Description:

Abstract:

AirPhotoUSA imagery is true color, high resolution, seamless digital ortho-rectified aerial photography.

Purpose:

The purpose of this data set is to provide visual information through current and accurate Aerial Photography, supplemented with geographical data. These Aerial Datasets have been produced as a result for the need to have geospatial data immediately available and accessible for a wide variety of end-users.

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The final product precision is computed by AirPhotoUSA's exclusive orthorectification software as a measure of the error between the planimetric reference and the final orthorectified product. When the images are orthorectified all of the image pixels are adjusted according to the computed orthorectification solution where the distortion from the camera and surface topography is removed. Thus any vertical error that may exist in the DEM is dealt with in the orthorectification solution. As each image is orthorectified the pixels at the original aerial triangulation measurements in each image are compared between the orthorectified imagery and the planimetric reference in the orthorectification solution. A root mean squared residual is computed for each measurement and combined to provide an RMSE for each image. These image RMSE's have been statistically combined to provide one single RMSE for a project. Since the distortion due to the surface is removed during orthorectificat! ion there is no vertical data in the final orthorectified product.

Quantitative_Horizontal_Positional_Accuracy_Assessment:

Horizontal_Positional_Accuracy_Value: 7.45

Horizontal_Positional_Accuracy_Explanation:

This product reported an averageof 7.45 feet horizontal precision to reference at 95% confidence level.

Process_Step:

Process_Description:

Each image within the Aerial Mosaic was scanned in as film at a resolution of 1300 dots per inch (dpi). An Aerial Triangulation solution is derived using proprietary AirPhotoUSA software and external reference sources. This Aerial Triangulation solution is tested using available photo identifiable ground control data acquired by a licensed surveyor. Horizontal control for the Aerial Triangulation solution was provided using a combination of ground survey points and orthoimages with known x-y uncertainty. Once the solution is within the required accuracy standards, the images are orthorectified using proprietary AirPhotoUSA software. Vertical control for the orthorectification process is obtained from a Digital Elevation Model (DEM). These DEMs are usually acquired from the USGS or from a custom source. Each orthoimage is then tiled to a common extent and then mosaiced using proprietary AirPhotoUSA in NAD83 datum and State Plane projection. Color balancing and dodging was per! formed using proprietary software. Every orthoimage are visually inspected for any anomalies incurred in the production process i.e. misalignments along mosaic seamlines, scanner artifacts and voids in the DEM.
