Version 1.2.0

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 in the KNIME Hub.

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.

New nodes

• New category for Spatial clustering e.g., AZP, MSSC, MaxP, REDCAP, SCHC, SKATER
• Additional solver nodes for location analysis e.g., LSCP Solver, MCLP Solver, P-center Solver, P-median Solver (only available on Windows)
• Various other nodes such as IP to Geometry, Line Endpoints and Create Random Points

Enhancements

• Various node dialogs have been updated to show settings only if they are required or hide them in a foldable advanced section
• Geospatial View has now an image outport view e.g. to use the images in KNIME reports
• GeoFile Reader and Writer now support GeoParquet files
• Update more nodes (Area, Bounding Box, Convex Hull and Length) to provide the option to either replace or append new result column
• Spatial and Nearest Join allow users to filter out columns from input tables prior joining
• Support for custom OSRM server
• Library updates of Curl, GeoPandas, etc.

Bug fixes

• Kepler.gl view fails with multiple geometry columns
• Ensure unique coordinate reference system in Nearest Joiner node

For more information on how to update to the latest version of the Geospatial Extension see the KNIME documentation.

Version 1.1.1

This is a bug fix release that includes smaller enhancements. The major change is the update of the underlying GeoPandas library to version 0.13.2 that fixes two regressions in the library related to reading geospatial files. The enhancements are around supporting string and long columns as ID column in various nodes.
For a detailed list of all fixed bug see the release page.

Version 1.1.0

This is a summary of the changes introduced with this release of the Geospatial Extension. One major addition of this release is the support for geocoding. In addition this release adds support for drive time analysis via the new spatial network nodes. This release is only the starting point and we will continue to extend this functionality with future releases.

For more information on how to update to the latest version of the Geospatial Extension see the KNIME documentation.
This version works best with KNIME Analytics Platform version 4.7.3 or 4.7.4.

New nodes

• Spatial network nodes for drive time analysis e.g., isochrone map, drive time distance matrices​ (OSRM and Google)
• Geocoding nodes that convert points to addresses and vice versa
• Various other nodes such as Voronoi (Thiessen) Polygon, Bounding Circle and Extract Metadata such as CRS and geometry type

Enhancements

• Harmonized distance handling in various nodes that allows users to select the desired distance unit and performs projection if necessary
• Improved result column handling that allows the user to decide to overwrite the input column with the result or append a new column
• Support for user selected ID column in Spatial Weights nodes
• Extended file support allows for reading online GDB and GPKG files as well as support for KML/KMLZ files
• Spatial Join node with new options “has its center in” and “contains the center of”
• Support for date & time columns in geospatial view nodes
• Various node description improvements
• Library updates of Curl, Fiona, Folium, GeoPandas, PyPROJ, PySAL, Shapely, etc.

Bug fixes

• Missing value and special character handling in various visualization nodes
• DataApp compatibility of visualization nodes
• Fix problem when executed in read-only KNIME installations
• Fix problem when executed in offline environment
