Generalization has a long history in cartography as an art of creating maps for different scale and purpose. Cartographic generalization is the process of selecting and representing information of a map in a way that adapts to the scale of the display medium of the map. In this way, every map has, to some extent, been generalized to match the criteria of display.

Such thematic knowledge is then represented using the so-called production-rule method to become generalization rules. These rules are built in a prototype system to guide the implementation of land use data generalization. First I tried to consider this problem by a generalization. For p;q > 0 satisfying p+q = 1 de–ne sequences of numbers by a n+1 = pa n +qb n, b n+1 = a pbq, a 0 = a, b 0 = b, and expected to obtain its limit as an integral representation. Readers who are interested in the history of arithemetic-geometric mean will –nd an article in We give a solve a nice simple geometry problem with a connection to the harmonic mean.

Thematic and geometric generalization

2011-10-02 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 Generalization improves the map’s ability to communicate, i.e., its ability to convey information. In doing this, the main goal is to preserve geographic patterns and emphasize thematic information. Due to unavoidable generalization in cartography, the terms precision (positional and thematic) and thruthfulness are given new meaning.

In this way, every map has, to some extent, been generalized to match the criteria of display. generalization based on geometric transformation of edges of building models with the aim to reduce data volume from each LoD can be applied to associated geometries. For this purpose, four decades ago, research done on a set of generalization procedures in (Staufenbiel, 1973) for geometric transformation Generalization involves a great deal of human analysis of the geographic data and decisions on what to generalize, how to generalize, Refinement— Altering and adjusting a feature's geometry or appearance to improve its aesthetic (visual) impression and to ensure its agreement with reality.

The positional error for each geographical object is propagated through the process and a generalization error is also introduced by the generalization. Previous research has focused mainly on

Thematic knowledge describes the special restrictions and specifications for a specific geographic data or application. Generalization may be understood as a process of controlled distribution refinement affecting both the- matic and geometric domains [5]: attenuating a spatial pattern while retaining the most important elements for a given context and, moreover, preserving the character of the pattern. Map generalization is most clearly entailed in scale reduction. 2010-09-01 Adequate representation of cartographic expert knowledge is essential if maps are to be created in an automated way.

generalization of geographic data. Thematic knowledge describes the special restrictions and specifications for a specific geographic data or application.

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 authenticity. 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 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. supporting models play a key role in organizing thematic and geometric data, spatial analysis and spatial query in database generalization. It also proved that a lot of critical geometric and thematic problems in database generalization can be solved, or can be solved in a more efficient way, with the support of an adequate data model.
