Get a list of point cloud and/or raster features via GRiD's Web Feature Service (WFS).

Endpoint

GET <instance_url>/<instance_root>_ba/cgi-bin/gridws

Request Parameters

This is not an exhaustive list of parameters for the WFS endpoint, but represents a common use case - querying for point cloud and/or raster features by bounding box. Please refer to the WFS specification or any number of Internet tutorials for more complex use cases.

Query parameter Value
service Required. wfs
version Required. 1.1.0
request Required. getfeature
typename Optional. ms:gridws_pointcloud and/or ms:gridws_raster
bbox Optional. minx,miny,maxx,maxy

Response Format

On success, the HTTP status code in the header response is 200 OK and the response body contains the WFS response in XML format.

Example

curl -u <username> "http://gridte.rsgis.erdc.dren.mil/te_ba/cgi-bin/gridws?service=wfs&version=1.1.0&request=getfeature&typename=ms:gridws_pointcloud&bbox=62,33,62.1,33.1"
