This blog introduces the new Least Cost Corridor tool in the Distance toolset in ArcGIS Pro 3.1. Read to learn more about its functionality.

This blog introduces the new Geomorphon Landforms tool in Spatial Analyst in ArcGIS Pro 3.1. Read to learn more about this new capability.

The Spatial Analyst extension in ArcGIS Pro 3.1 has new capabilities, as well as improvements in several key areas.  This includes an exciting new tool for identifying surface landforms. A new tool that makes finding corridors easier. Improvements for several tools in how they leverage parallel processing and GPUs for better performance.  The Suitability Modeler has some internal improvements. Many tools that perform per-cell raster mathematical operations have enhanced support for multidimensional input and output. Read on for more details on these changes.

ArcGIS Pro 3.0 makes some exciting new capabilities available to you for the Spatial Analyst extension. In the Suitability Modeler it is now easier to create more complex models, and there is an option to process large raster data efficiently with Raster Analytics. If you do water flow modelling, there are some very powerful new tools for hydrology analysis. There is a new tool to calculate a spatial relative risk surface. You can now perform zonal analysis with circular statistics.  Read on for details on these changes, and more.

For ArcGIS Pro 2.9, we made a number of improvements to the Spatial Analyst extension. Key amongst them is an exciting new capability for the Suitability Modeler. We added new functionality for calculating statistics for a moving window across multidimensional raster data. Read on for more details on these and other new and improved capabilities available with this release.

Esri's no-cost Going Places with Spatial Analysis massive open online course is for anyone who wants to gain a deeper understanding of spatial data analysis tools and workflows.

Spatial Analyst in ArcGIS Pro 2.8 offers improved Distance, Reclassification and Zonal analysis. New help content is available for Distance.

ArcGIS Pro 2.7 introduces a new tool, Surface Parameters, for analyzing the characteristics (slope, aspect, and curvature) of a surface such as an elevation surface or DEM. It is available with either a Spatial Analyst or 3D Analyst license. If you use the existing Slope, Aspect, and Curvature tools, the Surface Parameters tool is your new, better alternative with quite a few improvements. Some of these improvements are useful across most surface analysis metrics so we put them all in a single tool for a consistent experience, which also make it easier for us to add new analysis metrics in the future. This blog introduces the tool and some of its notable improvements.

Listed here are the main functional areas that have been improved in ArcGIS Pro 2.7 (December 2020) release:

1. Density
2. Distance
3. Generalization
4. Hydrology
5. Overlay
6. Segmentation and classification
7. Surface
8. Zonal
9. ArcPy

Reclassification is the process of reassigning one or more values in a raster dataset to new output values. The Reclassify tool is available in the Spatial Analyst extension in both ArcMap and ArcGIS Pro. If you are used to working with ArcMap, there are some noticeable differences in the Reclassify workflow in ArcGIS Pro. Here is a blog post about the best practices of using the Reclassify tool in ArcGIS Pro Spatial Analyst extension, especially when migrating from ArcMap.
