    2. Frame Index File (FIF) Background

    3. Example of Photo Center Point Positioning Errors

    4. Accuracy Assessment of Georeferenced Photo Index Map Sheet

    5. Georeference Lower Resolution Preview Image Using ERDAS IMAGINE AutoSync Preview images from exiting CDMP project (Conversion of Historic Aerial Photography to Metric Quality Images – L-48) Preview images georeferenced using USDA NAIP Imagery

    6. Frame Index File Attributes FrameId: Sequential number of the image Acquisition: Acquisition Project name (MD0801) ProjectId: Compilation Project name (MD0801B) FlightLine: The flight line identifier within the project (30-001) RollNumber: Internal indexing system; written on Photographic Flight Report (0523CN01) SpotNumber: Internal indexing system; written on Photographic Flight Report (200-898) State: State in which the image is located (based on the center of the image) CountyFips: County FIPS code for the center of the image ExposeDate: Date image was acquired ExposeTime: Time (Greenwich Mean Time) image was acquired ImageId: Name of image file without file extension Longitude: Longitude of the center of the image Latitude: Latitude of the center of the image Height: Altitude at time of exposure Azimuth: Heading at the time the image was acquired (degrees clockwise from north) Scale: Image scale, in thousands (Example: 67.2 means 1: 67200) SensorType: Sensor (camera) type code Emulsion: Film emulsion type code (Color, Panchromatic, Infrared) And Many More…

    7. Sources for FIF Validation Photographs Photo Index Map Sheets Photographic Flight Reports

    8. Update National Geodetic Survey’s Frame Index File Outcomes Improve geospatial and metadata accuracy of the Frame Index File Resolve differences between photographs/Frame Index File/Photographic Flight Cards/Photo Index Map Sheets Identify and include excluded photographs in Frame Index File Provide geospatial preview images and FGDC metadata
