GIS stands for Geographic Information System, which is a computer system that allows users to collect, store, manage, and analyze geographic data.

Users are not a component of GIS. GIS is a computer system that consists of hardware, software, and data.

Remote sensing is the process of acquiring information about an object or area from a distance without being in physical contact with it.

GPS is a global positioning system, not a type of remote sensing data.

GPS stands for Global Positioning System, which is a satellite-based navigation system that provides location and time information.

Medical diagnosis is not an application of GIS. GIS is used in various fields such as land use planning, environmental management, and transportation planning.

Cartography is the process of creating a map, which is a symbolic representation of an area.

GPS is a global positioning system, not a type of map projection.

Reprojection is the process of converting geographic data from one coordinate system to another.

GPS data is not a type of geospatial data. Geospatial data includes vector data, raster data, and attribute data.

Geodatabase is a database that stores geographic information.

GPS analysis is not a type of geospatial analysis. Geospatial analysis includes buffer analysis, overlay analysis, and network analysis.

3D GIS is the process of creating a 3D representation of a geographic area.

Cartography is not a type of geospatial technology. Geospatial technologies include GIS, remote sensing, and GPS.
