stuartlynn / tile_pop_prediction

Experiment to see if population can be predicted from map tiles

Method

Grab tiles from CartoDB and calculate population in those tiles from the census:

SELECT CDB_OVERLAP_SUM(
        ST_TRANSFORM(
          CDB_XYZ_Extent(603,769,11), 4326),
          'us_census_acs2013_5yr_census_tract_copy ',
          'total_pop',
          'stuartlynn')

where CDB_OVERLAP_SUM can be found here : https://github.com/CartoDB/crankshaft/blob/master/pg/sql/0.0.1/03_overlap_sum.sql Download tiles to ./tiles

Train NN to predict the population off the tile set using keras.
