Download Rasters (Operation)

URL	`http://<imageservice-url>/download`
Parent Resource	Image Service
Required Capability	Catalog,Download

Description

The download rasters operation is performed on an image service resource.

The download raster operation returns information (the file id) that can be used to download the raw raster files that are associated with a specified set of rasters in the raster catalog.

The file ids returned by this operation can be used to download individual files using the Raster File resource.

You can provide arguments to the download rasters operation as query parameters defined in the parameters table below.

Parameters

Parameter	Details
f	Description: The response format. The default response format is html. Values: html \| json
rasterIds	Description: A comma separated list of raster IDs whose files are to be downloaded Example: `rasterIds=37, 462`
geometry	Description: The geometry to apply for clipping. If specified, the selected rasters will be clipped on the server. The structure of the geometry is the same as the structure of the json geometry objects returned by the ArcGIS REST API. In addition to the JSON structures, for envelopes, you can specify the geometry with a simpler comma-separated syntax. By default the geometry is assumed to be in the spatial reference of the image service. You can specify a different spatial reference, by using the JSON structure syntax for geometries. Syntax: JSON structures: `geometryType=<geometryType>&geometry={geometry}` Envelope simple syntax: `geometryType=esriGeometryEnvelope&geometry=<xmin>,<ymin>,<xmax>,<ymax>` Examples: `geometryType=esriGeometryEnvelope&geometry={xmin: -104, ymin: 35.6, xmax: -94.32, ymax: 41}` `geometryType=esriGeometryEnvelope&geometry=-104,35.6,-94.32,41`
geometryType	Description: The type of geometry specified by the `geometry` parameter. The geometry type can be an envelope or polygon. The default geometry type is an envelope. Values: `esriGeometryPolygon \| esriGeometryEnvelope`
format	Description: The format of the rasters returned. If not specified, the rasters will be in their native format. The format applies when the clip `geometry` is also specified and the format will be honored only when the raster is clipped. New at 10.1, to force download operation to convert source images to a different format, append ":Conversion" after format string. Valid formats include: TIFF, Imagine Image, JPEG, BIL, BSQ, BIP, ENVI, JP2, GIF, BMP,PNG Example: `format=TIFF, format=JP2:Conversion`

Example Usage

Example 1: Download raster in TIFF output format, clipped to a specified envelope.

&geometryType=esriGeometryEnvelope&format=TIFF&f=html

JSON Response Syntax

{
"rasterFiles" : [ //the list of files that make up the rasters to be downloaded
  { //info pertaining to a single file
    //use this id to download the file using the Raster File resource
    "id" : "<fileId1>",
    "size" : <fileSize1>,
    //an array of IDs of rasters that include this file
    "rasterIds" : [ <rasterId11>, <rasterId12> ]
  },
  {
    "id" : "<fileId2>",
    "size" : <fileSize2>,
    "rasterIds" : [ <rasterId21>, <rasterId22> ]
  }
