The World GIS Day, celebrated on 14th November every year, offers everyone a chance to learn more about the fascinating field of Geographic Information Systems and how GIS is part of our everyday lives today. GIS (Geographic Information Systems) are a set of computer-based tools used to collect, combine and overlay information in the form of easily understood maps constructed from up-to-date satellite images and field data, while remote sensing is the collection of information about the earth from a distance. |
