NCRST-E Briefing: Corridor Planning and Environmental Assessment
Joint Program Oversight Committee Meeting
October 25, 2002
MS Gulf Coast
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 investigating land cover and land use change and impacts of change and developmentat various scales and inmultiple settings.The research is providingimproved understandingabout environmental andhydrologic impacts of transportation development.
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.
Hyperspectral image data were collected andclassified to obtain classes that closely resembled those used in
NWI surveys. LIDAR was used for terrain and hydrologic analysis.
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.
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 ….View Data in a Map….. Select Areas of Interest.... Refine the Area of Interest....
AND …. Create Consistent CUSTOM Geospatial Image Products that meet the needs of transportation agencies!
The CME is a technology that hides the complexity of data storage, management, and processing from the user and provides a web-based method of access to computational resources that replace traditional image processing workflows …..
Web Access to Data and Methods…. AND Computational Workflows!
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.

Regional Database Development for
Proposed Remote Sensing/GIS Solution Paradigm
1. Change detection analysis for updating landcover/
2. Sharing of data across the Internet via an Internet Map
3. GIS based planning tool for automatic calculation of
environmental impacts, creation of impact matrices and
development of alignment mapping.
PROJECT TITLE: Automating Wetlands Identification to meet Federal Reporting Requirements
Objective: Integration with existing GIS architecture to streamline the process for planned road construction projects
Remote Sensing and the Planning Process
Remotely sensed wetlands data can be introduced early in the planning process
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.
