Study shows “negligible differences” in UAV survey accuracy

Via Sensfly. An Arkansas farm operator sought to test Sensefly UAV survey accuracy to see if data were usable for planning and levee design compared to ground-based RTK surveys. The ground RTK surveys are typically performed by having the RTK unit mounted on a vehicle and driving the site. The terrestrial RTK method is often [...]

RTK UAV (drone) topographic survey at Sunset Bay – Sharps Chapel TN

This orthophoto is very useful for design purposes by showing the adjacent structures, particularly the existing docks, which tend to cramp the client's lake access. What architect wouldn't love to have all this information? In addition, it is helpful to know the existing conditions for liability purposes. The photo is absolute proof of the pre-construction [...]

3D Airspace Map Inside Google Earth! Plus… FAA Sectional geoTIFFs FREE

My recent discovery of 3D airspace maps from 3Dairspace.org is one of the coolest things I have seen in awhile. Small UAV operators may find airspace confusing and FAA sectionals difficult to interpret. While the 3D airspace map inside Google Earth is no substitute for reading current sectional charts, it does serve as a great [...]

The Big GPS Fix

As a land surveyor, one wonders how RTK GPS market prices are sustained at such high levels. A look at the world market reveals wide-spread availability of relatively cheap RTK GPS surveying equipment everywhere except here in the U.S. The market here is dominated by a few big players like Leica, Trimble, and Topcon, while [...]

No Stone Unturned: How NecroSearch International uses Drones and UAV’s to find hidden graves

While reading the fascinating book No Stone Unturned: The True Story of the World's Premier Forensic Investigators, I ran across this short passage describing how the organization began to use UAV's to help locate clandestine graves.

No property is safe. Watch a roomful of government officials collude to take innocents’ property.

Every citizen should educate themselves concerning the threat of civil asset forfeiture. There is no presumption of innocence in such cases, and government is incentivized to take as much as possible. The blatant collusion taking place at this New Mexico meeting has to be seen to be believed. Civil Forfeiture is a “Gold Mine:” “We [...]
