Description

PAMAP Program Cycle 1/DVRPC 2005 Digital Orthoimagery High Resolution Orthoimage (2003 – 2006) – cached mapservice. This mapservice has been created by Penn State Institutes of Energy and the Environment (PSIEE) as a high performance background image for applications.

An orthoimage is remotely sensed image data in which displacement of features in the image caused by terrain relief and sensor orientation have been mathematically removed. Orthoimagery combines the image characteristics of a photograph with the geometric qualities of a map. For this dataset, the natural color orthoimages were produced at 2-feet pixel resolution. The design accuracy is estimated not to exceed 4.8 feet at the 95% confidence level. Each orthoimage provides imagery for a 10,000 by 10,000 feet block on the ground. The projected coordinate system is Pennsylvania State Plane with a NAD83 datum.

Horizontal Positional Accuracy

The horizontal accuracy of the orthorectified images is mainly determined by the accuracy of the aerotriangulation and digital elevation model (DEM). The DEM accuracy assessment was achieved by comparing the aerotriangulation-derived elevation with the elevation of the DEM at the same X and Y coordinates. In addition, visual examination was employed to assess all tiles and its relative edge match. All results were examined for consistency and its compliance with the NSSDA accuracy standard.
