Open Workflow-based GIS tool: Geospatial Analytics Extension for KNIME
Updated by Oct 16,2023
We’re excited to announce the 1.2 release of the Geospatial Extension which now supports the experiments detailed in the first KNIME workbook for GIS: “Computational Methods and GIS Applications in Social Science – Lab Manual ” by Lingbo Liu and Fahui Wang. For a deeper understanding and broader applications, users are encouraged to refer to the main text with case studies implemented in ArcGIS Pro: “Computational Methods and GIS Applications in Social Science, 3rd Edition” authored by Fahui Wang and Lingbo Liu. The workflows for the Lab Manual are available in the Geospatial Space 9 in the KNIME Hub 3.
The major addition in this release is the support for spatial clustering. In addition, this release adds several new solver nodes for location analysis. We have further improved the usability of several nodes by moving advanced settings into a foldable advanced section or hide settings that are not needed for the current situation.
This version requires KNIME Analytics Platform version 5.1.1 or later.
GitHub Link for Geospatial Analytics Extension
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.
Installation
The extension can be installed via the KNIME Hub by dragging and doping or installed like any other KNIME extension via the KNIME Extension Manager.
If you want to test the latest version you can follow the instructions in the Setup section of the Contribution guide.
Usage
Here are some examples of workflows that use the extension. You can also find some videos on the YouTube channel.
