Census-independent population mapping in northern Nigeria

Although remote sensing has long been used to aid in the estimation of population, it has usually been in the context of spatial disaggregation of national census data, with the census counts serving...

Uncertainty in Estimates of Bioenergy‐Induced Land Use Change: The Impact of Inconsistent Land Cover Data Sets and Land Class Definitions

While many data sets are increasingly available to describe land cover characteristics, these data require careful analysis and supplemental research before conclusions can be drawn about the scope,...

Constraint-Based Routing Models for the Transport of Radioactive Materials

The Department of Energy (DOE) has a historic programmatic interest in the safe and secure routing, tracking, and transportation risk analysis of radiological materials in the United States. In order...

Research

The Geographic Information Science and Technology (GIST) Group at the Oak Ridge National Laboratory has been a pioneer in the development, implementation, and application of systems, science, and technology for geographic information since 1969 - well before the advent of commercial GIS.  In the DOE national laboratory system, it is the only computational research group focused on advancing the theory and applications of geospatial science and technology.   Today, the GIST group is an internationally renowned R&D organization of over thirty diverse scientific professionals who bring together a wide range of expertise ranging from GIS and remote sensing technologies to key domain sciences.  We focus on developing innovative, knowledge discovery, solutions to solve multidisciplinary and complex problems for energy, environment, and national and homeland security missions.  In addition, we actively partner with leading academic institutions to collaborate with faculty members and engage students to support the national priority of research, education, and workforce development.

Current research and development activities span across high resolution population distribution and dynamics, energy assurance including modeling and visualization of the electric grid and biomass and bioenergy resources, climate change science including climate extremes and integrated impact analysis, emergency and disaster management, critical infrastructure modeling and simulation, and earth science informatics.  Our work has been supported by the U. S. Departments of Energy; Department of Homeland Security; Department of Defense; Department of Transportation; Environmental Protection Agency; Bureau of Census; National Aeronautics and Space Administration; National Institute of Health; National Oceanic and Atmospheric Administration; and a number of member agencies of the Intelligence Community.
