What is GIS?

Geographic Information Systems (GIS) are systems most frequently implemented using computer software that can open, store, analyze, manipulate, and manage spatial or geographic data. The term "spatial" indicates any abstracted space that could be measured, while geographic means specifically dealing with representations of Earth. Geographic Information System tools allow for user-generated searches, analysis of spatial information, editing of data, and displaying the results of these operations. The acronym GIS is interchangeably used to mean Geographic Information Systems and Geographic Information Science, the latter being the underlying scientific principles of how Geographic Information Systems operate.
