Description

Access U.S. Geological Survey 3DEP raster datasets including 1m, 1/3 arc-second (10m), 1 arc-second (30m) Digital Elevation Model. Note: 1m DEM is currently restricted to academic users. Requests are limited to 225,000 km² for USGS30m, 25,000 km² for USGS10m, 250 km² for USGS1m data. This API service relies on USGS resources. OpenTopography does not control the availability or performance of this service.

Parameters (7)

API_Key (string, query, required, default: demoapikeyot2022)

USGS 3DEP 1m raster dataset is currently restricted to academic users. Academic users can request access to these data via the OpenTopography portal. Non-academic users can enquire about an enterprise API key by emailing info@opentopography.org. See OpenTopography Terms of Use for more information on appropriate use of the API.

datasetName (string, query, required)

USGS 3DEP raster: USGS1m, USGS10m, USGS30m

Constraints: {'enum': ['USGS30m', 'USGS10m', 'USGS1m']}

east (number, query, required)

WGS 84 bounding box east coordinates

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

north (number, query, required)

WGS 84 bounding box north coordinates

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

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

Output Format (optional) - GTiff for GeoTiff, AAIGrid for Arc ASCII Grid, HFA for Erdas Imagine (.IMG). Defaults to GTiff if parameter is not provided

Constraints: {'enum': ['GTiff', 'AAIGrid', 'HFA']}

south (number, query, required)

WGS 84 bounding box south coordinates

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

west (number, query, required)

WGS 84 bounding box west coordinates

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