Geomatics is the science and technology of gathering, analyzing, interpreting, distributing and using geographic information. Geomatics encompasses a broad range of disciplines that can be brought together to create a detailed but understandable picture of the physical world and our place in it. These disciplines include:
* remote sensing
* geographic information systems (GIS)
* global positioning system (GPS)
An emerging technology sector
Geomatics is one of the fastest-growing technology sectors of the 1990s - and Canada is at its forefront. Canada's geomatics community is a recognized world leader in providing the software, hardware and value-added services that can help clients address problems and opportunities in such areas as:
* the environment
* land management and reform
* development planning
* infrastructure management
* natural resource monitoring
* sustainable development
* coastal zone management and mapping

The mathematics of the earth; the science of the collection, analysis, and interpretation of data, especially instrumental data, relating to the earth's surface. (Oxford English Dictionary)
Geomatics Engineering is a modern discipline, which integrates acquisition, modelling, analysis, and management of spatially referenced data, i.e. data identified according to their locations. Based on the scientific framework of geodesy, it uses terrestrial, marine, airborne, and satellite-based sensors to acquire spatial and other data. It includes the process of transforming spatially referenced data from different sources into common information systems with well-defined accuracy characteristics.
A Geomatics Engineer uses knowledge coming from several disciplines, such as:
* Geodesy (terrestrial, celestial, and orbital coordinate systems measurements)
* Positioning and Navigation (e.g. with GPS)
* Digital Imaging (how to extract useful information from images according to the application, e.g. environmental studies or agricultural studies) and Mapping (how to make the maps of tomorrow) using Photogrammetry (airborne photographs) or Remote Sensing (images taken by satellite sensors)
* Geographical Information Systems(computer systems capable of assembling, storing, manipulating, and displaying geographically referenced information)
* Land Tenure Systems (land information managing, land surveying, land right).
Modelling spatial geometry, making observations and estimating spatial positions and their uncertainty is a key component of the Geomatics Engineering education. Since the world of Geomatics is constantly evolving, it is also essential to keep up with the rapid growth of the know-how, methods and tools of this interdisciplinary field.
