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

By Zhilin Li

With the common use of GIS, multi-scale illustration has develop into a tremendous factor within the realm of spatial info dealing with. although, no e-book thus far has systematically tackled the various points of this self-discipline. Emphasizing map generalization, Algorithmic beginning of Multi-Scale Spatial illustration addresses the mathematical foundation of multi-scale illustration, in particular, the algorithmic foundation.

Using easy-to-understand language, the writer makes a speciality of geometric changes, with every one bankruptcy surveying a specific spatial characteristic. After an advent to the fundamental operations required for geometric modifications in addition to a few mathematical and theoretical historical past, the e-book describes algorithms for a category of aspect features/clusters. It then examines algorithms for person line gains, resembling the aid of knowledge issues, smoothing (filtering), and scale-driven generalization, by way 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 region good points, a category of region gains, and numerous displacement operations. the ultimate bankruptcy in brief covers algorithms for three-D surfaces and three-D features.

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