Description

Bounding box-based catalog search of topography datasets hosted by OpenTopography.

Parameters (9)

detail (boolean, query, optional)

Show detailed metadata (optional). Defaults is false and shows specific metadata information.

include_federated (boolean, query, optional)

Include federated datasets available via OpenTopography (e.g. USGS 3DEP Catalog)

maxx (number, query, optional)

WGS 84 bounding box east coordinates. Required if polygon parameter is not provided.

Constraints: {'minimum': -180, 'maximum': 180}

maxy (number, query, optional)

WGS 84 bounding box north coordinates. Required if polygon parameter is not provided.

Constraints: {'minimum': -90, 'maximum': 90}

minx (number, query, optional)

WGS 84 bounding box west coordinates. Required if polygon parameter is not provided.

Constraints: {'minimum': -180, 'maximum': 180}

miny (number, query, optional)

WGS 84 bounding box south coordinates. Required if polygon parameter is not provided.

Constraints: {'minimum': -90, 'maximum': 90}

outputFormat (string, query, optional, default: json)

Output Format (optional) - Defaults to json if parameter is not provided. Other available formats - xml

Constraints: {'enum': ['json', 'xml']}

polygon (string, query, optional)

A string of points to make up a polygon (WKT format). The first and last points should match to complete the polygonal shape. If this parameter is provided, the bounding box parameters: minx, miny, maxx, and maxy will be ignored. Example: -117.5,32.5,-117.5,33.1,-116.7,33.1,-116.7,32.5,-117.0,32.3,-117.5,32.5

productFormat (string, query, optional)

Data product Format (optional) - Point Cloud or Raster. Defaults to all data products

Constraints: {'enum': ['PointCloud', 'Raster']}
