In this section, we explain some of the concepts and expressions used on this site.
GeomaticsGeomatics, also known as geospatial technology or geomatics engineering, or geomatic engineering, is the discipline of gathering, storing, processing, and delivering geographic information, or spatially referenced information. In other words, it consists of products, services and tools involved in the collection, integration and management of geographic data.
Geospatial analysis is an approach to applying statistical analysis and other informational techniques to data which has a geographical or geospatial aspect. Such analysis would typically employ software capable of geospatial representation and processing, and apply analytical methods to terrestrial or geographic datasets, including the use of geographic information systems and geomatics.
GeoreferenceTo georeference means to associate something with locations in physical space. The term is commonly used in the geographic information systems field to describe the process of associating a physical map or raster image of a map with spatial locations. Georeferencing may be applied to any kind of object or structure that can be related to a geographical location, such as points of interest, roads, places, bridges, or buildings.
NIRInfrared: 0.7 to 300 µm wavelength. This region is further divided into the following bands:
Near Infrared (NIR): 0.7 to 1.5 µm.
Short Wavelength Infrared (SWIR): 1.5 to 3 µm.
Mid Wavelength Infrared (MWIR): 3 to 8 µm.
Long Wanelength Infrared (LWIR): 8 to 15 µm.
Far Infrared (FIR): longer than 15 µm.
The NIR and SWIR are also known as the Reflected Infrared, referring to the main infrared component of the solar radiation reflected from the earth\’s surface. The MWIR and LWIR are the Thermal Infrared.
