    Digital 3D Stereo Imagery Datasets

    Derived from standard aerial stereo pairsEvery pixel in the image is accurately georegisteredBased on algorithms designed for smart bomb targetingTypical accuracies in x,y, and z

    1200 ft. imagery +/- 3cm x,y, and z2000 ft. imagery +/- 8cm x,y, and z

    Roadway Characteristics/Asset Data Collection

    Datasets created for approximately 2000 miles of FDOT District 3 Currently in daily use by FDOT to extract

    and view roadway characteristics dataUses have expanded to include design,

    maintenance, and traffic operations

    Survey Data Extraction

    Pilot project in FDOT District 3 Demonstrated capability of extracting

    survey points accurate to +/- 3cm x,y,zProviding approximately 90% of data

    points required for roadway designProvides standard output formats

    compatible with CAiCE and Geopak

    2D/3D Shapefile Extraction and Digital Elevation Data Extraction

    Used in Okaloosa County Florida for NPDES Phase II Stormwater data collection and floodplain analysisData extracted in standard shapefile formatsElevation data derived using edge detection

    algorithms developed for DODProvides for vector data visualization in stereo

    Overlay allows for visual data QA/QCAlso used for FAA Part 77 obstruction

    clearance assessment
