Complete Data Set
This data set was tested to meet ASPRS Positional Accuracy Standards for Digital Geospatial Data (2014) for a 0.5-foot RMSEx / RMSEy Horizontal Accuracy Class. Actual positional accuracy was found to be RMSEx = 0.058-foot and RMSEy = 0.093-foot which equates to Positional Horizontal Accuracy = +/- 0.184-foot at 95% confidence level.

The image data was acquired by Keystone Aerial Surveys.
The image data was acquired using a Leica DMC III image sensor installed in a fixed-wing aircraft. The imagery was controlled using a combination of airborne GPS and IMU data collected during the flight and surveyed ground control points. Accuracy was validated using surveyed check points used only for the assessment of the accuracy of the data. Details of the flight and survey can be found with the project deliverables (Control Survey Report and Flight/ABGPS Report).

The imagery was triangulated using Cardinal System's VR AirTrig software. The EOs were processed and verified in stereo. Final adjustments were verified and checked against the surveyed aerial targets and were within minimum accuracy requirements for this project (see AT Report files included with project delivery).
