Make WCS Layer (Data Management)
Summary
Creates a temporary raster layer from a WCS service.
Usage
-
This is one of the few tools that can accept a WCS service as an input; therefore, this tool can be used to convert a WCS service to a raster layer, which can then be used by a geoprocessing tool. The layer that is created by the tool is temporary and will not persist after the session ends unless the document is saved.
-
The input can also be a URL to a WCS server. The WCS server URL should also include the coverage and version information. If only URL is entered, the tool will automatically take the first coverage and use default version (1.0.0) to create the WCS layer.
-
The output can be the entire image service or a portion of it.
-
You can clip out a portion of the image service by choosing an output extent layer or by specifying the rectangle extent. If you choose an output extent layer, the clip extent will be based upon extent of that layer.
-
The output can be created with only a subset of the bands. This will help save on time and disk space.
Syntax
| Parameter | Explanation | Data Type |
in_wcs_coverage |
The name of the input WCS service, or the URL that references the WCS service. If a WCS server URL is used, the URL should include the coverage name and version information. If only URL is entered, the tool will automatically take the first coverage and use default version (1.0.0) to create the WCS layer. An example of a URL that includes the coverage name and version is below: http://ServerName/arcgis/services/serviceName/ImageServer/WCSServer?coverage=rasterDRGs&version=1.1.1 In this example, "http://ServerName/arcgis/services/serviceName/ImageServer/WCSServer?" is the URL. The coverage specified is "coverage=rasterDRGs", and the version is "&version=1.1.1". To get the coverage names on a WCS server, use the WCS GetCapabilities request. An example of WCS request is http://ServerName/arcgis/services/serviceName/ImageServer/WCSServer?request=getcapabilities&service=wcs | WCS Coverage; String |
out_wcs_layer |
The name of the output WCS layer. | Raster Layer |
template (Optional) |
The output extent of the WCS layer. The output extent can either be specified by defining the area to be clipped (X-Minimum, Y-Minimum, X-Maximum, and Y-Maximum) or by using the extent of an existing layer. | Extent |
band_index ID (Optional) |
Choose which bands to export for the layer. If no bands are specified, then all the bands will be used in the output. | Value Table |
