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 ...
Geospatial Information Agency (Indonesian: Badan Informasi Geospasial, abbreviation: BIG) is the national mapping agency of Indonesia. BIG was formerly named National Coordinator for Survey and Mapping Agency (Indonesian: Badan Koordinasi Survei dan Pemetaan Nasional, abbreviation: Bakosurtanal).
Geovisualization is closely related to other visualization fields, such as scientific visualization [1] and information visualization. [2] Owing to its roots in cartography, geovisualization contributes to these other fields by way of the map metaphor, which "has been widely used to visualize non-geographic information in the domains of information visualization and domain knowledge ...
Web GIS has numerous functions, which can be divided into categories of Geospatial web services, including web feature services, web processing services, and web mapping services. [3] Geospatial web services are distinct software packages available on the World Wide Web that can be employed to perform a function with spatial data.
A spatial index is used by a spatial database to optimize spatial queries.Database systems use indices to quickly look up values by sorting data values in a linear (e.g. alphabetical) order; however, this way of indexing data is not optimal for spatial queries in two- or three-dimensional space.
[3] This is an early example of what has come to be known as disease diffusion mapping, an area of study based on the idea that a disease starts from some source or central point and then spreads throughout the local area according to patterns and conditions there. This is another area of research where the capabilities of a GIS have been shown ...
An 1858 multivariate map by Charles Joseph Minard, using a nominal choropleth to represent departments that supplied meat to be consumed in Paris, proportional circles to represent significant volumes of that meat, combined with pie charts dividing it into relative proportions of beef (black), veal (red), and mutton (green).
