Reshaper

Splits and recombines shapefiles based on lat-long data.

Installation

pip install reshaper

To split a state map based on a branch list, use:

reshaper state.shp branch.csv output.shp --id branchname --lat lat_col --lng lng_col

This takes 3 arguments:

state.shp: path to the original shapefile
branch.csv: path to the CSV file with points data. The output shapefile will have one shape per row of this file
output.shp: path to the output shapefile

branch.csv should have at least these 3 indicators:

--id branchname: indicates that the branchname column holds the branch identifier. The values in this column must be unique
--lat lat_col: the lat_col column holds the latitude in degrees
--lng lng_col: the lng_col column holds the longitude in degrees

The program splits and re-combines shapes based the following logic:

If a state does not have a branch, assign it fully to the nearest branch
If a state has only one branch, assign it fully to that branch
If a state has multiple branches, split it between the branches and assign each broken state to the respective branch

The output shapefile has an id column holding the --id value.

git commit . -m"Describe features / bug fixes"
git tag -a vx.x.x -m"one-line summary of release"

rm -rf build dist
