[ 1 ] [ 2 ] A geodatabase is both a logical data model and the physical implementation of that logical model in several proprietary file formats ...
GIS data acquisition includes several methods for gathering spatial data into a GIS database, which can be grouped into three categories: primary data capture, the direct measurement phenomena in the field (e.g., remote sensing, the global positioning system); secondary data capture, the extraction of information from existing sources that are ...
A Land Information System (LIS) is a geographic information system for cadastral and land-use mapping, typically used by local governments. [1]A LIS consists of an accurate, current and reliable land record cadastre and its associated attribute and spatial data that represent the legal boundaries of land tenure and provides a vital base layer capable of integration into other geographic ...

The AM/FM/GIS system data model allow GIS architects to define a relationship model which consists of all the database tables and their dependencies. This is often combined with business rules to make the system more intelligent so that it can be utilized in running various analysis on the data. E.g. a gas pipeline GIS system can let the users ...
Web GIS (also known as Web-Based GIS), or Web Geographic Information Systems, are GIS that employ the World Wide Web to facilitate the storage, visualization, analysis, and distribution of spatial information over the Internet.
