Download PDF by Zhilin Li: Algorithmic Foundation of Multi-Scale Spatial Representation

By Zhilin Li

With the common use of GIS, multi-scale illustration has develop into an immense factor within the realm of spatial info dealing with. although, no publication so far has systematically tackled different elements of this self-discipline. Emphasizing map generalization, Algorithmic starting place of Multi-Scale Spatial illustration addresses the mathematical foundation of multi-scale illustration, particularly, the algorithmic foundation.

Using easy-to-understand language, the writer specializes in geometric changes, with every one bankruptcy surveying a selected spatial function. After an advent to the fundamental operations required for geometric modifications in addition to a few mathematical and theoretical history, the booklet describes algorithms for a category of aspect features/clusters. It then examines algorithms for person line good points, equivalent to the relief of information issues, smoothing (filtering), and scale-driven generalization, by means of a dialogue of algorithms for a category of line positive aspects together with contours, hydrographic (river) networks, and transportation networks. the writer additionally addresses algorithms for person zone positive factors, a category of zone positive factors, and numerous displacement operations. the ultimate bankruptcy in brief covers algorithms for 3-D surfaces and 3D features.

Providing an intensive remedy of low-level algorithms, Algorithmic beginning of Multi-Scale Spatial illustration offers the mathematical basis for multi-scale representations of spatial data.
