ArcGIS Spatial Analyst Extension Geospatial Tools

Description

ArcGIS Spatial Analyst is an extension for ArcGIS Pro that provides advanced spatial modeling and analysis capabilities for both raster and feature data. It helps with modeling terrains, performing hydrologic analysis, finding suitable locations and routes, and discovering spatial patterns.

The Spatial Analyst extension for ArcGIS Pro provides a suite of tools and capabilities for performing comprehensive, raster-based spatial analysis. With this extension, you can employ a wide range of data formats to combine datasets, interpret new data, and perform complex raster operations. Examples of the analysis that you can do with Spatial Analyst include terrain analysis, surface modeling, surface interpolation, suitability modeling, hydrological analysis, statistical analysis, and image classification.

The following are brief descriptions of the main components of Spatial Analyst:

• A common way to access Spatial Analyst functionality is with the  tools. This rich environment allows you to organize and execute the tools necessary to complete your analytic tasks, and it provides a mechanism to automate, document, and share your workflows.

  In the , you can perform Spatial Analyst operations in the following ways:

  • Run individual
  • Combine tools with  to automate workflows and create spatial models
  • Automate workflows and create new tools with

   

•  is a powerful algebraic language for performing raster analysis. Map Algebra is fully integrated into the Python environment.

  There is also a  tool that allows you to easily create Map Algebra expressions in a tool dialog or in ModelBuilder.

• Many of the analytical operations are also available as . Local operations are applied directly to the pixels from a raster dataset that are currently being displayed in the map. This allows the calculations to be performed on the fly, giving an immediate response as you zoom and pan around your data. Certain types of operations are more complicated or must be performed across more cells than are currently displayed to give meaningful results. These are called .

• The  is a dynamic, exploratory environment of interacting panes, plots, and maps that help you create a better suitability model.

Following is further discussion of each of these components of the Spatial Analyst experience in ArcGIS Pro.
