To visualize natural phenomena, one must first determine how to represent geographic space best. Data models are rules and constructs used to describe and represent aspects of the world on a computer. Two primary data models are available to complete this task: raster data models and vector data models.
Learning Outcomes
- Explain how raster data models are implemented in geographic information systems applications.
- Describe how vector data models are implemented in geographic information systems applications.
- Determine how satellite imagery, aerial photography, and unmanned aerial systems are implemented in geographic information systems applications.
