[merrielle]

Pull Request doc

Purpose

Addresses https://github.com/Breakthrough-Energy/PreREISE/issues/273 Adds function to create shapefiles for urban areas and rural areas for each state

What the code is doing

• Adds a function to download shapefiles from a URL, mostly copied from PostREISE
• Adds a function to take shapefiles of US states and urban areas and returns a geodataframe of both urban and rural areas.
• Adds a function to do the whole thing at once - download files, process data, and write new files.

Testing

TBD

Where to look

• It's helpful to clarify where your new code lives if you moved files around or there could be confusion/

• What files are most important?

Usage Example/Visuals

How the code can be used and/or images of any graphs, tables or other visuals (not always applicable).

Time estimate

10 mins

The code looks good and the test is great. The only thing we need to figure out before merging this is to finalize the directory of the code in the repo and the files in the blob storage. For the convenience of further discussion, here is what we have (comments in brackets open for discussion):

• Code in the repo
  • prereise/utility/generate_rural_shapefiles.py (probably we want this module sitting closely with transportation module)
  • prereise/utility/shapefile.py(this provides a general interface of downloading shapefiles from blob storage and makes perfect sense to be part of utility module)
• File on blob storage
  • state outlines: https://besciences.blob.core.windows.net/us-shapefiles/
  • urban outlines: https://besciences.blob.core.windows.net/shapefiles/urban-area-shapefiles/ (We probably want to reorganize all shapefiles currently on the blob storage as discussed during the meeting)
