Description:

Abstract:

This project consists of photogrammetrically produced planimetric mapping, DEM creation, and digital color orthophotography of the State of West Virginia. The W.V. state plane system has two cartographic zones, north and south. This data set consists of 10,000' x 10,000' MicroStation DGN files of the north zone DEM data. The aerial photography used for this project was captured at a negative scale of 1" = 2400' in the spring of 2003.

Purpose: Aerial survey of the state of West Virginia

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The accuracy of the ground control and airborne GPS data is confirmed by the evaluation of the results of the analytical bundle adjustment. The residuals of the final adjustment ensured compliance with NSSDA standards. During the scanning of the original aerial film, the image histogram for each frame is carefully examined to ensure that the image has been scanned so that the minimum and maximum brightness values are captured to eliminate any loss of detail due to saturation of dark or light areas. Evaluation of the DEM includes checking the terrain data for spikes and wells, omissions, and other anomalies that do not meet the project accuracy requirements. Using the adjusted horizontal coordinates of the aerotriangulation points, their heights are interpolated from the neighboring DEM points. The interpolated coordinate of the aerotriangulation point is then compared with the actual adjusted Z value of the aerotriangulation result. Visual inspection of the stereoscopic model and contour lines (generated only for QA/QC purposes) is also made allowing the detection of errors in the DEM.

Logical_Consistency_Report:

All files are inspected by the Production Manager to ensure that they conform to the specified file naming conventions, all files load in their correct geographic position, all files conform to the project specifications for file standard and content.

Completeness_Report:

All files are visually inspected for completeness to ensure that no gaps or misplacement exists in the data. The files have been checked to ensure that the boundary and the content has been covered in its entirety.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The planimetric data has a <9.79 ft. horizontal accuracy at 95% confidence level, National Standard for Spatial Data Accuracy (NSSDA), for a 2.0 foot Ground Resolution Distance (GRD). Horizontal accuracy determined as 1.7308 times the RMSE circular error(1.4142 x 4' = 5.657'). This requirement will not be applicable in areas where the ground is obscured on the aerial photography by foliage, prevalent smoke, or dense shadow.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

All DEM data will meet a vertical accuracy of +/- ten (10) feet at the 95% confidence level consistant with NSSDA standards. This requirement will not be applicable in areas where the ground is obscured on the aerial photography by foliage, prevalent smoke, or dense shadow.

Aerial photogaphy was supplemented with the simultaneous acquisition of airborne GPS data, which captured the ground coordinate for the nadir point of each photograph. Aerial photography was exposed at an altitude of 14400' above mean terrain yielding an approximate scale of 1:28800.

Process_Description:

Softcopy aerotriangulation utilizes the GPS ground control and image coordinate measurements which are run through bundle block adjustment software computing the exterior orientation parameters for each image of the photogrammetric project. The original aerial film was scanned utilizing a Socet Set DSW600 precision photogrammetric scanner at a resolution of 12.5 microns. Using these scans the aerotriangulation process employs a rigorous mathematical model which detects measurement errors, and corrects for systematic image distortion, film shrikage, atmospheric refraction and camera lens distortions. The final bundle adjustment results are inspected to ensure that the RMSE meets the required 1 part in 10000.

Process_Step:

Process_Description:

The procedure utilized for the development of the DTM/DEM development used a combination of automated and manual techniques. The initial phase produced an intermediate terrain data set using a series of automatic data processing algorithms known as Automatic Terrain Extraction. This data set is further refined using a series of automatic filtering techniques, along with visual inspection and editing processes to produce a fully compliant DEM meeting the project specifications. To enhance the results of the ATE process linear and polygonal break line information was collected in all areas where a more rigorous data set was required to define changing terrain conditions. This break line data is then merged into the correlated terrain file and used to influence the DTM by correcting areas where the ATE process has failed to depict the terrain accurately.
