Run with
python process.py
It will download all source data necessary.
GeoJSON files for all US Zip Codes
I got the data from the US Census Zip Code Tabulation Areas page.
Since the data does not have any city, state, or centroid information, I added in data from the Geonames.org free postal code data page.
I created a shell script that can be used to pull down all the data:
$ ./get_source_data.sh
Since I needed all the U.S. territories, I had to pull those down and concatenate them to the US.txt file.
Run the process.py command:
$ python process.py
The resulting data will be written into the data directory.
