2. List of GIS data sources - Wikipedia

   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. Web Coverage Service - Wikipedia

   en.wikipedia.org/wiki/Web_Coverage_Service

   Unlike the OGC Web Map Service (WMS), which portrays spatial data as static, server-rendered images (maps), the Web Coverage Service delivers underlying data values along with their detailed descriptions. This enables a rich syntax for queries against the data and returns information with its original semantics, rather than just pictures ...

4. National Lidar Dataset (United States) - Wikipedia

   en.wikipedia.org/wiki/National_Lidar_Dataset...

   Currently, the best source for nationwide LiDAR availability from public sources is the United States Interagency Elevation Inventory (USIEI). [1] The USIEI is a collaborative effort of NOAA and the U.S. Geological Survey, with contributions from the Federal Emergency Management Agency, the Natural Resources Conservation Service, the US Army Corps of Engineers, and the National Park Service.

5. Geographic information system software - Wikipedia

   en.wikipedia.org/wiki/Geographic_information...

   A GIS software program is a computer program to support the use of a geographic information system, providing the ability to create, store, manage, query, analyze, and visualize geographic data, that is, data representing phenomena for which location is important.

6. Internet GIS - Wikipedia

   en.wikipedia.org/wiki/Internet_GIS

   The World Wide Web is an information system that uses the internet to host, share, and distribute documents, images, and other data. [33] Web GIS involves using the World Wide Web to facilitate GIS tasks traditionally done on a desktop computer, as well as enabling the sharing of maps and spatial data. [7]

7. Geodatabase (Esri) - Wikipedia

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

   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 ...

8. Web GIS - Wikipedia

   en.wikipedia.org/wiki/Web_GIS

   The scale of the Web can sometimes make finding quality and reliable data a challenge for GIS professionals and end users, with a significant amount of low-quality, poorly organized, or poorly sourced material available for public consumption. [13] [14] This can make finding spatial data a time consuming activity for GIS users. [13]

9. EPSG Geodetic Parameter Dataset - Wikipedia

   en.wikipedia.org/wiki/EPSG_Geodetic_Parameter...

   Most geographic information systems (GIS) and GIS libraries use EPSG codes as Spatial Reference System Identifiers (SRIDs) and EPSG definition data for identifying coordinate reference systems, projections, and performing transformations between these systems, while some also support SRIDs issued by other organizations (such as Esri).
