Raster. A raster model, otherwise known as a raster dataset (image), is, in its simplest form, a matrix (grid) of cells. Learn more about the raster data model So, with a simple data model, adjacencies and overlaps are not stored in the data and we have redundancies in our dataset. The simple data model is sometimes referred to as the spaghetti data model. I'm not making this up, that's an actual term in GIS. GIS has five layers, which are spatial reference framework, spatial data model, spatial data acquisition systems, spatial data analysis, and geo-visualization.

Effect of spatial scale and latitude on diversity–disease

The topologic data structure is often referred to as an intelligent data structure because spatial relationships between geographic features are easily derived when using them. Primarily for this reason the topologic model is the dominant vector data structure currently used in GIS technology. 2017-02-06 2017-05-02 II.

Two representational models are dominant; raster (grid-based) and vector (line-based): Raster. Chapter 4 Data Models for GIS 4.1 Raster Data Models. The objective of this section is to understand how raster data models are implemented in GIS 4.2 Vector Data Models. The objective of this section is to understand how vector data models are implemented in GIS 4.3 Satellite Imagery and Geospatial Data Models. A data model is a way of defining and representing real world surfaces and characteristics in GIS. There are two primary types of spatial data models: Vector and Raster. Vector data represents features as discrete points, lines, and polygons ; Raster data represents features as a rectangular matrix of square cells (pixels) Data models are a set of rules and/or constructs used to describe and represent aspects of the real world in a computer. In GIS, a set of data models are used for various applications.
