Download or read book Design, Implementation, and Integration of Data Types for Three-dimensional Spatial Data in Databases written by Tao Chen and published by . This book was released on 2012 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spatial database systems so far have dealt mostly with two-dimensional spatial entities, and the support for three-dimensional data management has been largely neglected. The primary goal of the proposed research is to develop a new formal data model and type system called Spatial Algebra 3D (SPAL3D) for three-dimensional (3D) spatial data in database systems. In this research, we explore the fundamental properties and the structure of complex 3D spatial data from a data management and database perspective, identifies and designs algorithms for their most important operations and predicates, and supports their representation and storage in database systems.
Book Synopsis A Formal Design for Three-Dimensional Spatial Data in Database Systems by : Brian E. Weinrich
Download or read book A Formal Design for Three-Dimensional Spatial Data in Database Systems written by Brian E. Weinrich and published by LAP Lambert Academic Publishing. This book was released on 2010-03 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous work with spatial database systems has dealt mostly with two dimensions and more with implementation than with design issues. This dissertation deals with the formal design of three- dimensional spatial database systems and with the need for abstraction in the design. Use of abstraction in the formal design of data models allows a database system developer to consider the comprehensive needs of users at an ideal level unencumbered by implementation details. The dissertation also presents a set of robust three- dimensional geometric primitives that could form the core of a discrete data model. Although a discrete data model is more concrete than SPAL3D, it has some abstraction. The dissertation offers a precise and conceptually clean specification and foundation for implementing a Database Management System (DBMS) extension for three-dimensional data. Assuming the existence of an implementation of this type system, it demonstrates the embedding of the spatial data types as attribute data types in database schemas as well as the incorporation of the operations and predicates into queries formulated in a possible extension of SQL.

Book Synopsis The 3-D Global Spatial Data Model by : Earl F. Burkholder
Download or read book The 3-D Global Spatial Data Model written by Earl F. Burkholder and published by CRC Press. This book was released on 2008-04-15 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditional methods for handling spatial data are encumbered by the assumption of separate origins for horizontal and vertical measurements. Modern measurement systems operate in a 3-D spatial environment. The 3-D Global Spatial Data Model: Foundation of the Spatial Data Infrastructure offers a new model for handling digital spatial data, the global spatial data model or GSDM. The GSDM preserves the integrity of three-dimensional spatial data while also providing additional benefits such as simpler equations, worldwide standardization, and the ability to track spatial data accuracy with greater specificity and convenience. This groundbreaking spatial model incorporates both a functional model and a stochastic model to connect the physical world to the ECEF rectangular system. Combining horizontal and vertical data into a single, three-dimensional database, this authoritative monograph provides a logical development of theoretical concepts and practical tools that can be used to handle spatial data more efficiently. The book clearly describes procedures that can be used to handle both ECEF and flat-Earth rectangular components in the context of a rigorous global environment.

Book Synopsis Large-scale 3d Data Integration by : Sisi Zlatanova
Download or read book Large-scale 3d Data Integration written by Sisi Zlatanova and published by CRC Press. This book was released on 2019-12-02 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large-Scale 3D Data Integration: Challenges and Opportunities examines the fundamental aspects of 3D geo-information, focusing on the latest developments in 3D GIS (geographic information) and AEC (architecture, engineering, construction) systems. This book addresses policy makers, designers and engineers, and individuals that need to overcome obstacles in integrating modeling perspectives and data. Organized into four major parts, the book begins by presenting a historical overview of the issues involved in integrating GIS and AEC. Part II then focuses on the data issue from several viewpoints: data collection; database structures and representation; database management; and visualization. Part III covers the areas of semantics, ontology, and standardization from a theoretical perspective and details many of the best examples of this approach in developing real-world applications. The book concludes with contributions that focus on recent advances in virtual geographic environments and alternative modeling schemes for the potential AEC/GIS interface.
Book Synopsis Design, Implementation, and Database Integration of a Data Model for Vague Spatial Data as a Foundation of the Next Generation of Spatial Databases and Geographical Information Systems by : Alejandro Pauly

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We also provide the details of the mSLOB mechanism for handling multi-structured large objects in databases. The mechanism currently works as the generic interface between SPAL2D and any DBMS for which mSLOB can be implemented. My dissertation offers a precise and conceptually clean foundation for implementing a DBMS extension for vague spatial data and demonstrates the embedding of these new data types as attribute data types in a database schema as well as the incorporation of vague spatial operations and predicates into queries formulated in an SQL-like query language.
Book Synopsis The Design and Implementation of Two-dimentional Spatial Data Types and Their Integration Into a Relational Database Management System by : Pierre Akiki

This book was released on 2007 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term spatial data signifies all geometric objects of different dimensions and the relations that could bind these objects together. Spatial data is, in general, divided into two parts: crisp spatial data and vague spatial data. Crisp spatial data has determinate coordinates and boundaries, whereas vague spatial data has indeteminate ones. The demand for spatial data support in database management systems is growing every day, yet not all commercial products provide spatial data support natively, and those that do merely provide it partially. Since database management systems are at the heart of most data-oriented applications, generic support for non--traditional data types (such as spatial data types) is required from such systems. The main goal of this thesis is to analyze spatial data in detail and to propose a method for storing and manipulating such data. Both crisp and vague spatial data were analyzed, and their usage and major aspects were highlighted. We also studied existing support for spartial data in commercial database management systems and pointed out the existing lack of functionality in those systems. We propose several ways of storing crisp spatial data based on some Open GIS Consortium (OGC) standards and on manipulating it by means of computational geometry. We also propose ways to represent and manipulate vague spatial data. These propositions were based on sampling techniques, which are used in the filed on GIS. In order to prove our concepts, we designed and implemented a spatial extension package (SPEX) and integrated it in a commercial relational database management system. We also devised the necessary visual components and a software prototype to test our package. We conclude our thesis by enforcing the idea of the "common object store," which is a DBMS capable of storing and manipulating all sorts of data (relational data, objects, multimedia, spatial, etc.).

This book was released on 2009-10-16 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Realistically representing our three-dimensional world has been the subject of many (philosophical) discussions since ancient times. While the recognition of the globular shape of the Earth goes back to Pythagoras’ statements of the sixth century B. C. , the two-dimensional, circular depiction of the Earth’s surface has remained prevailing and also dominated the art of painting until the late Middle Ages. Given the immature technological means, objects on the Earth’s surface were often represented in academic and technical disciplines by two-dimensional cross-sections oriented along combinations of three mutually perpendicular directions. As soon as computer science evolved, scientists have steadily been improving the three-dimensional representation of the Earth and developed techniques to analyze the many natural processes and phenomena taking part on its surface. Both computer aided design (CAD) and geographical information systems (GIS) have been developed in parallel during the last three decades. While the former concentrates more on the detailed design of geometric models of object shapes, the latter emphasizes the topological relationships between geographical objects and analysis of spatial patterns. Nonetheless, this distinction has become increasingly blurred and both approaches have been integrated into commercial software packages. In recent years, an active line of inquiry has emerged along the junctures of CAD and GIS, viz. 3D geoinformation science. Studies along this line have recently made significant inroads in terms of 3D modeling and data acquisition.
