Generalization is not new to these areas of cartography, and has in fact always been involved in thematic geographic visualization, despite rarely being acknowledged. We illustrate this involvement with several examples of famous, public-audience thematic maps, noting the generalization procedures involved in drawing each, both across their basemap and thematic layers.

A series of geometric measures were designed to evaluate the changes produced by simplification. Thus for certain mapping tasks, such as in thematic cartography, other routines such as LANG tolerancing appear more appropriate. 1987 The Ohio State University.

We use a relatively unique typology here, namely that of Roth, Brewer, and Stryker because, in addition to providing clear definitions of each operator named, this typology approaches the suite of generalization techniques more holistically in that it includes thematic filtering, changes in graphic variables, and variations in textual elements, as well as geometric changes, as parts of the generalization process, all being constrained by map resolution and legibility .

Merchantc, Henry Bulleyc aRaytheon Corporation, USGS, EROS Data Center, Sioux Falls, SD 57198, USA 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. A third type of map is known as an "orienteering," or special purpose map. This type of map falls somewhere between thematic and general maps. 2001-10-01 · Meanwhile, other radiometric and geometric artifacts that will be discussed are especially relevant to Landsat 5 Thematic Mapper (TM) and Landsat 7 Enhanced Thematic Mapper Plus (ETM+) data.

The generalization of area features is a very important topic in digital map generalization, particularly in thematic map generalization. The operations used in area generalization, will cause changes in the geometry and thematic attributes of area features and the topological relationships between them. Thematic map generalization is based on geometry and geography. In terms of geometry, the shape and size of cartographic objects are simplified comprehensively, and in terms of geo-rationality, the thematic contents are summarized comprehensively. Cartographic synthesis is the close combination of geometric correctness and geographical Thematic constraints may jects, ~) specializations (rules) specifying the compo- be ranked by nominal, oder, interval and ratio, but nent types of the txxnponent objects building an can not be measured.

Newly created sub-triangles help to reproduce the isocontours (right). 4.2 Cell-Based Geometric Generalization This generalization technique (GLANDER & DÖLLNER 2009) generalizes a given virtual 3D Generalization of Arithmetic and Geometric Here, in contrast to thematic generalization, geometric transforma-tions of the data are applied. This is valid for both vector and raster data since although, in principle, raster data is gen-eralized by reclassifying cells, the concepts on how to do this rely on (discrete) geometrical transformations. Process In databases, generalization means information abstraction, the suppression of detail in order to widen the meaning of the information [6].

Universal Themes and Generalizations Universal Themes falls under the category of acceleration for GATE Standards, pushing students above and beyond the core content. Universal themes and generalizations are tools used to help build flexible thinking, make connections across broad, seemingly unrelated things, and create a structure for Although cartographers can use data sets in different ways to create thematic maps, five thematic mapping techniques are used most often: The most common is the choropleth map, which portrays quantitative data as a color and can show density, percent, average value, or quantity of an event within a geographic area.
