Available in PDF, EPUB and Kindle. Book excerpt: Analyzing and mining various kinds of geo-referenced data is important in many application areas. We use two types of data: geo-referenced trajectories, such as vehicular tracking data, as well as geo-referenced graph data, such as street maps. This dissertation consists of two main parts. In the first part, we consider the problem of constructing street maps from geo-referenced trajectories: Given a set of trajectories in the plane, compute a street-map that represents all trajectories in the set. In this part, we have two main contributions. First, we present a scalable incremental algorithm that is based on partial matching of the trajectories to the graph. For the partial matching we introduce a new variant of partial Fréchet distance. We use minimum-link paths to reduce the complexity of the generated map. We provide quality guarantees and experimental results based on both real and synthetic data. We further present two multi-thresholding techniques for density-based map construction algorithms. Multi-thresholding is necessary because some streets are travelled more heavily than other streets (highways vs. neighborhood streets), which results in different sampling densities, and thus, one threshold fails to capture all the streets. We present a new thresholding technique that uses persistent homology combined with statistical analysis to determine a small set of thresholds that captures all or most of the significant topological features. We also formalize the selection of thresholds in a density-based map construction algorithm for different variants of uniform sampling. In part two of the dissertation, we consider the map comparison problem: Given two street-maps embedded in space, quantify their differences. Given maps of the same city collected from different sources, researchers often need to know how they differ. Map comparison is very important in the field of transportation network analysis as well as to assess the quality of map construction algorithms. We present a new path-based distance measure to compare two planar geometric graphs that are embedded in the same plane. Our distance measure takes structural as well as spatial properties into account. We show that it can be approximated in polynomial time and it preserves structural and spatial properties of the graphs. We provide experimental results comparing vendor quality street maps (TeleAtlas) with open source maps (OpenStreetMap), as well as maps generated by map construction algorithms with ground-truth maps (OpenStreetMap).

Available in PDF, EPUB and Kindle. Book excerpt: The book provides an overview of the state-of-the-art of map construction algorithms, which use tracking data in the form of trajectories to generate vector maps. The most common trajectory type is GPS-based trajectories. It introduces three emerging algorithmic categories, outlines their general algorithmic ideas, and discusses three representative algorithms in greater detail. To quantify map construction algorithms, the authors include specific datasets and evaluation measures. The datasets, source code of map construction algorithms and evaluation measures are publicly available on http://www.mapconstruction.org. The web site serves as a repository for map construction data and algorithms and researchers can contribute by uploading their own code and benchmark data. Map Construction Algorithms is an excellent resource for professionals working in computational geometry, spatial databases, and GIS. Advanced-level students studying computer science, geography and mathematics will also find this book a useful tool.

Download or read book Handbook of Discrete and Computational Geometry written by Csaba D. Toth and published by CRC Press. This book was released on 2017-11-22 with total page 1928 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Discrete and Computational Geometry is intended as a reference book fully accessible to nonspecialists as well as specialists, covering all major aspects of both fields. The book offers the most important results and methods in discrete and computational geometry to those who use them in their work, both in the academic world—as researchers in mathematics and computer science—and in the professional world—as practitioners in fields as diverse as operations research, molecular biology, and robotics. Discrete geometry has contributed significantly to the growth of discrete mathematics in recent years. This has been fueled partly by the advent of powerful computers and by the recent explosion of activity in the relatively young field of computational geometry. This synthesis between discrete and computational geometry lies at the heart of this Handbook. A growing list of application fields includes combinatorial optimization, computer-aided design, computer graphics, crystallography, data analysis, error-correcting codes, geographic information systems, motion planning, operations research, pattern recognition, robotics, solid modeling, and tomography.

Available in PDF, EPUB and Kindle. Book excerpt: Mobile Mapping technologies have seen a rapid growth of research activity and interest in the last years, due to the increased demand of accurate, dense and geo-referenced 3D data. Their main characteristic is the ability of acquiring 3D information of large areas dynamically. This versatility has expanded their application fields from the civil engineering to a broader range (industry, emergency response, cultural heritage...), which is constantly widening. This increased number of needs, some of them specially challenging, is pushing the Scientific Community, as well as companies, towards the development of innovative solutions, ranging from new hardware / open source software approaches and integration with other devices, up to the adoption of artificial intelligence methods for the automatic extraction of salient features and quality assessment for performance verification The aim of the present book is to cover the most relevant topics and trends in Mobile Mapping Technology, and also to introduce the new tendencies of this new paradigm of geospatial science.
