The National Science Foundation (NSF) Institute for Geospatial Understanding through an Integrative Discovery Environment (I-GUIDE, https://iguide.illinois.edu/) aims to transform geospatial data-intensive sciences through the integration of AI and cyberGIS, reproducible data-intensive analytics and modeling, FAIR (Findable, Accessible, Interoperable, and Reusable) data principles, and innovative education and workforce development programs. I-GUIDE is conducting a virtual consulting office (VCO, https://iguide.illinois.edu/i-guide-vco/) to showcase innovative research and education advanced by I-GUIDE. The VCO is designed to address the ongoing needs of pertinent communities and partners.











GeoEDF: A Framework for Designing and Executing Geospatial Research Workflows




Geospatial researchers often spend much time wrangling data in their workflows. These data wrangling processes are typically ad-hoc, involving a mix of desktop, interactive computing, and HPC tools, requiring data to be transferred from one platform to another. Notwithstanding the time spent away from doing research, these processes become hard to maintain amidst research group turnovers, ultimately affecting research reproducibility. GeoEDF is designed to address these challenges by enabling researchers to conceive their workflows as an abstract sequence of data acquisition and processing operations. Reusable workflow building blocks (namely, data connectors and data processors) implement suitably generalized data acquisition and processing operations that can be composed into concrete workflows. The GeoEDF workflow engine plans and executes these workflows in HPC environments, abstracting away the complexities of intermediate data transfer, HPC job scheduling, and parallelization.

In this virtual consulting office session, we will provide an overview of the GeoEDF project and its implementation, GeoEDF workflow syntax and semantics, and the cyberinfrastructure platforms that can currently be used to develop and execute GeoEDF workflows. We will demonstrate data connectors and processors through examples from I-GUIDE convergence science use cases and discuss GeoEDF integration pathways with other cyberinfrastructure platforms.
