Build Status

pyGDP provides a fast and efficient way of making calls to the USGS GeoData Portal.

pyGDP has the following algorithms: - FeatureCategoricalGridCoverage - FeatureWeightedGridStatistics - FeatureCoverageOPenDap - FeatureCoverageWCSIntersection

Before using the Geo Data Portal via Python, please read the scalability guidelines.

Additional documentation can be found at the Geo Data Portal wiki.


pyGDP request owslib and lxml.etree (which, in turn, uses libxml2 and libxslt)


You can find example usages and scripts in the examples folder.


1.) Use of virtualenv and pip is highly recommended. Sample commands to install pyGDP as a virtual env on a mac/unix operating system are given below. Similar commands can be used on windows.

git clone
virtualenv -p /usr/bin/python2.7 pyGDP/venv
source pyGDP/venv/bin/activate
pip install -r pyGDP/requirements.txt
pip install -r pyGDP/testing-requirements.txt
cd pyGDP
python install
lettuce Lettuce_Tests/features/ --tag=-not_working

Anaconda and other package managers can be used, but pyGDP must be installed from source.

For pip, do: pip install owslib==0.13.0

For Anaconda, do: conda install -c conda-forge owslib=0.13.0

Then download the latest release of pyGDP here:, extract its contents, and run:
python install
with the python environment you installed owslib into active.
