Geospatial Analytics Extension for KNIME

This repository is the home of the Geospatial Analytics Extension for KNIME Analytics Platform. The extension provides a set of nodes for spatial data analysis and visualization.

The extension is developed by the Center for Geographic Analysis at Harvard University and KNIME as part of a two-year project of the Spatiotemporal Innovation Center. The goal of the collaboration is to develop KNIME Analytics Platform extensions and best-practice workflows to provide a consistent and compatible platform for spatial data analysis across disciplines.

The extension is mainly based on the GeoPandas library and the PySAL library. The data types are defined in the KNIME - Geospatial Data Types extension.
