wcs 0.1.0

Python client library for WCS (OGC Web Coverage Service) backends.

Overview

The OGC Web Coverage Service (WCS) standard defines support for modeling and retrieval of geospatial data as coverages (e.g. sensor, image, or statistics data).

This Python library allows to extract information about WCS coverages from a given WCS endpoint.

Installation

pip install wcs

Examples

from wcs.service import WebCoverageService

wcs_endpoint = "https://ows.rasdaman.org/rasdaman/ows"
service = WebCoverageService(wcs_endpoint)

# get a list of all coverages, with basic information such
# as a WGS 84 bounding box and a native bounding box
coverages = service.list_coverages()
avg_land_temp = coverages['AvgLandTemp']

# get full information for a particular coverage by
# parsing its DescribeCoverage document from the WCS server
full_avg_land_temp = service.list_full_info('AvgLandTemp')
