Abstract:
Understanding of vector data models as used in GIS. Vector data provide a way to represent real world features within the GIS environment. A feature is anything you can see on the landscape such as houses, roads, trees, rivers, and so on. Each one of these things would be a feature when we represent them in a GIS Application. Vector features have attributes, which consist of text or numerical information that describes the feature. In this worksheet we expore the different geometry types used to represent vectors.
