Geomatique

Geomatique, often written géomatique in French-speaking contexts, is the multidisciplinary field concerned with the collection, management, analysis, and dissemination of geographic information. It integrates elements of geodesy, surveying, geographic information science (GIScience), cartography, photogrammetry, and remote sensing to support decision making and spatial understanding. The field covers both scientific methods and practical applications for handling location-based data.

Core components include data acquisition, data management and metadata, spatial analysis, and visualization. Acquisition methods involve GNSS (Global Navigation Satellite Systems), surveying instruments, photogrammetry, and remote sensing with satellite and airborne sensors. Data management focuses on geodatabases, data standards, and metadata to ensure interoperability. Spatial analysis encompasses query, modeling, and geographic reasoning, while visualization emphasizes maps, 3D representations, and web GIS for dissemination.

Technologies and tools commonly used in geomatique include GIS software (such as QGIS and ArcGIS), remote sensing platforms, LiDAR, and web mapping technologies. Standards and infrastructure play a key role, with organizations developing and maintaining specifications for data formats, services, and interoperability (for example OGC standards and ISO 191xx series).

Applications span urban planning, environmental monitoring, natural resource management, agriculture, transportation, disaster management, and public health. Education in geomatique is offered at universities through programs in surveying, geography, civil engineering, and GIScience. Professional practice varies by jurisdiction, with licensure and associations encouraging ethical data use and quality control.
