A dot distribution map (or a dot density map or simply a dot map) is a type of thematic map that uses a point symbol to visualize the geographic distribution of a large number of related phenomena. Dot maps are a type of unit visualizations that rely on a visual scatter to show spatial patterns, especially variances in density.
Geographic information retrieval (GIR) or geographical information retrieval systems are search tools for searching the Web, enterprise documents, and mobile local search that combine traditional text-based queries with location querying, such as a map or placenames.
ZIP codes are not truly areas, but rather a group of deliverable addresses. [2] Some or all of an existing ZIP code's addresses may be reassigned to a new ZIP if there is sufficient growth within a given postal ZIP Code. As many as 3% of ZIP codes undergo change each quarter. Thus, the 5-digit ZCTAs are of limited value in areas of growth or ...
Geographic information science (GIScience, GISc) or geoinformation science is a scientific discipline at the crossroads of computational science, social science, and natural science that studies geographic information, including how it represents phenomena in the real world, how it represents the way humans understand the world, and how it can be captured, organized, and analyzed.
The categorization of technical geography in the EOLSS as a branch is expanded upon by Ionel Haidu in his 2016 paper What is technical geography as being a consequence of cartography shifting from simply producing maps to producing spatial information, influenced by a culmination of information theory and technology like the World Wide Web.

Geostatistics is a branch of statistics focusing on spatial or spatiotemporal datasets.Developed originally to predict probability distributions of ore grades for mining operations, [1] it is currently applied in diverse disciplines including petroleum geology, hydrogeology, hydrology, meteorology, oceanography, geochemistry, geometallurgy, geography, forestry, environmental control, landscape ...
It will still cost you an average of $1 million or more to buy a home in 10 ZIP codes in the region. A newly-updated map with data from June shows the average home value for every community ...
Therefore, the association between variables depends on the size of areal units for which data are reported. Generally, correlation increases as areal unit size increases. The zoning effect describes variation in correlation statistics caused by the regrouping of data into different configurations at the same scale (areal shape). [8]
