Center of Excellence for Geospatial Information Science (CEGIS)

CEGIS research is focused on The National Map and 3DEP

The CEGIS vision is to conduct, lead, and influence the research and innovative solutions required by the National Spatial Data Infrastructure (NSDI) and the emerging GeoSpatial and GeoSemantic Web. CEGIS is a virtual organization with Federal and academic affiliate scientists conducting research in support of The National Map and the Three-Dimensional Elevation Program (3DEP).


Current CEGIS Projects

Data IntegrationData Integration - Thomas Shoberg
Data Integration research at CEGIS primarily involves integrating data from The National Map with selected datasets needed to support visualization, analysis, modeling and decision making efforts of the USGS, other government agencies and the general public.

GeoWebGeospatial Semantics and Ontology - Dalia Varanka
Semantics of geospatial data and information to build user interfaces to USGS archives of science and data.

HPCHigh-performance Computing (HPC) - Michael P. Finn
Perform investigations into understanding HPC applications development challenges in the scientific domain, particularly in GIScience, focusing on problems and issues related to multi-resolution raster data; using the pRasterBlaster software package as a case study.

Multiscale RepresentationMultiscale Representation - Larry Stanislawski
This project identifies relations between map scale and geomorphological characteristics of cartographic features to automate generalization and define ontology patterns for feature extraction.

Data ModelingSpatiotemporal Data Modeling - E. Lynn Usery
Multidimensional data models for support of The National Map, the 3 Dimensional Elevation Program (3DEP), and geospatial semantics.

VGIVolunteered Geographic Information, Social Media and Citizen Science - Barbara Poore
Integrating volunteered geographic information (VGI), social media, and citizen science with USGS science and data programs.
