SIB Council on Geomatics (SIB-Gm)

Keywords:

Photogrammetry, active sensors, laser scanning, 3D modeling, surveying, remote sensing, Spatial Information Systems

Scope:

Consolidate the role of geomatics as leader discipline for the derivation of spatial, metric, accurate and semantic information from images or range data using passive and active sensors. Geomatics includes all the techniques dealing with surveying and measurement and hosts part of the graphics disciplines involved in the visualization of geo-spatial and geo-referenced data.

Key-Challenges:

- development of reliable, fast and cheap procedures for geomatics data acquisition;
- increasing the level of automation in the data processing;
- development of a powerful sensor integration strategy to combine range and image data to exploit the intrinsic potentials and advantages of each technique, compensate for the individual weaknesses of each method alone
- realization of advance repository systems and virtual platforms to collect and share information related to environment, landscape, archaeological sites, museums, etc.
- development of standards and protocols related to the 3D documentation, modeling and data conservation, as strongly requested by the international organization and committee like ASTM and VDI/VDE in the industrial and geomatics fields or UNESCO, ISPRS (International Society for Photogrammetry and Remote Sensing), ICOMOS (International Committee on Monuments and Sites), CIPA (International Committee for Architectural Photogrammetry), IAPR (International Association for Pattern Recognition) in the heritage field

Mission:

Work in the field of remote sensing, terrestrial and airborne photogrammetry as well as active sensors for accurate DTM/DSM generation, 3D documentation and visualization of large landscapes or heritage site or urban areas, damages and hazards mapping, structural analyses, industrial inspections, thermal dispersions identification and monitoring, decision supports and planning policies, maintenance and survey of roads or power lines, virtualization and musealization using 3D models, (geo-) morphological studies and visibility analyses, monitoring and analysis of forests, cadastral updating.

Description:

Geomatics, as a science for acquiring, processing, storing and delivering of geographic and spatially referenced (3D) information, is gathering more and more power as discipline for environment mapping and heritage documentation. Geomatics researchers rely on photogrammetry and remote sensing as optical image-based techniques for the extraction of metric and semantic information from images or on active sensors, like laser scanners, radar or stripe projection systems, which have the advantage of providing directly 3D information. All these available platforms, sensors and technologies set the scene for totally new approaches, methodologies and perspectives for recording, modeling, mapping and protection. Geomatics should assist government, research, industry and private parties to collect, structure, manage and visualize geospatial and metric information for general 3D modeling and reverse engineering problems, structural monitoring and recording or support in decision planning for roads, railways, airports and urbanization control and management.
