MS Gulf Coast Research Activities
NCRST-E is conducting an assessment of land cover and land use change in the Mississippi coastal corridor with the purpose of identifying changes due to transportation and land development. New techniques for classification and analysis were developed.

NCRST-E is Studying Transportation Impacts on Air Quality by Using LIDAR Technology
The NCRST-E air quality project is focused on the adverse effects of air pollutants. The primary objectives of this project are: (1) developing guidelines on the use of remote sensing Differential Absorption LIDAR (DIAL) for real-time measurement of air pollution resulting from highway traffic and (2) an air quality model for prediction of air pollution considering the impact of highway traffic, land use, terrain type, and climatic factors.

NCRST-E is Developing New Geospatial Applications and Processing Algorithms for Wetlands Assessment
Soils
Hydrology
Vegetation
The assessment of vegetation, soils, and hydrology forms the basis of standard wetlands field assessments.Determining how those assessmentsare made facilitates the development of surrogate processes using RS and geospatial technologies to producesimilar results.

Hyperspectral Image and LIDAR Data forWetland Identification, Mapping, and Analysis Randolph County, North Carolina
Hyperspectral image data were collected andclassified to obtain classes that closely resembled those used inNWI surveys. LIDAR was used for terrain and hydrologic analysis.

Hyperspectral Image and LIDAR Data for Wetland Mapping and AssessmentEddyville, Iowa
For a new bypass project, the Iowa DOT determined that there were landscape features that gave rise to wetlands in an area where they have planned an alignment. With involvement of NCRST-E high spatial resolution hyperspectral image data will be used to identify areas where wetland vegetation occurs.

Quantitatively assessing the likelihood of wetlands occurrence requires that vegetation classes be stratified and clarified then ranked, combined, and assessed in the context of hydrology and soils for the area. To accomplish the contextual analysis, data analysis steps and products are grouped into vegetation and non-vegetation information groups. Soils and hydrology information products combined to contribute 30 possible points and the vegetation information products combined to contribute 30 possible points.

Computational Resources for Geospatial Data and Information Use, Distribution, and Management
In a peer review meeting of the TRB statewide GIS committee a consistently echoed theme was the need for improved access and distribution of standard, consistent data sets that are useful for transportation planning and assessment as well as early phases of design.
NCRST-E is working to develop technology for Computational Mapping Engines and Distributed Geospatial Data Libraried that will allow agencies to ….

NCRST-E Research Formulation:Corridor Planning and Environmental Assessment
NCRST-E held a workshop (GICAP 2002) to address the challenge of using remote sensing and geospatial technologies for corridor planning and assessment activities.
Topics and presentations ranged geographically and by transportation modes including such diverse areas as the Alaska Natural Gas Pipeline, the Virginia Base Mapping Project, and the Mississippi Gulf Coast CSX Railroad relocation project.

Remote Sensing and the Planning Process
Remotely sensed wetlands data can be introduced early in the planning process
Benefits include:– Incorporation with other available GIS data layers – Good preliminary indication of potential impact – Provides an accurate guide to field
reconnaissance and survey

The project goal will demonstrate the use of commercial software and remotely sensed data to produce information products that streamline the environmental analysis process for transportation project planning. This project is developing land use land cover data using remote sensing technologies in concert with other digital geospatial resources and methods for the same I-405 corridor, then applying that information to appropriate environmental impact statement topics to determine benefits as compared to traditional environmental assessment methods already performed.
