Combine Census blocks into new shapes.
pipenv install census-map-consolidatorCreate a list of Census block GEOIDs. That can be simple like this:
your_block_list = ["060371976001008", "060371976001009"]Or read in from a file like this:
with open("test_data/dtla.csv", "r") as f:
your_block_list = f.read().splitlines()Import our class.
from census_map_consolidator import BlockConsolidatorPass in the block list as arguments.
c = BlockConsolidator(*your_block_list)Consolidate the blocks into a single shape. This can take a minute. Big shapefiles have to be downloaded.
c.consolidate()Write out the new shape. You can do GeoJSON.
c.write("./your-new-shape.geojson")Or shapefiles.
c.write("./your-new-shape.shp")That's it. You can inspect your work however you like. But geojsonio is handy.
geojsonio < your-new-shape.geojson
