Overwrite result layer

Option to overwrite existing layers. When checked, if a layer with the same name already exists within your contents, it will be overwritten.

• Checked—If a layer with the same name already exists within your contents, it will be overwritten. The output will have the same coordinate system as the input.
• Unchecked—If the result layer name provided already exists, an error will occur and the result layer must be renamed before tool can be executed. This is the default.

Close analysis widget after running analysis

Option to keep the analysis dialog open and enabled while the tool is processing. This setting will allow you easily make modifications to your analysis parameters while the previous analysis job continues to run. Analysis is an iterative process and by keeping the tool dialog open, it allows you to easily make parameter changes and rerun your analysis.

• Checked—The analysis tool window will close and focus will be returned to the table of contents. This is the default
• Unchecked—The analysis tool window will remain open and enabled.

Store analysis results as hosted feature layers

Option to specify whether the result layer created from your analysis will be a feature collection or a hosted feature layer.

• Checked—The results of your analysis will create a hosted feature layer and an item will be created in your contents. This is the default.
• Unchecked—The results of your analysis will create a feature collection.

Output coordinate system

Environment setting for raster analysis used to define the coordinate system of the result layer.

• Same as Input—The result of your analysis will be in the same coordinate system as the input. This is the default.
• As specified—Choose the coordinate system for the results of your analysis. When this option is selected, click the globe icon to select from a list of known coordinate systems, or add the spatial reference WKID in the box provided.
• Layer <name>—Choose an existing layer in your web map that will be used to determine the coordinate system of the result of your analysis.

Processing coordinate system

Environment setting for GeoAnalytics used to determine the coordinate system your analysis will use during execution of the analysis.

For GeoAnalytics, some analysis requires that processing be executed in a projected coordinate system. Any tool that has implemented binning of data or linear units requires a projected coordinate system.

• Same as input—Your analysis will be processed in the same coordinate system as the input. This is the default.
• As specified—Choose the coordinate system to process your analysis. When this option is selected, click the globe icon to select from a list of known projected coordinate systems, or add the spatial reference WKID in the box provided.
• Layer <name>—Choose an existing layer from your web map. The coordinate system of the layer chosen will be used to determine the coordinate system that will be used to process your analysis.

Extent

Environment setting used to determine the extent or boundary that will be used during execution of the analysis. All input features that are completely within or that intersect the specified extent will be used in the analysis.

• Default—Use the extent provided by the tool.
• As specified—Manually enter the coordinates to define the extent.
• Layer <name>—Choose an existing layer from your web map. The spatial extent of the layer chosen will be used to determine the extent used to process your analysis.

Snap Raster

When performing raster analysis, setting the Snap Raster environment will adjust the extent of the output raster layer so it matches the cell alignment of the specified Snap Raster layer.

Cell Size

When performing raster analysis, this environment sets the cell size or resolution that will be used to create the output raster layer. The default output resolution is determined by the largest cell size of the input raster layer.

• Minimum of Inputs—Use the smallest cell size of all input layers.
• Maximum of Inputs—Use the largest cell size of all input layers. This is the default.
• As specified—Specify a numeric value to set the cell size. If this is selected, the default value is 1.
• Layer <name>—Set the cell size to the raster layer chosen.

Mask

When performing raster analysis, use the Mask environment to specify a layer that will be used to define your area of interest. Only those cells that fall within the analysis mask will be considered in the analysis operation.

• The mask can be either a raster or a feature layer.
• If the analysis mask is a raster, all cells that have a value will be considered to define the mask. Cells in a mask raster that are NoData will be considered to be outside the mask and will be NoData in the analysis result layer.
• If the analysis mask is a feature layer, it will be internally converted to a raster on execution. For this reason, take care to ensure that and are set appropriately for your analysis.

ArcGIS Data Store

GeoAnalytic results are stored in an ArcGIS Data Store and exposed as a feature layer in Portal for ArcGIS. In most cases, results should be stored in a spatiotemporal data store. This is the default. The following are reasons why you may want to store results in a relational data store:

• To use your results in portal-to-portal collaboration
• To enable sync capabilities with your results

You should not use a relational data store if you expect your GeoAnalytics results to increase and want to take advantage of the spatiotemporal big data store's capabilities to handle large amounts of data.
