Purpose: This imagery was flown and processed by Aerial Imagery Services, LLP in support of Tamarix (Salt Cedar) eradication along the Canadian River. It was flown during a temporal window of decidous senescence when Tamarix is typically more distinct from associated species.

Each digital sensor was individually tuned to capture the dynamic range of reflectance values in the respective band. Orthorectified images were created by the mosaic of multiple digital image frames. Radiometric values within the mosaic were rendered by statisical methods using multiple digital image frames. Additional note: This mosaic received linear contrast stretching, including saturation, to enhance visual interpretation and was compressed using ER Mapper ECW compression (target compression ratio 20:1). This may result in the loss of some image detail. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: This orthoimage was produced using a combination of aero-triangulation and ground control points obtained from existing Texas Orthoimagery Program (TOP) digital orthophoto quarter-quadrangles (DOQ). This process attempts to replicate the spatial characteristics of this widely used base mapping. TOP DOQs meet the National Map Accuracy Standards (NMAS) for 1:12,000 scale products.

Origin information was captured by Differential Global Positioning System (DGPS) and inertial Attitude Heading Reference System (AHRS) sensors. Stereo pair image frames, related by tie-points and ground control points, were identified within image frames and geo-location was performed with bundle-block methodology. A digital elevation model (DEM), for generation of mosaic imagery, was created from bundle-block calculations. Radiometric values within mosaics were rendered by statistical methods using multiple digital image frames. In some cases, spectral quality has been enhanced by solar correction algorithms or histogram adjustment. Spatial quality assessment was performed by calculation of residual errors of sampled points between this image and corresponding Texas Orthoimagery Program (TOP) Digital Orthophoto Quarter-quadrangles (DOQ). Additional note: This mosaic received linear stretching, including saturation, to enhance visual interpretation and was compressed using ER Mapper ECW compression (target compression ratio 20:1). This may result in the loss of some image detail. Process_Date: October 2004 - April 2005 Process_Step: Process_Description: Metadata imported.
