Amazing AccuracyThe desired accuracy level or better has been achieved for clients on every project completed using the eagleeye mapping system. The system’s accuracy is derived from the integrated GPS and IMU as well as the Tuck process of establishing “control” at the beginning of each flight mission and maintaining excellent control throughout. In addition, our data processing techniques enhance the accuracy of the processed data even further. Tuck’s experience and expertise with ground surveys and photogrammetric mapping enable us to fenhance the quality of the data during processing.
Accuracy for the eagleeye system is a function of altitude. At typical flight altitudes of 300’-800’ AGL, vertical accuracy of approximately .1’ is obtained on hard surfaces and open terrain. Vertical accuracy is slightly less for other situations involving hilly terrain and vegetated surfaces. However, accuracy of between 2”- 8” is normally obtained in these situations.
Some of the projects recently completed with the eagleeye system and the level of accuracy achieved include:

Nuclear Power Plant 1.3"
I-81 Interchange 0.5"
Barnes Air National Guard Base 1.4"
I-66 near Dullas 0.5"
