Zhilin Li's Algorithmic Foundation of Multi-Scale Spatial Representation PDF

By Zhilin Li

With the common use of GIS, multi-scale illustration has turn into an immense factor within the realm of spatial info dealing with. even if, no publication to this point has systematically tackled the several elements of this self-discipline. Emphasizing map generalization, Algorithmic origin of Multi-Scale Spatial illustration addresses the mathematical foundation of multi-scale illustration, particularly, the algorithmic foundation.

Using easy-to-understand language, the writer makes a speciality of geometric ameliorations, with every one bankruptcy surveying a selected spatial function. After an advent to the basic operations required for geometric variations in addition to a few mathematical and theoretical history, the e-book describes algorithms for a category of element features/clusters. It then examines algorithms for person line beneficial properties, reminiscent of the aid of information issues, smoothing (filtering), and scale-driven generalization, by way of a dialogue of algorithms for a category of line positive factors together with contours, hydrographic (river) networks, and transportation networks. the writer additionally addresses algorithms for person zone positive factors, a category of sector positive factors, and numerous displacement operations. the ultimate bankruptcy in brief covers algorithms for 3-D surfaces and 3-D features.

Providing a radical remedy of low-level algorithms, Algorithmic beginning of Multi-Scale Spatial illustration provides the mathematical foundation for multi-scale representations of spatial data.
