New assessor parcel data for 2016

Opened this issue · 3 comments

Not a huge priority.

L.A. County has released 2016 parcel data. It would be worth updating buildings based on this information after some cleaning (and likely after the import).

https://data.lacounty.gov/Parcel-/Assessor-Parcels-Data-2016/7rjj-f2pv

We would need to see how many parcels have changed since 2008, there may be properties that have been subdivided and new numbers generated or tied. This may throw off the APN match since the 2008 outlines and the 2016 assessor has an 8 year gap

Yep. And I haven't seen a parcel 2016 shapefile yet.

I think this new data set can help us in two ways:

  1. Use it to create ANOTHER MapRoulette challenge that pinpoints properties with an "EffectiveYearBuilt" of 2014 or later. The latest Bing coverage I've seen is for early 2015, so it may not be comprehensive
  2. Figure out what current buildings should change and programmatically update them based on the CSVs already used in the import.
