census-map-consolidator
Combine Census blocks into new shapes.
Installation
$ pipenv install census-map-consolidator
Usage
Create 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 BlockConsolidator
Pass 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
