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.
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 ...
The actual shapefile relates specifically to the .shp file, but alone is incomplete for distribution as the other supporting files are required. In line with the ESRI Shapefile Technical Description , [ 1 ] legacy GIS software may expect that the filename prefix be limited to eight characters to conform to the DOS 8.3 filename convention ...
A spatial data infrastructure (SDI), also called geospatial data infrastructure, [1] is a data infrastructure implementing a framework of geographic data, metadata, users and tools that are interactively connected in order to use spatial data in an efficient and flexible way.
A GIS file format is a standard for encoding geographical information into a computer file, as a specialized type of file format for use in geographic information systems (GIS) and other geospatial applications. Since the 1970s, dozens of formats have been created based on various data models for various purposes
A Geodatabase is a proprietary GIS file format developed in the late 1990s by Esri (a GIS software vendor) to represent, store, and organize spatial datasets within a geographic information system. [ 1 ] [ 2 ] A geodatabase is both a logical data model and the physical implementation of that logical model in several proprietary file formats ...
It is a tool for visualizing and processing spatial data, characterized by its friendly user interface and access to multiple data formats, both vectorial (in a file, such as Shapefile, GML, KML, DWG and DXF, or a database, such as PostgreSQL, MySQL, or Oracle) and raster (TIFF, ECW, MrSID, or other georeferenced image files, such as BMP, GIF ...
