Expert perspectives on SDI theory and practice The spatial data infrastructure (SDI) concept continues to evolve and become an increasingly important element of the infrastructure that supports economic development, environmental management, and social stability. Because of its dynamic and complex nature, however, it remains a fuzzy concept

Is infrastructure but the plumbing and wiring of the human environment, or is it the true lifeblood of the spaces we inhabit? Infrastructural systems facilitate the flow of anything from people and goods to resources and information. While engineered to perform specific tasks, such networks also determine the structure of buildings, cities, and metropolitan regions, if not of entire nations and the planet itself.0Taking this critical leverage in consideration, this book calls for expanding and renegotiating the roles of infrastructure not only as a technical, but also as a political, economic, social, and even aesthetic matter of concern for all, claimed not only as the means for achieving more resilient forms of development, but moreover as a right to a sustainable way of life.0Twenty-five essays?by architects, engineers, urban theorists and policy-makers?address infrastructure as ?thing?, ?networked system? and ?agency? respectively in three chapters, which are periodically interspersed by a visual atlas of examples, that playfully celebrate infrastructure through the lens of its spatial qualities.

Spatial Infrastructure is a collection of essays crafting a self-consistent project that recasts architectural thinking as a form of knowledge by addressing a number of fundamental questions relevant to the reading of works across styles, time-periods, and geographic boundaries. José Aragüez's second book revolves around a new concept in architecture, spatial infrastructure , that operates both as a design tool capable of projecting architectural thinking forward, and as an analytical category that shifts our understanding of the history of the field and contemporary production. Taken together, the collection of essays presented here investigates some of the most intractable issues pertaining to architectural discourse, while also examining scientific, critical, and cultural dimensions where relevant. Key subjects include a building’s discursive building, engineering patents and spatial disposition in architecture, typological invention and sponge surfaces, “the organic” at the intersection of architecture and philosophy, imageability in the context of an evolving market economy, language vis-à-vis self-determinacy in creative practices, a building’s spatial kernel, and the possibility of architectural metacriticality. Building upon each other to engender a coherent and distinct outlook on twentieth-century and contemporary architecture, these essays put forth a strong argument for architectural thinking that emerges from intimate knowledge of its capacities, as well as an ability to maintain epistemological clarity and integrity when purporting to expand our horizons of understanding.

In the wake of the so-called information technology revolution, many stakeholders from the public and private sectors (including citizens) have indeed grown accustomed to the promise and usability of spatial data infrastructures (SDI) for data access, use, and sharing. Analyzing the obstacles as well as the processes and mechanisms of integration a

This book contains papers presented at the first Open Source Geospatial Research Symposium held in Nantes City, France, 8-10 July, 2009. It brings together insights and ideas in the fields of Geospatial Information and Geoinformatics. It demonstrates the scientific community dynamism related to open source and free software as well as in defining new concepts, standards or tools.

This book draws on author’s wealth of knowledge working on numerous projects across many countries. It provides a clear overview of the development of the SDI concept and SDI worldwide implementation and brings a logical chronological approach to the linkage of GIS technology with SDI enabling data. The theory and practice approach help understand that SDI development and implementation is very much a social process of learning by doing. The author masterfully selects main historical developments and updates them with an analytical perspective promoting informed and responsible use of geographic information and geospatial technologies for the benefit of society from local to global scales. Features Subject matter spans thirty years of the development of GIS and SDI. Brings a social science perspective into GIS and SDI debates that have been largely dominated by technical considerations. Based on a world-wide perspective as a result of the author's experience and research in the USA, Australia, Canada, Brazil, Peru, China, India, Korea, Malaysia, and Japan as well as most European countries. Draws upon professional and academic experience relating to pioneering UK and European GIS research initiatives. Includes updated historical material with an analytical perspective explaining what was done right, and what didn't work.

Extrastatecraft is the operating system of the modern world: the skyline of Dubai, the subterranean pipes and cables sustaining urban life, free-trade zones, the standardized dimensions of credit cards, and hyper-consumerist shopping malls. It is all this and more. Infrastructure sets the invisible rules that govern the spaces of our everyday lives, making the city the key site of power and resistance in the twenty-first century. Keller Easterling reveals the nexus of emerging governmental and corporate forces buried within the concrete and fiber-optics of our modern habitat. Extrastatecraftwill change how we think about cities-and, perhaps, how we live in them.

The National Spatial Data Infrastructure (NSDI) was envisioned as a way of enhancing the accessibility, communication, and use of geospatial data to support a wide variety of decisions at all levels of society. The goals of the NSDI are to reduce redundancy in geospatial data creation and maintenance, reduce the costs of geospatial data creation and maintenance, improve access to geospatial data, and improve the accuracy of geospatial data used by the broader community. At the core of the NSDI is the concept of partnerships, or collaborations, between different agencies, corporations, institutions, and levels of government. In a previous report, the Mapping Science Committee (MSC) defined a partnership as "...a joint activity of federal and state agencies, involving one or more agencies as joint principals focusing on geographic information." The concept of partnerships was built on the foundation of shared responsibilities, shared costs, shared benefits, and shared control. Partnerships are designed to share the costs of creation and maintenance of geospatial data, seeking to avoid unnecessary duplication, and to make it possible for data collected by one agency at a high level of spatial detail to be used by another agency in more generalized form. Over the past seven years, a series of funding programs administered by the Federal Geographic Data Committee (FGDC) has stimulated the creation of such partnerships, and thereby promoted the objectives of the NSDI, by raising awareness of the need for a coordinated national approach to geospatial data creation, maintenance, and use. They include the NSDI Cooperative Agreements Program, the Framework Demonstration Projects Program, the Community Demonstration Projects, and the Community-Federal Information Partnerships proposal. This report assesses the success of the FGDC partnership programs that have been established between the federal government and state and local government, industry, and academic communities in promoting the objectives of the National Spatial Data Infrastructure.

Metadata play a fundamental role in both DLs and SDIs. Commonly defined as "structured data about data" or "data which describe attributes of a resource" or, more simply, "information about data", it is an essential requirement for locating and evaluating available data. Therefore, this book focuses on the study of different metadata aspects, which contribute to a more efficient use of DLs and SDIs. The three main issues addressed are: the management of nested collections of resources, the interoperability between metadata schemas, and the integration of information retrieval techniques to the discovery services of geographic data catalogs (contributing in this way to avoid metadata content heterogeneity).

This book covers a range of topics including selective technologies and algorithms that can potentially contribute to developing an intelligent environment and smarter cities. While the connectivity and efficiency of smart cities is important, the analysis of the impact of construction development and large projects in the city is crucial to decision and policy makers, before the project is approved. This book also presents an agenda for future investigations to address the need for advanced tools such as mobile scanners, Geospatial Artificial Intelligence, Unmanned Aerial Vehicles, Geospatial Augmented Reality apps, Light Detection, and Ranging in smart cities. Some of selected specific tools presented in this book are as a simulator for improving the smart parking practices by modelling drivers with activity plans, a bike optimization algorithm to increase the efficiency of bike stations, an agent-based model simulation of human mobility with the use of mobile phone datasets. In addition, this book describes the use of numerical methods to match the network demand and supply of bicycles, investigate the distribution of railways using different indicators, presents a novel algorithm of direction-aware continuous moving K-nearest neighbor queries in road networks, and presents an efficient staged evacuation planning algorithm for multi-exit buildings.
