GPS/GIS Inspection and Analysis Tools for Highway Construction Integrated GPS/GIS Application for Inspection and Analysis FDOT’s Microstation drawings converted into Geographical Information System (GIS) Basemaps, with correction to the proper projections; Specifications; and Pay Items' Original Quantities. Global Positioning System (GPS) Receivers Capture Pay Item Locations and Pertinent Dimensions for Quantities. Database to Store Inspection Results: Observed Quality of Construction, Lab. Test Results, etc. and Digital Images GIS Analyses and Database Queries Provide Monthly Display of Construction Progress and Estimate of Quantities, including As-Built Final Drawings and Quantities.
