GIS Research--Image Acquisition and Processing

The Geographic Information System (GIS) is an Arc/INFO coverage comprised of arcs, nodes, and a route system that geographically represents the roadways maintained in the Roadway Characteristics Inventory (RCI). Because of Florida's continued rapid growth, up-to-date imagery is constantly needed to help maintain the road system and plan for the future. The purpose of this project is to research the existence, acquisition and processing of imagery that is more recent than the 1999 Digital Ortho(-photography) Quarter-Quads (DOQQs). As a result of this project the Florida Department of Transportation (FDOT) has been able to acquire high resolution imagery for over 40 Florida counties. An inventory of the more up-to-date imagery was created, the imagery acquired and finally reformatted for use in the FDOT's Transportation Statistics Office and throughout other offices as well. The FDOT can now more effectively manage the basemap, which is used for several purposes, including: providing a quality assurance tool for RCI feature lengths; dynamic segmentation - the creation of GIS data layers from RCI features; map production; creation of the State's city-to-city mileage matrix; and modeling.
