(Required)

The feature layer used to calculate density. The dataset can either be point, line, or polygon features.

Syntax: This parameter can be specified as a URL to a feature service layer with an optional filter to select specific features, or a feature collection.

Input feature examples:

//Feature layer url
{"url": <feature service layer url>, "filter": <where clause>}

//Feature collection
"inputPointOrLineFeatures":{"layerDefinition": {}, "featureSet": {}, "filter": <where clause>}

(Required)

The name of the output image service that will be created.

You can specify the name, or you can create an empty service using Portal Admin Sharing API and use the return JSON object as input to this parameter.

Syntax: A JSON object describes the name of the output or the output raster.

Output name example:

"outputName":{"serviceProperties":{"name":"testrasteranalysis"}}

Output raster examples:

//Output portal item:
"outputName":{"itemId": <portal item id>}

//Output url:
"outputName":{"url": <image service url}

//Output raster layer service:
"outputName":{"serviceProperties":
  {"name":"testrasteranalysis",
    "serviceUrl":"https://<server name>/server/rest/services/Hosted/testrasteranalysis/ImageServer"},
  "itemProperties":{"itemId":"8cfbd3ec25584d0d8f4ed23b8ff7c43b","folderId":"sdfwerfbd3ec25584d0d8f4"}
}

Specifies the number of incidents at each location. The domain can either be an integer or float field.

Syntax: A string that represents a field name. If each point represents a single incident, do not provide a count field.

"countField": "myCountField"

The size of the neighborhood within which to calculate the density.

For example, if you provide a search distance of 1800 meters, the density of any location in the output layer is calculated based on features that are within 1800 meters of the location. Any location that does not have any incidents within 1800 meters will receive a density value of zero.

If no distance is provided, a default will be calculated that is based on the locations of the input features and the values in the count field (if a count field is provided).

Syntax: A linear unit specifying the distance and units.

Supported units: Meters | Kilometers | Feet | Miles | FeetInt | MilesInt

"searchDistance" : {"distance":"60","units":"Meters"}

The desired output units of the density values.

Supported units: SQUARE_KILOMETERS | SQUARE_MILES

The default is based on the units specified in your profile. If the units are set to Metric, the default is SQUARE_KILOMETERS. If your profile is set to US Standard, the default is SQUARE_MILES.

{"outputAreaUnits" : "SQUARE_KILOMETERS"}

The cell size that will be used for the output raster.

Supported units: Meters | Kilometers | Feet | Miles | FeetInt | MilesInt

The default value for this parameter is the same as the analysis environment.

"outputCellSize": {distance":"60","units":"Meters"}

The dataset that defines the barriers. The barriers can be a feature layer of polyline or polygon features.

Syntax: This parameter can be specified as a URL to a feature service layer with an optional filter to select specific features, or a feature collection.

//Feature layer url
{"url": <feature service layer url>, "filter": <where clause>}

//Feature collection
"inBarriers":{"layerDefinition": {}, "featureSet": {}, "filter": <where clause>}

Contains additional settings that affect task processing. This task has the following settings:

• Extent (extent)—A bounding box that defines the analysis area.
• Output Spatial Reference (outSR)—The output raster will be projected into the output spatial reference.
• Snap Raster (snapRaster)—The output raster will have its cells aligned with the specified snap raster.
• Cell Size (cellSize)—The output raster will have the resolution specified by cell size.
• Mask (mask)—Only cells that fall within the analysis mask will be considered in the operation.

The response format. The default response format is html.

Values: html | json | pjson
