A map analysis is a study regarding map types, i.e. political maps, military maps, contour lines etc., and the unique physical qualities of a map, [1] i.e. scale, title, legend etc. It is also a way of decoding the message and symbols of the map and placing it within its proper spatial and cultural context, as well as identifying changes in ...
Paper maps, which have been digitized for many years as a data source, can also be of widely varying quality. A quantitative analysis of maps brings accuracy issues into focus. The electronic and other equipment used to make measurements for GIS is far more precise than the machines of conventional map analysis.
During the first half of the 20th century, cartographers began to think seriously about how the features they drew depended on scale. Eduard Imhof, one of the most accomplished academic and professional cartographers at the time, published a study of city plans on maps at a variety of scales in 1937, itemizing several forms of generalization that occurred, including those later termed ...
The Odyssey project's aim was to produce a vector GIS that provided spatial analysis of many different forms within a single system. As of 1980, in addition to early Odyssey modules, the Laboratory sold the following programs for display and analysis of spatial data [11] ASPEX - 3d data perspectives; CALFORM - shaded vector maps;
A thematic map is a type of map that portrays the geographic pattern of a particular subject matter (theme) in a geographic area. This usually involves the use of map symbols to visualize selected properties of geographic features that are not naturally visible, such as temperature, language, or population. [1]
The light but non-white background color enables the use of white as a map symbol (the county boundary across the center). Also note the central box showing the location of a separate detail inset map. In addition to the map itself, there are various elements that are included in the map layout. The following are common elements of a map layout ...
Cartographic features are types of abstract geographical features, which appear on maps but not on the planet itself, even though they are located on the planet. For example, grid lines, latitudes , longitudes , the Equator , the prime meridian , and many types of boundary, are shown on maps of Earth, but do not physically exist.
