Why Geospatial Information?

  • Geospatial, and in general geographical, informationis very important in reality: everything that happens, happens somewhere (location).

  • Decision making can be substantially improved if we know where things take place.

Geography

  • From http://en.wikipedia.org/wiki/Geography

    • Geography is the science that studies the lands, the features, the inhabitants and the phenomena of the Earth.

    • From the Greek word γεωγραφία (geographia) which means “describing the Earth”.

Geographical Information Systems and Science

  • A geographical information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data.

  • GIS science is the field of study for developing and using GIS.

Why this tutorial?

  • Lots of geospatial data is available on the Web today.

  • Lots of public data coming out of open government initiatives is geospatial.

  • Lots of this public data is quickly being transformed into linked data!

  • People have started building applications utilizing linked data.
