Geospatial Analysis & GIS Research Group

Be special. Think Geospatial !!

Welcome to GeoCHOROS, the website of the Geospatial Analysis and GIS Research Group (GAGIS-RG) at the National Technical University of Athens. The Group focuses on research and education with regards to Geographical and Spatial Analysis, Geographic Information Systems (GIS) as well as Locational Planning and Location – Allocation Models. 

Geospatial analysis refers to the use of geographic data to identify information that is referenced to geography and that can also be referenced to time. More specifically, geospatial analysis is the manipulation of data based on location. This kind of analysis uses tools including geographic information systems (GIS), global positioning systems (GPS), georeferencing, metadata (“data about data”), and remote sensing. It can be used, for example, to probe the distribution of an air pollution event such as the accidental release of radioactive material or another toxic substance into the air, and to reveal contaminated wells in a region in an investigation of the contamination of groundwater.

Our website is intended to provide information about research, education, and outreach activities of the GAGIS-RG to public and private organizations, students, and geospatial planning professionals.
