GIS data models are: 1. Data, Information, Knowledge, and Wisdom. The geometry and geography data types support sixteen spatial data objects, or instance types. A geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data. GIS software often hides geospatial data columns when viewing an attribute table, but for data formats based on other database software, like Geopackage (based on SQLite) or PostGIS (based on PostGreSQL), geospatial data can be readily seen as just another column in the table. Coordinate systems enable you to integrate datasets to perform various integrated analytical operations, such as overlaying data layers from disparate sources and coordinate systems. Under no circumstances should GIS products be used for final design purposes. 1 Definition GIS is a computer-based information system that enables capture, modeling, manipulation, retrieval, analysis and presentation of geographically referenced data.
