Laboratory for Research in Applied Geomatics

The term “geomatics” has evolved from two disciplines : geography and informatics (computer science), to designate the combination of both into a new scientific field for the data processing of geographic information. More precisely, this includes the acquisition, management, analysis and distribution of geographic data in print or online.

In fact, the field of geomatics refers to a wide range of skills such as those associated, for example, with geodesy or photogrammetry. Others are derived from the computer sciences used to develop geolocalized data management and analysis tools : the GIS (Geographic Information Systems). Still others can be found at the intersection of geography and thematic fields of application, requiring GIS tools to study and resolve issues of spatial analysis in territorial management, sustainable development, transportation, health care, marketing, agriculture, education, etc. The objective of the Laboratory for Research in Applied Geomatics (LGA), in support of our school, the ENSG, is to contribute to the development of geomatics and its applications. Based on the ENSG skills pool, the LGA depends on its expertise in the most technical areas of the field : data acquision (topometry, geodesy, photogrammetry, image processing), computer science applied to GIS (programming, database management, web publishing, etc), spatial data analysis and its representation.

LGA’s focus on geomatics as a “computer-assisted decision-making tool”

The area chosen by the LGA to develop its research is geomatics as a “computer-assisted decision-making tool”, which means using geomatics tools to make it easier to take decisions on geolocalized problems, by providing expertise in data management and analysis and requiring state-of-the-art skills in the technical areas mentioned above. In addition to the research carried out in these technical fields (geodesy, photogrammetry, etc.), the LGA also contributes to the development of methods in spatial definition based on morphology and topology analyses.

These new data constructs designed as indicators will be introduced into GIS tools and thematic applications. The LGA will also participate in jointly organized research projects on various subjects..

More precisely, research projects carried out at the LGA will fall under the following categories :
- geographic data acquisition and management ;
- spatial definition of geographic information, Artificial Geographic Intelligence ;
- the analysis of spatial components in thematic applications.

A great permeability between different research projects is to be expected ; theoretical research projects should be allowed to inspire applied research projects which can then be implemented through LGA’s partnerships.
