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.
Geographic information system (GIS) is a commonly used tool for environmental management, modelling and planning. As simply defined by Michael Goodchild, GIS is as "a computer system for handling geographic information in a digital form". [68] In recent years it has played an integral role in participatory, collaborative and open data philosophies.

Tampa (/ ˈ t æ m p ə / ⓘ TAM-pə) is a city on the Gulf Coast of the U.S. state of Florida. Tampa's borders include the north shore of Tampa Bay and the east shore of Old Tampa Bay. Tampa is the largest city in the Tampa Bay area and the county seat of Hillsborough County.
The history of Web GIS is very closely tied to the history of geographic information systems, Digital mapping, and the World Wide Web or the Web. The Web was first created in 1990, and the first major web mapping program capable of distributed map creation appeared shortly after in 1993.
A geoportal is a type of web portal used to find and access geographic information (geospatial information) and associated geographic services (display, editing, analysis, etc.) via the Internet. Geoportals are important for effective use of geographic information systems (GIS) and a key element of a spatial data infrastructure (SDI).
The earliest computer systems that represented geographic phenomena were quantitative analysis models developed during the quantitative revolution in geography in the 1950s and 1960s; these could not be called a geographic information system because they did not attempt to store geographic data in a consistent permanent structure, but were usually statistical or mathematical models.
The software component of a traditional geographic information system is expected to provide a wide range of functions for handling spatial data: [11]: 16 Data management, including the creation, editing, and storage of geographic data, as well as transformations such as changing coordinate systems and converting between raster and vector models.
