## Topological Data Structures for Surfaces: An Introduction to Geographical Information ScienceIn Geography and GIS, surfaces can be analysed and visualised through various data structures, and topological data structures describe surfaces in the form of a relationship between certain surface-specific features. Drawn from many disciplines with a strong applied aspect, this is a research-led, interdisciplinary approach to the creation, analysis and visualisation of surfaces, focussing on topological data structures.
- Provides GI scientists and geographers with an accessible overview of current surface topology research.
- Algorithms are presented and explained with practical examples of their usage.
- Features an accompanying website developed by the Editor - http://geog.le.ac.uk/sanjayrana/surface-networks/
This book is invaluable for researchers and postgraduate students working in departments of GI Science, Geography and Computer Science. It also constitutes key reference material for Masters students working on surface analysis projects as part of a GI Science or Computer Science programme. |
