| Lineage | Scanner: Intergraph PhotoScan TD Photo Digitizing System. Scanner Geometric Calibration: Standard Deviation (sigma) = 1.6710356970 Root Mean Square X = 1.9970393211 Root Mean Square Y = 0.9624905604 Scanner setting: Transmissivity: 0.0151 0.6610 Film Density: 1.8210 0.1778 Gamma: 1.75 Quality Control Procedures: Film was kept in airtight containers prior to scanning. Both the base and emulsion sides of the film were cleaned using a tacky roller system prior to scanning. Color adjustment was achieved by visually matching the tone, contrast, and brightness to the original film. Each scanned image was checked computationally for missing data. Quality Control Procedures for orthophoto production: After individual orthophotos were mosaiced into a regional database, the resulting orthophoto composite was visually inspected for tone balance and image distortion. In areas of image distortion, more suitable orthophoto imagery was inserted, when possible. The final orthophotos were visually inspected for accuracy and consistency. |
