georelational model A geographic data model that represents geographic features as an interrelated set of spatial and descriptive data. The georelational model is the fundamental data model used in ArcInfo.
spatial data models include the arc-node, georelational model, rasters or grids, and TINs). Multi-Spectral Scanner (MSS) 1. A device for capturing scanned data simultaneously at a variety of wavelengths;
2.
In this approach the georelational model is pulled round by defining the standardized geographic contents, database tables of the workspaces and layers and even the symbolization of each object type inside the layers.
Geographic features stored in a coverage typically reflect the same topic or theme. The coverage supports the georelational model, ...
Semantic components are defined by an attribution model, such as the georelational model typically used in current GISs, plus the collection of properties and their parameters associated with the feature.
The terms modeling and analysis are often used interchangeably, although the former is more limited in space.
2. Data representation of reality (e.g., spatial data models include the arc-node, georelational model, rasters or grids, and TINs).
