Image-to-Intelligence Archive (I2IA)Assisting Image Analysts in Building and Using Archives
The amount of data available to an image analysts today is enormous
We are developing an agent-based system architecture that autonomously
manages a massive but dynamic image data archive
transforms that to an intelligence or information archive to aid national security needs

Transportation Routing Analysis GISWeb-TRAGIS
Transportation Routing Analysis GIS (TRAGIS) model is used to examine highway, rail, and waterway routes for route campaigns or future shipments
Transportation routing model used by DOE community for routing and risk assessment studies
OAK RIDGE NATIONAL LABORATORYU. S. DEPARTMENT OF ENERGY
TRAGIS Rail Network
1:100K rail network development sponsored by Dahlgren NSWC Joint Program Office
Uniquely value added and topologically refined
Used for infrastructure assurance analysis
Also incorporated into Transportation Routing Analysis GIS model, funded by DOE/NTP
OAK RIDGE NATIONAL LABORATORYU. S. DEPARTMENT OF ENERGY
TRAGIS Routing Model
Transportation Routing Analysis GIS (TRAGIS) model is used to examine highway, rail, and waterway routes for route campaigns or future shipments
Output includes population data along routes for risk assessment models

LandScan Global Population
Accepted standard for estimating population at risk by the DoD and DOS
Federal agencies including DoD (DTRA, NGA), DHS (FEMA, TSA), DOE, USGS, NASA, EPA, and HHS (CDC, NIH) are current users of the data for research and development and routine exercises
Over 1200 non-defense registered users worldwide including WHO and the UN agencies
Used in Rand McNally’s World Goode’s Atlas and National Geographic Maps
Finest spatial resolution (<1km) global population distribution ever produced
Global coverage in consistent raster (GIS) format
Regular (yearly) updates
First to employ satellite imagery worldwide
Allows quick and easy assessment, estimation, and visualization of population at risk
Integrated with transportation, socioeconomic, and consequence assessment models (HPAC)
