from latest LARIAC. We will use this for the rest of the unimported areas within the county.
Next actions
- Get the data from LA County GIS unit. @jschleuss
- Match building data to parcel using AIN as reference attribute. Should we also use the new parcel data? @jschleuss
- Process data into OSM XML split by census blocks @maning
- Prepare TM projects. @maning
- Announce to the world.

@jschleuss bump.

Data is now ready!
Some notes:
- I modified the script to improve indexing during the chunking process. (#113)
chunk.pyfails if there are invalid geometries in the input. I deleted the invalid geometries (12 polygons) from the new building shapefile.- To speed up the process, I only refreshed the
.osmfiles for the blocks we have not yet imported (1869 in total). - There were buildings that were outside the census block poly, these buildings were not included in the current refresh.
- I prepared a short diary to update the community about the recent refresh. Can someone review? https://gist.github.com/maning/c27d0df57a362c486033530167f2b794
