NCRST – Environment (NCRST-E) focuses research on the goal of providing cost effective corridor assessment and planning tools. The NCRST-E research partners apply remote sensing imagery of increased spatial, radiometric, and temporal resolution to the analysis of transportation impacts on the environment, both natural and man-made.
Transportation, Development, and Transportation, Development, and Land Cover Change Land Cover Change For the Mississippi Gulf Coast I-10 and Coastal Corridor and for an area in the Appalachian Region, the NCRST-E’s land cover classification and change detections efforts are producing significant results and will assist current corridor planning efforts in Mississippi for the CSX railroad and I-10.
Technology outreach between researchers, “on-the-ground” practitioners, and regulators is critical to the development of enhanced approaches for wetland identification. Cost-effective, acceptable approaches for the use of remotely sensed data in wetlands identification, mapping, and mitigation planning will provide improved screening and selection of transportation alignments.

Needs, Air Quality, and Needs, Air Quality, and GeoLibrariesGeoLibrariesNCRST-E’s research, technology application, and education programs respond to the evaluated environmental assessment geospatial information needs of transportation stakeholders. Needs assessment studies, evaluations of air quality related to transportation, and all other investigation point to the need for improved data resources for transportation assessment. Digital GeoSpatial Data Libraries (GeoLibraries) are a high priority area of research and development for NCRST-E
Technology Application ProjectsTechnology Application ProjectsNCRST-E efforts are linked to technology application projects (TAPs) that demonstrate how information products derived from remote sensing and related technology can be used by transportation professionals.

Protecting the nation’s transportation infrastructure against terrorist attacks has become a top priority, and will be an evolving industry as advanced technology enables more sophisticated, real-time,
continuous monitoring.
Protecting the Aviation Infrastructure
LiDAR, high-resolution satellite, and airborne imagery provide current spatial information on airport facilities and help to identify obstructions in the surroundingairspace. These technologies enhance airfield protection, security, and safety by allowing airport managers to visualize a broad range of spatial information in three dimensions.
Safety has always been an important issue for pipeline operators. Pipelines are one of the vulnerable critical infrastructures that can be monitored and protected using chemical detectors and remote sensing technology.

A mounted video camera is used to test a procedure to automatically detect & match vehicles.
Effective real-time/near-real-time traffic management depends on the accuracy of current traffic flow information. Remote sensing can aid in the detection & estimation of queue formation, platoon progression & turning fractions.
Distance & speed are calculated from helicopters using video cameras. Use of spectral signatures to automatically track vehicles makes the calculations possible.
LIDAR data is proving to be a useful addition to our sensor capabilities producing minute variations in surface elevations.
