Understanding analysis in Portal for ArcGIS

You can perform several types of analysis in your portal. These types of analysis can be categorized based on the data used in the analysis. If you plan to perform analysis on data that contains features or tabular data, you will perform feature analysis. If your data is in raster format, you will perform raster analysis. The types of analysis you can perform also depends on the ArcGIS components your administrator has installed. See each toolset's description below for details.

Analysis tools can be used in the portal map viewer, ArcGIS Pro, the ArcGIS Python API, and the ArcGIS REST API. In the portal map viewer, you can access the tools by clicking the Analysis button and choosing the type of analysis you want to perform. With the ArcGIS Python API, you can access the tools through the tools module. To learn more, see the tools module documentation and the sample notebooks.To use the tools via the ArcGIS REST API, you will access the tasks from the corresponding ArcGIS Server service that powers the toolset. See the ArcGIS REST API documentation for details.

Feature analysis

Feature analysis can be performed through the portal with two different toolsets: the standard spatial analysis tools and the GeoAnalytics Tools provided with ArcGIS GeoAnalytics Server. These tools can be accessed through the portal map viewer under Standard Tools for the spatial analysis tools and GeoAnalytics Tools for the GeoAnalytics Tools tools. See below for a description of the standard spatial analysis and big data analysis toolsets. See also Standard and GeoAnalytics Tools feature analysis comparison for an in-depth discussion of the differences between the types of analysis and the tools included in the toolsets.

Spatial analysis tools

These tools can be used to perform common analytical functions such as finding hotspots, locating streets and addresses, finding a place, routing, or accessing a geodatabase. By performing analysis, you can answer questions and make important decisions using more than visual analysis. The spatial analysis tools can be used by following the steps in Perform Analysis. This topic also includes an overview of each tool in the toolset.

GeoAnalytics Tools

These tools can be used to perform analytical functions that analyze patterns and aggregate data in the context of both space and time. Your analysis can be performed more quickly and with larger quantities of data than could previously be computed on a single machine. The GeoAnalytics Tools tools can be used by following the steps in Perform big data analysis. This topic also includes an overview of each tool in the toolset.

Raster analysis

The raster analysis tools are used to analyze and process imagery and raster datasets such as multispectral satellite and aerial imagery, elevation, scientific and classified datasets. The tools can analyze imagery based on algorithms, analyze spatial patterns, analyze terrain to derive surfaces, summarize data, and manage data. These tools manage and perform scalable raster analysis and image processing on large volumes of raster data from multiple sources. When you analyze your data, you are able perform robust raster analysis and processing using a large suite of raster functions. Create and execute spatial analysis models and image processing chains while leveraging distributed processing and storage. For more information, see Perform raster analysis.
