Feature/la data #117

Closed allentran closed 4 years ago

allentran commented 4 years ago

addresses #114

Motivation and context

Speeds up pruning and parsing SM trees data (avoids two brute force N^2 computations) and some initial parsing for other LA datasets.

What I did

LA city/county, city parsers for Matt Stiles data upto Beverly Hills (starting alphabetically)
geohash street line segments and tree lat/lon points, match on same geohash while decrementing geohash digit precision (order(N) calculation)
use GeoPandas sjoin() to do a spatial join based on the predicate contains (uses a RTree to avoid doing the N^2 calculation)
