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 ...
This is a list of GIS data sources (including some geoportals) that provide information sets that can be used in geographic information systems (GIS) and spatial databases for purposes of geospatial analysis and cartographic mapping. This list categorizes the sources of interest.
The distinction must be made between a singular geographic information system, which is a single installation of software and data for a particular use, along with associated hardware, staff, and institutions (e.g., the GIS for a particular city government); and GIS software, a general-purpose application program that is intended to be used in ...
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 ...
An assessor's parcel number, or APN, is a number assigned to parcels of real property by the tax assessor of a particular jurisdiction for purposes of identification and record-keeping. The assigned number is unique within the particular jurisdiction, and may conform to certain formatting standards that convey basic identifying information such ...
Geospatial metadata (also geographic metadata) is a type of metadata applicable to geographic data and information.Such objects may be stored in a geographic information system (GIS) or may simply be documents, data-sets, images or other objects, services, or related items that exist in some other native environment but whose features may be appropriate to describe in a (geographic) metadata ...
Geographic information systems (GIS) play a constantly evolving role in geospatial intelligence (GEOINT) and United States national security.These technologies allow a user to efficiently manage, analyze, and produce geospatial data, to combine GEOINT with other forms of intelligence collection, and to perform highly developed analysis and visual production of geospatial data.
A land-parcel identification system (LPIS) is a system to identify land use for a given country. [1] It utilises orthophotos; aerial photographs and high precision satellite images that are digitally rendered to extract as much meaningful spatial information as possible. A unique number is given to each land parcel to provide unique ...
