History
Did you know that….
The earliest recorded use of an unmanned aerial vehicle for warfighting occurred on August 22, 1849 when the Austrians attacked the Italian city of Venice with unmanned balloons loaded with explosives?

Transit Survey – Total Station
From manual to digital transit
Source: google.com
Traditional Topographic SurveyTotal station allows the surveyor to measure heightsand positions for number of pointsSome points cannot be accessed due to unsafeAccess, especially in landfill environmentAccuracy of about 0.05” (1.5mm)It depends on the experience of the surveyors
Traditional Survey
For example: approx. 500 acres (200 Ha)Total number of points: 1,275Distance between points: 80 ft (25m)Estimated area of “polygons”: 6,400sf (625m2)
Drone TechnologyUse similar technology as aerial topo surveyFAA regulated for commercial usePermit Application may take up to one year
to approveRequired pilot license and certificate to
operateSCS has the permit with 5 licensed pilots
and 2 quadcopter drones (DJI Phantom 3)
Drone TechnologySeveral models available in the market are equipped with: photometric HR sensors, GPS, automatic navigation systems, etc.
Using a drone can vastly reduce the time spent in collecting accurate data A direct interface software permits easily translate the information to 3D
CAD drawings, DEM, etc. With data collection made simple, you can focus your energy on analyzing
data, rather than working out how to gather it Less time spent on the ground means surveying team/staff’s safety is
improved by minimizing risk By acquiring faster data from the sky, you can gather millions of data points
in one short flight

SummaryNew trend - Drone technology may be the best cost-saving solution for aerial topography surveying and other data collection activities in landfill operationsand design.
It is fast and efficient solution for use in multiple sites. BRa operates 4 landfills in Argentina, each at about455 miles (1000km) apart.
Accuracy and easy use are key factors whenconsidering use of drone technology.
