In their day, aerial solutions were a major innovation and land surveying professionals have relied on them for decades but now UAVs are the new disruptive technology.

Since 2011, we have provided professional surveyors with dedicated hardware. Whenever controlled accuracy is required, engineering grade sensors and GNSS-RTK capabilities have a definite edge over entry level consumer cameras and traditional GPS devices.

Get the Z right: methodology for achieving centimetre accuracy using drone-acquired data for mapping and topography purposes” is the title of our last White Paper which describes the results that can be attained with our UAVs and the methodology needed to achieve this. It has been presented at numerous international exhibitions (Geobusiness in London, RPAS Conference in Brussel, Géomètre-Expert in Nancy, among others).
