    en.wikipedia.org/wiki/List_of_GIS_data_sources

    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.

  3. Geographic information system - Wikipedia

    en.wikipedia.org/wiki/Geographic_Information_System

    The core of any GIS is a database that contains representations of geographic phenomena, modeling their geometry (location and shape) and their properties or attributes. A GIS database may be stored in a variety of forms, such as a collection of separate data files or a single spatially-enabled relational database. Collecting and managing these ...

  4. Data model (GIS) - Wikipedia

    en.wikipedia.org/wiki/Data_model_(GIS)

    The georelational data model was the basis for most early vector GIS software. [19] The geometric data and the attribute data are stored separately; this was originally because the geometric data required GIS-specific code to process it, but existing relational database software (RDBMS) could be

  7. Geodatabase (Esri) - Wikipedia

    en.wikipedia.org/wiki/Geodatabase_(Esri)

    The origin of the geodatabase was in the mid-1990s during the emergence of the first spatial databases.One early approach to integrating relational databases and GIS was the use of server middleware, a third-party program that stores the spatial data in database tables in a custom format, and translates it dynamically into a logical model that can be understood by the client software.

    There are also many different types of geodata, including vector files, raster files, geographic databases, web files, and multi-temporal data. Spatial data or spatial information is broader class of data whose geometry is relevant but it is not necessarily georeferenced , such as in computer-aided design (CAD), see geometric modeling .
