What is a Geographical Information System (GIS) (4/4)

This final video in a four-part series looks at how a GIS enables us to solve problems (for instance calculating noise buffers). It looks at the types of questions we could pose to a GIS (queries). It asks who might find a GIS useful? Finally the presenter summarises the content he covered in his course (i.e. all four videos) particularly with respect to questions that might come up in an exam paper.
