Physical map of Earth Political map of Earth. A map is a symbolic depiction of interrelationships, commonly spatial, between things within a space. A map may be annotated with text and graphics. Like any graphic, a map may be fixed to paper or other durable media, or may be displayed on a transitory medium such as a computer screen.
Another example of early thematic mapping comes from London physician John Snow. Though disease had been mapped thematically, Snow's cholera map in 1854 is the best-known example of using thematic maps for analysis. Essentially, his technique and methodology anticipated the principles of a geographic information system .
An example of the range of geocritical practices can be found in Tally's collection Geocritical Explorations: Space, Place, and Mapping in Literary and Cultural Studies. Geocriticism derives some of its practices from precursors whose theoretical work helped establish space as a valid topic for literary analysis.
Spatial analysis confronts many fundamental issues in the definition of its objects of study, in the construction of the analytic operations to be used, in the use of computers for analysis, in the limitations and particularities of the analyses which are known, and in the presentation of analytic results.
A couple of examples might be a dot map showing corn production in Indiana or a shaded area map of Ohio counties, divided into numerical choropleth classes. As the volume of geographic data has exploded over the last century, thematic cartography has become increasingly useful and necessary to interpret spatial, cultural and social data.
For example, the answer to the famous question "How Long Is the Coast of Britain" is highly dependent on the choice of cartographic scales. In cartography and spatial analysis, scale effect and zoning effect (different ways of zoning lead to different statistical outcomes) combined can lead to modifiable areal unit problem (MAUP). [2]
The spatial or locational tradition is concerned with employing quantitative methods to describe the spatial characteristics of a location. [1] [2] [5] The spatial tradition seeks to use the spatial characteristics of a location or phenomena to understand and explain it. The contributors to this tradition were historically cartographers, but it ...
Numerous examples of LBS user-level software packages (applications), exist which require the ability to leverage spatial contextual awareness. These applications are in demand by the general public and are examples of how maps are being used by individuals to help better understand the world and make daily decisions. [5]
