Use the new building source for the rest of LA county

maning commented 7 years ago

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

[x] Get the data from LA County GIS unit. @jschleuss
[x] Match building data to parcel using AIN as reference attribute. Should we also use the new parcel data? @jschleuss
[x] Process data into OSM XML split by census blocks @maning
[x] Prepare TM projects. @maning
[x] Announce to the world.

Data is now ready!

Some notes:

I modified the script to improve indexing during the chunking process. (https://github.com/osmlab/labuildings/pull/113)
chunk.py fails 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 .osm files 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
