APEI : Aerial surveys

APEI is a company at the forefront of technology specializing in the acquisition of geographic data and mapping by airborne means, using innovative techniques and equipment.

Our 4 aircrafts can embark our 6 sensors: 2 digital cameras DMC and 2 analogic cameras RC30, our thermographic sensor FLIR (SC5600) and our LIDAR LIDAR LIDAR (Light Detection And Ranging) is an optical remote sensing technology that measures properties of scattered light to find range and/or other information of a distant target. The prevalent method to determine distance to an object or surface is to use laser pulses. Like the similar radar technology, which uses radio waves, the range to an object is determined by measuring the time delay between transmission of a pulse and detection of the reflected signal.

The main applications of these photos are aerial mapping, GIS GIS Geographic Information system ; geographical and alike database concerning a specified region. , photogrammetry, thermography (thermo-maps) and the production of DEM DEM The term Digital Elevation Model represents height information of an area without any further definition about the surface. DEMs are used often in geographic information systems, and are the most common basis for digitally-produced relief maps. .
