Abstract:This project was directed toward research in the development of spatial information systems for transportation. The project and all software development was done in the Intergraph MGE environment. One objective was to investigate software tools for locating spatial data. A system called the Archival Management System (AMS was developed to assist in the management of a spatial data archive. The AMS can manage data describing aerial photographs, satellite images, maps or Intergraph design files. Pavement Management and Storm Discharge Prediction demonstrations were conducted to study methods of spatial data translation and database integration as well as applications of these databases to pavement management and storm discharge prediction. Highway needs data and pavement history and quality data were utilized to develop a prototype Pavement Management System. The storm discharge prediction demonstration was designed to study methods for utilizing spatial databases with modeling programs for predictive purposes. Since the cost of acquiring spatial data is high, another objective was to investigate sources of spatial data. Data collected from Global Positioning Systems (GPS) as well as remotely sensed data obtained from satellites and aircraft were studied. These data were examined for their utility in maintaining the cartographic and highway inventory database. We photointerpreted, digitized, and analyzed road networks from SPOT Satellite digital data and transparencies as well as the National High Altitude Photography (NHAP) and National Aerial Photography Program (NAPP) aerial photographs. Video and high resolution aerial photography were interpreted and evaluated for their suitability in providing inventory data.
