SAS/GIS 9.2 Spatial Data and Procedure Guide

A data model may be defined as the objects in a spatial database plus the rela-tionships among them. The term model is fraught with ambiguity, because it is used in many disciplines to describe many things. Here the purpose of a spatial data model is to provide a formal means of representing and manipulating spatially-referenced informa-tion. In our lake example our data model consists of two

Monitoring Data in Model Verification). The role of a GIS is to enable the capture, storage, and manipulation of data in a structured form, therefore allowing the use of analytical techniques on the spatial dimensions of problems. With a GIS, analysis and depiction of spatially referenced information as well as dissemination of results of analysis using thematic maps is possible. Environmental

spatial data an overview ScienceDirect Topics

Spatial data can represent Vector and Raster Data Models real-world features that have discrete boundaries (such as roads, buildings, lakes, rivers, administrative boundaries) as well as real-world phenomena/features that have non-discrete boundaries (such as precipitation and nutrient levels, terrain). In general, the vector data model is used to represent the former and the raster data

Several different vector data models exist, however only two are commonly used in GIS data storage. 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.

In a database-oriented GIS, spatial and textual data can be stored and linked using the geo-relational model. Current GIS support ef?cient data retrieval, query, and mapping. Planners can also extract data from their databases and input them to other modelling and spatial analysis programs. When combined with data from other tabular databases or specially conducted surveys, geographical
