3D Remote Sensing

The three-dimensional shape of the Earth has become of major importance for several remote sensing applications in the last years, thanks to the continuously increased ground resolution of optical and radar sensors.

Topics like the geometrical correction of the remote sensed imagery through models for image orientation and geo-referencing and the discrete 3-D representation of the surface of the Earth through Digital Surface, Elevation and Terrain Models (DSMs, DEMs, DTMs) based on remotely sensed imagery are of primary importance.

The discrete 3-D representation of the surface of the Earth is a basis for a large and increasing variety of applications in Engineering, Earth and Environmental Science, Safety and Security (terrain analysis, flood prediction, coastal mapping, erosion control, determination of subsidence, noise and gas propagation, telecommunications planning, …), so that methodologies and technics related to the different steps of DSMs, DEMs and DTMs generation and quality control are in the centre of the SIG 3D Remote Sensing.

The SIG strongly encourages both the cooperation with other international associations involved in similar topics as ISPRS, ASPRS, IEEE-GRSS, IAG and the networking and technology transfer among the academia and professionals, government entities and industry which are involved in remote sensing research and applications at European level and beyond.
