Cartographic generalization is the process of controlling the amount of detailed information portrayed in a map.This also includes using the appropriate scale, purpose, and medium of the map.This form of Generalization commonly consists of reducing the visual detail of data by reducing the map scale when the map purpose suggests the need for a simpler design. Short before the end of the first version we started the design of the second one with changes and enhancements in the data model. Hung Hom, Kowloon, Hong Kong SAR, PRC (ChristopherGold@Voronoi.Com) David Thibault . 11. Generalization as a general human activity is first considered in a broad context and map generalization is defined as a special variant of spatial modelling. MAP GENERALIZATION BY SKELETON RETRACTION . It follows from the analysis that, in the process of designing a mid-scale topographic map, we are dealing with five basic types of generalization, which With the advent of new data acquisition techniques, particularly remote sensing, data sources for spatial analysis have greatly increased. One of NCGIA's research initiatives is "Formalizing Cartographic Knowledge." More practical, all roads of the same classification have identical representation on specific scale (throughout whole domain), which is easy for map reading (at this fixed scale). Categorical data are a frequent data type in GIS and thematic cartography. maps themselves one can compare the scope of their content as well as the representational techniques used, and be able to define the practical nature of topographic map generalization.
