Download or read book Designing Querying Implementing and Integrating Spatial Networks in Spatial Databases written by Virupaksha Kanjilal and published by . This book was released on 2012 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spatial networks like road networks, pipeline networks, transportation networks, and power network are being increasingly used in the fields of route planning, land use planning, city planning, traffic forecasting thus promising the generation of vast amounts of spatial networks data. While in order to efficiently handle, represent, store, query, and manipulate large spatial networks database support is a must, database support for spatial networks is rare. Our project aims to provide a conceptual, abstract, and formal model of spatial networks, called Spatial Network Algebra (SNA), that includes types, operations, and predicates and can serve as a specification for their later implementation in spatial database systems and GIS. Based on this abstract model of spatial networks, we will create an implementation of a spatial network data type which we will incorporate in a spatial database. In the context of spatial databases retrieval and handling of spatial networks through querying becomes critical to exploiting the functionality of database. Thus query mechanisms which are able to handle the complexity of spatial networks data becomes essential. Consequently, we show how our spatial network concepts can be embedded into an SQL-like query language.

Available in PDF, EPUB and Kindle. Book excerpt: Spatial database management deals with the storage, indexing, and querying of data with spatial features, such as location and geometric extent. Many applications require the efficient management of spatial data, including Geographic Information Systems, Computer Aided Design, and Location Based Services. The goal of this book is to provide the reader with an overview of spatial data management technology, with an emphasis on indexing and search techniques. It first introduces spatial data models and queries and discusses the main issues of extending a database system to support spatial data. It presents indexing approaches for spatial data, with a focus on the R-tree. Query evaluation and optimization techniques for the most popular spatial query types (selections, nearest neighbor search, and spatial joins) are portrayed for data in Euclidean spaces and spatial networks. The book concludes by demonstrating the ample application of spatial data management technology on a wide range of related application domains: management of spatio-temporal data and high-dimensional feature vectors, multi-criteria ranking, data mining and OLAP, privacy-preserving data publishing, and spatial keyword search.

Available in PDF, EPUB and Kindle. Book excerpt: This handbook covers a wide range of topics related to the collection, processing, analysis, and use of geospatial data in their various forms. This handbook provides an overview of how spatial computing technologies for big data can be organized and implemented to solve real-world problems. Diverse subdomains ranging from indoor mapping and navigation over trajectory computing to earth observation from space, are also present in this handbook. It combines fundamental contributions focusing on spatio-textual analysis, uncertain databases, and spatial statistics with application examples such as road network detection or colocation detection using GPUs. In summary, this handbook gives an essential introduction and overview of the rich field of spatial information science and big geospatial data. It introduces three different perspectives, which together define the field of big geospatial data: a societal, governmental, and governance perspective. It discusses questions of how the acquisition, distribution and exploitation of big geospatial data must be organized both on the scale of companies and countries. A second perspective is a theory-oriented set of contributions on arbitrary spatial data with contributions introducing into the exciting field of spatial statistics or into uncertain databases. A third perspective is taking a very practical perspective to big geospatial data, ranging from chapters that describe how big geospatial data infrastructures can be implemented and how specific applications can be implemented on top of big geospatial data. This would include for example, research in historic map data, road network extraction, damage estimation from remote sensing imagery, or the analysis of spatio-textual collections and social media. This multi-disciplinary approach makes the book unique. This handbook can be used as a reference for undergraduate students, graduate students and researchers focused on big geospatial data. Professionals can use this book, as well as practitioners facing big collections of geospatial data.

Download or read book Spatial Database for GPS Wildlife Tracking Data written by Ferdinando Urbano and published by Springer Science & Business Media. This book was released on 2014-03-12 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book guides animal ecologists, biologists and wildlife and data managers through a step-by-step procedure to build their own advanced software platforms to manage and process wildlife tracking data. This unique, problem-solving-oriented guide focuses on how to extract the most from GPS animal tracking data, while preventing error propagation and optimizing analysis performance. Based on the open source PostgreSQL/PostGIS spatial database, the software platform will allow researchers and managers to integrate and harmonize GPS tracking data together with animal characteristics, environmental data sets, including remote sensing image time series, and other bio-logged data, such as acceleration data. Moreover, the book shows how the powerful R statistical environment can be integrated into the software platform, either connecting the database with R, or embedding the same tools in the database through the PostgreSQL extension Pl/R. The client/server architecture allows users to remotely connect a number of software applications that can be used as a database front end, including GIS software and WebGIS. Each chapter offers a real-world data management and processing problem that is discussed in its biological context; solutions are proposed and exemplified through ad hoc SQL code, progressively exploring the potential of spatial database functions applied to the respective wildlife tracking case. Finally, wildlife tracking management issues are discussed in the increasingly widespread framework of collaborative science and data sharing. GPS animal telemetry data from a real study, freely available online, are used to demonstrate the proposed examples. This book is also suitable for undergraduate and graduate students, if accompanied by the basics of databases.

Download or read book Parallel and In memory Big Spatial Data Processing Systems and Benchmarking written by Md. Mahbub Alam and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the accelerated growth in spatial data volume, being generated from a wide variety of sources, the need for efficient storage, retrieval, processing and analyzing of spatial data is ever more important. Hence, the spatial data processing system has become an important field of research. Though the traditional relational database systems provide spatial functionality (such as, PostgreSQL with PostGIS), due to the lack of parallelism and I/O bottleneck, these systems are not efficient to run compute-intensive spatial queries on large datasets. In recent times a number of big spatial data systems have been proposed by researchers around the world. These systems can be roughly categorized into disk-based systems over Apache Hadoop and in memory systems based on Apache Spark. The available features supported by these systems vary widely. However, there has not been any comprehensive evaluation study of these systems in terms of performance, scalability, and functionality. In order to address this need, this thesis proposes a benchmark to evaluate big spatial data systems. It intends to investigate the present status of the big spatial data systems by conducting a comprehensive feature analysis and performance evaluation of a few representative systems. The Hadoop and Spark based big spatial data systems are distributed, scalable, and able to exploit the parallelism of today’s multi-core/many-core architecture. However, most of them are immature, unstable, difficult to extend and missing efficient query language like SQL. In this work, a disk based system Parallax is introduced as a parallel big spatial database system. It integrates the powerful spatial features of PostgreSQL/PostGIS and distributed persistence storage of Alluxio. The host-specific data partitioning and parallel query on local data in each node ensure the maximum utilization of main memory, disk storage, and CPU. This thesis also introduces an in-memory system SpatialIgnite, as extended spatial support for Apache Ignite. SpatialIgnite incorporates a spatial library which contains all the OGC compliant join predicates and spatial analysis functions. Along with query parallelism and collocated query processing of Ignite, the integrated spatial data partitioning techniques improve the performance of SpatialIgnite. The evaluation shows that Spatial Ignite performs better than Hadoop and Spark based systems.
