Analysis of Cartographic Generalization based on PYTHON Programming Language on Digital Topographic Maps

摘要

Cartographic generalization is a creative process of abstraction, which is used in the design and content preparation of topographic maps. It includes the study of the geographic environment, processing of geographic data, and an evaluation with regard to type, purpose, and scale of the map, or selecting and merging their graphical presentation, with a big or small degree of abstraction. In the era of digital cartography more attention is paid to developing tools for automatic generalization of cartographic content. In this paper, automatic cartographic generalization is analyzed based on PYTHON programming language for production of digital topographic map scale 1:50 000 (DTM50) from digital topographic map scale 1:25 000 (DTM25).
