Raster data model Study guides, Class notes & Summaries

Data Model - correct answer Data models are a set of rules and/or constructs used to describe and represent aspects of the real world in a computer. Two primary data models are available to complete this task: raster data models and vector data models. Spatial Data - correct answer Spatial data is usually stored as coordinates and topology, and is data that can be mapped. Spatial data is often accessed, manipulated or analyzed through Geographic Information Systems Raster Data - correct an...
