kml2geojson

kml2geojson is a Python 3.8+ package to convert KML files to GeoJSON files. Most of its code is a translation into Python of the Node.js package togeojson, but kml2geojson also adds the following features.

• Preserve KML object styling, such as color and opacity
• Optionally create a style dictionary cataloging all the KML styles used
• Optionally create several GeoJSON FeatureCollections, one for each KML folder present

Installation

Create a Python 3.8+ virtual environment and run poetry add kml2geojson.

Usage

Use as a library or from the command line. For instructions on the latter, type k2g --help.
