Resolutions Available and Typical Flight Times
*Flight times vary based on large terrain elevation changes, obstacles, and prevailing wind speeds
High Resolution: 2 - 3 cm/pixel GSD - Collected at 140ft. Above Ground Level (AGL)
Flight time* needed to map per 100 Acres: 70 Minutes
Medium Resolution: 3.5 - 4.5 cm/pixel GSD - Collected at 280ft. AGL
Flight time* needed to map per 100 Acres: 35 Minutes
Low Resolution: 5 - 7 cm/pixel GSD - Collected at 400ft. AGL
Flight time* needed to map per 100 Acres: 25 Minutes
UAS collected aerial imagery. Resolution is given in terms of how many centimeters each pixel in the photo represents (cm/px). This is the Ground Sampling Distance (GSD). The lower the number the higher the resolution.
Global accuracy of orthographic imagery provided is dependent upon the number and accuracy of Ground Control Points (GCPs). We ask clients to provide at least 5 GCPs in the area to be mapped however we can arrange to have GCPs recorded.
In absence of GCPs, our global accuracy is typically 1-3 meters x,y and 5-7 meters z using our Unmanned Aircraft's onboard GPS.
