Project Location

Transportation/Environmental Concern

Project will allow transportation planners and environmental scientists to rapidly evaluate a project area and determine alternative solutions without having to conduct multiple fieldinvestigations.

Proposed Remote Sensing/GIS Solution Paradigm

1. Change detection analysis for updating landcover/ landuse

2. Sharing of data across the Internet via an Internet Map Server (IMS)

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

Integration with existing GIS architecture to streamline the process for planned road construction projects

“As is” Planning Process

Wetland surveys are conducted using:– 1987 Corps of Engineers Wetlands Delineation

Manual

Supplemental information from:– National Wetland Inventory– 1959 Soil Survey (USDA-SCS)– Aerial photography– Field Reconnaissance

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

Integration with VDOT’s GIS Architecture

Derived wetland polygons will be made available through VDOT GIS– Thin client, web-enabled, enterprise wide

Oracle, ESRI/SDE, and ArcIMS software

– Data will be integrated with other enterprise GIS Data

Planned Investigative Approach

Route 17, City of Chesapeake Virginia

Review VDOT wetland identification processes for projects

Review completed processes for Route 17 Acquire Erdas Sub-pixel software Identify and acquire imagery Establish reflectance ranges for vegetation

types

Planned Investigative Approach

Unsupervised and supervised classification routine refinement

Output polygons to compare with existing GIS data (soil types, NWI)

Compare to existing field reconnaissance data Load polygons into enterprise GIS to make available to

Environmental Analysts Environmental Analysts “redline” data Redlines available to others via internal web GIS

Planned Investigative Approach
