ArcGIS REST API - ArcGIS Services

URL:http://<imageservice-url>/download
Required Capability:Catalog, Download
Version Introduced:10.0

Description

License:

As of 10.5, you must license your ArcGIS Server as an ArcGIS Image Server in order to use this resource.

The Download Rasters operation is performed on an image service resource.

The Download Rasters 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 following parameters table:

Request 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 simple 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 the Download Rasters 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, and PNG. Example: format=TIFF, format=JP2:Conversion

Example usage

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