This website is a campaign launched by ESRI Ireland to promote the value that GIS is bringing to organisations on the island of Ireland. Each month, we will be publishing case studies that highlight the enormous variety of maps and geographic analysis that are being created every day using GIS technology.
Simply put, a Geographical Information System combines and visualises spatial layers of information about a place to give you a better understanding of events at that location. What layers of information you combine depends on your purpose - finding the best location for a new store, analysing environmental damage, and so on.
