Each type of service in surveying requires specific accuracy. The higher the accuracy, the higher the requirements and the equipaments and the skills of the professionals. The Direct Georeferencing System allows the UAV to do any aerophotogrametry service with precision and accuracy better than 5 cm in small or large areas without Ground Control Points (GCPs), bringing advantages over the traditional topography methodologies.

Novarum Sky developed the innovative software EtherCopter for inspection services and professional aerial photography with UAVs. 

With 3D mapping of power lines using Direct Georeferencing (DG) and photogrammetry it is possible to carry out detailed analysis of areas with potential risk of accidents due to proximity to power lines.
