A new perspective on topographic map formation and the advantages of information-based learning The study of topographic map formation provides us with important tools for both biological modeling and statistical data modeling. Faithful Representations and Topographic Maps offers a unified, systematic survey of this rapidly evolving field, focusing on current knowledge and available techniques for topographic map formation. The author presents a cutting-edge, information-based learning strategy for developing equiprobabilistic topographic maps--that is, maps in which all neurons have an equal probability to be active--clearly demonstrating how this approach yields faithful representations and how it can be successfully applied in such areas as density estimation, regression, clustering, and feature extraction. The book begins with the standard approach of distortion-based learning, discussing the commonly used Self-Organizing Map (SOM) algorithm and other algorithms, and pointing out their inadequacy for developing equiprobabilistic maps. It then examines the advantages of information-based learning techniques, and finally introduces a new algorithm for equiprobabilistic topographic map formation using neurons with kernel-based response characteristics. The complete learning algorithms and simulation details are given throughout, along with comparative performance analysis tables and extensive references. Faithful Representations and Topographic Maps is an excellent, eye-opening guide for neural network researchers, industrial scientists involved in data mining, and anyone interested in self-organization and topographic maps.

Explains how to read and understand a topographic map.

Audisee® eBooks with Audio combine professional narration and text highlighting for an engaging read aloud experience! Want to know just how tall Mount Everest is? Or what the city of Denver's elevation is? Then look at a topographic map! These maps use lines to show the height and shape of Earth's surface. But how do you read the lines? And what other features do these maps have? Read on to learn the ins and outs of topographic maps!

Which trail has a gentle slope? Where are the highest mountains along the Appalachian Trail? Is there a lake along the route? As students read this engaging volume, they will learn how to use United States Geological Survey (USGS) contour maps to answer these questions. They'll get an historical overview of how surveyors used to create these maps, and how technology now helps create more accurate maps. Students will construct 3D models of areas on a topographic map.

The “utterly fascinating” untold story of Soviet Russia’s global military mapping program—featuring many of the surprising maps that resulted (Marina Lewycka, author of A Short History of Tractors in Ukrainian). From 1950 to 1990, the Soviet Army conducted a global topographic mapping program, creating large-scale maps for much of the world that included a diversity of detail that would have supported a full range of military planning. For big cities like New York, Washington, D.C., and London to towns like Pontiac, MI, and Galveston, TX, the Soviets gathered enough information to create street-level maps. The information on these maps ranged from the locations of factories and ports to building heights, road widths, and bridge capacities. Some of the detail suggests early satellite technology, while other specifics, like detailed depictions of depths and channels around rivers and harbors, could only have been gained by Soviet spies on the ground. The Red Atlas includes over 350 extracts from these incredible Cold War maps, exploring their provenance and cartographic techniques as well as what they can tell us about their makers and the Soviet initiatives that were going on all around us.
