2. Geographic data and information - Wikipedia

   en.wikipedia.org/wiki/Geographic_data_and...

   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.

3. Geographic information system - Wikipedia

   en.wikipedia.org/wiki/Geographic_Information_System

   Depicted hardware (field-map technology) is used mainly for forest inventories, monitoring and mapping. GIS data acquisition includes several methods for gathering spatial data into a GIS database, which can be grouped into three categories: primary data capture, the direct measurement phenomena in the field (e.g., remote sensing, the global ...

4. Geospatial intelligence - Wikipedia

   en.wikipedia.org/wiki/Geospatial_intelligence

   Geospatial Intelligence data sources include imagery and mapping data, whether collected by commercial satellite, government satellite, aircraft (such as Unmanned Aerial Vehicles [UAV] or reconnaissance aircraft), or by other means, such as maps and commercial databases, census information, GPS waypoints, utility schematics, or any discrete ...

5. Data model (GIS) - Wikipedia

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

   The Mahomet Sand is continuous in this area, and represents one occurrence of this unit in the data model. Each raster, or pixel, on the Mahomet Sand surface has a set of map coordinates that are recorded in a GIS (in the data model bin that is labeled "pixel coordinates", which is the raster corollary of the "geometry" bin for vector map data).

6. Location intelligence - Wikipedia

   en.wikipedia.org/wiki/Location_intelligence

   In business intelligence, location intelligence (LI), or spatial intelligence, is the process of deriving meaningful insight from geospatial data relationships to solve a particular problem. [1] It involves layering multiple data sets spatially and/or chronologically, for easy reference on a map, and its applications span industries, categories ...

7. Spatial data infrastructure - Wikipedia

   en.wikipedia.org/wiki/Spatial_data_infrastructure

   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.

8. Web GIS - Wikipedia

   en.wikipedia.org/wiki/Web_GIS

   However, Web GIS and web mapping are distinct concepts, with web mapping not necessarily requiring a Web GIS. [ 5 ] The use of the Web has dramatically increased the effectiveness of both accessing and distributing spatial data, two of the most significant challenges of desktop GIS.

9. Spatial analysis - Wikipedia

   en.wikipedia.org/wiki/Spatial_analysis

   Geospatial and hydrospatial analysis, or just spatial analysis, [70] is an approach to applying statistical analysis and other analytic techniques to data which has a geographical or spatial aspect.
