# Reshaper

Project description

# Reshaper

Splits and recombines shapefiles based on lat-long data.

## Installation

conda install -c conda-forge gdal pip install reshaper

## Usage

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.

## Release

Change the “version” in setup.py to “x.x.x”, commit and tag:

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

To [distribute](https://packaging.python.org/en/latest/distributing.html), run:

rm -rf build dist flake8 . python setup.py test python setup.py sdist bdist_wheel –universal twine upload dist/*
