Aerial Surveying, based in Hawaii, has investigated methods to measure distances through thick foliage for surveying and marking property lines. Traditional methods such as LiDAR and microwave radar do not work well without a clear line-of-sight view of the target, according to the company’s announcement. “It is known that when radio frequencies are at or below the UHF band, the [electromagnetic] waves can penetrate through vegetation. We designed a system to take advantage of that fact and created a working proof of concept,” Aerial Surveying noted. “We are entering the third phase of the project, producing a prototype for FCC certification.”
Presently, foliage is cleared by bulldozers, chains saws and machetes so that conventional surveying methods can be used. This is both costly and detrimental to the environment, the company said. Our patented method uses radio waves to penetrate foliage. A range detector and a two transponders are placed at the points to be measured. Damage, cost, and the need for restoration is minimized. The company has named the system Line-Pro. (U.S. Patent #10101435)
Operation
Aerial Surveying describes the process:
- The surveyor sets up a transponder tripod at two known points on the property line such as the staked property corners.
- The surveyor walks the range detector pole toward the property line. The range detector alerts the surveyor as he gets close and then is at the property line.
- These steps are repeated to create additional accurate survey points in areas when line-of-sight surveying is not possible. The process can also be used in open areas to cut down on time and know-how of setting up and utilizing costly GPS or traditional instruments.
