Street geometry processing toolkit

neatnet: Street Geometry Processing Toolkit

Introduction

neatnet offers a set of tools pre-processing of street network geometry aimed at its simplification. This typically means removal of dual carrieageways, roundabouts and similar transportation-focused geometries and their replacement with a new geometry representing the street space via its centerline. The resulting geometry shall be closer to a morphological representation of space than the original source, that is typically drawn with transportation in mind (e.g. OpenStreetMap).

Examples

A fully-reproducible example can be found in the User Guide.

import neatnet

simplified = neatnet.neatify(gdf)

Installing

You can install neatnet from PyPI or from conda-forge using the tool of your choice:

pip install neatnet

Or (recommended):

conda install neatnet -c conda-forge

Contribution

While we consider the API stable, the project is young and may be evolving fast. All contributions are very welcome, see our guidelines in CONTRIBUTING.md.
