Geodemography has been used to target consumer services to 'ideal' populations based on their lifestyle and location. These parameters have been taken from geographical databases as well as from electoral lists and credit agencies. Combining these builds a picture of the population characteristics in different locations.
The use of different algorithms leads to different results, but there is no single best approach for selecting the best algorithm, just as no algorithm offers any theoretical proof of its certainty. [1] One of the most frequently used techniques in geodemographic segmentation is the widely known k-means clustering algorithm. In fact most of the ...
The distinction must be made between a singular geographic information system, which is a single installation of software and data for a particular use, along with associated hardware, staff, and institutions (e.g., the GIS for a particular city government); and GIS software, a general-purpose application program that is intended to be used in ...
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.
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.
Participatory GIS (PGIS) or public participation geographic information system (PPGIS) is a participatory approach to spatial planning and spatial information and communications management. [1] [2] PGIS combines Participatory Learning and Action (PLA) methods with geographic information systems (GIS). [3]
A local information system (LIS) is a form of information system built with business intelligence tools, designed primarily to support geographic reporting. They overlap with some capabilities of geographic information systems (GIS), although their primary function is the reporting of statistical data rather than the analysis of geospatial data .
Demographic targeting is a form of behavioral advertising in which advertisers target online advertisements at consumers based on demographic information. [1]They are able to achieve this by using existing information from sources such as browser history, previous searches as well as information provided by the users themselves to create demographic profiles of consumers.
