ABSTRACT
The OpenTopography science gateway provides efficient online access to high resolution topographic data and processing tools for a broad spectrum of research communities. We have integrated XSEDE HPC resources into the OpenTopography processing workflow to meet the growing demand for more complex and resource intensive algorithms from the wider community.
