Introduction

Density analysis root resource, density analysis can calculate specified point and line object density around every imported pixel. Density analysis, to some extent, is to separate point and line object measurement value on surface, to distribute each point and line object measurement in the entire research area, and calculate the density value in every raster pixel.

Supported Methods:

GET: Get the density analysis methods supported by the current dataset.
HEAD: Check whether the datasetDensityAnalyst resource exists. or to access the datasetDensityAnalyst resource.

Supported output formats: rjson, json, html, xml.

Resource hierarchy

HTTP request methods

Implement the HTTP request on the following URI, where supermapiserver is the server name, with rjson being the output format.

http://supermapiserver:8090/iserver/services/spatialanalyst-sample/restjsr/spatialanalyst/datasets/SamplesP%40Interpolation/densityanalyst.rjson

GET request

Gets the density analysis methods supported by the current dataset.

Response structure

Returns the child resource information list of density analysis methods supported by the current dataset. The information in each child resource are as follows.

Field	Type	Description
name	string	The name of the child resource.
path	string	The URI of the child resource.
resourceConfigID	string	The ID of the resource configuration file.
resourceType	ResourceType	The resource type.
supportedMediaTypes	string[]	The supported media types.

Response example

The returned rjson format representation after implementing the GET request on the datasetDensityAnalyst resource http://localhost:8090/iserver/services/spatialanalyst-sample/restjsr/spatialanalyst/datasets/SamplesP@Interpolation/densityanalyst.rjson is as follows:

[{

"name": "kernelDensity",

"path": "http://localhost:8090/iserver/services/spatialanalyst-sample/restjsr/spatialanalyst/datasets/SamplesP@Interpolation/densityanalyst/kernel",

"resourceConfigID": null,

"resourceType": null,

"supportedMediaTypes": null

}]

HEAD request

Asks for the response identical to the one that would correspond to a GET request, but without the response body. This is useful for retrieving meta-information written in response headers, without having to transport the entire content. The meta-information includes the media-type, content-encoding, transfer-encoding, content-length, etc.

HEAD request can be used to check if the datasetDensityAnalyst resource exists, or if the datasetDensityAnalyst resource can be accessed by clients. It can also determine if the datasetDensityAnalyst resource supports an output format <format> if performed on a URI with .<format> included.
