Book excerpt: The objective of this research is to determine the possibility of an alternative for government-developed satellites which produce high resolution imagery. This study focuses on the concept of the U.S. government purchasing proven and successful commercial satellites with minimal non-recurring engineering costs to help augment current national systems. The benefit with this alternative is the reliability and affordability of a system that is currently used in space and therefore reduces a significant amount of risk as well as production time. A constellation of commercial satellites that are reconstituted on a monthly or quarterly cycle could also invigorate the commercial satellite work force and better produce future systems. A disadvantage with an architecture of commercial satellites are potential limitations with geolocation accuracy and data rate downlink transmission capability. This thesis evaluates constellation design factors such as orbit types, number of satellites, life-cycle and ground segment implementation. A coverage capability evaluation is provided to determine how a commercial system would be able to fulfill national imagery collection requirements. Eight different constellation types were created, ranging from one to 12 satellites in size. Orbit analysis settled on a sun-synchronous polar elliptical orbit at 185 km x 700 km, using an existing commercial satellite with a 0.6m optic. This provided imaging with a resolution range between 10-37 inches. The largest constellation of 12 satellites would provide a daily area collection of 43,000 km2 and 150 point images for a region the size of Iraq and would have an estimated $1-2B cost for an annual life cycle cost. Revisit time for mid-latitude targets was approximately one day at 10 inch resolution.

Download or read book U S Commercial Remote Sensing Satellite Industry written by Kevin M. O'Connell and published by Minnesota Historical Society. This book was released on 2001 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: American firms have begun to operate their own imaging satellite systems, aiming to become an important part of the U.S. commercial remote sensing industry. To succeed over the long run, these new U.S. commercial remote sensing satellite firms need a combination of reliable technologies, government policies that encourage U.S. industry competitiveness, a strong international presence, and sound business plans to ensure their competitiveness in both the domestic and international marketplaces. The greatest risks for the these firms come from the challenge of transforming themselves from imagery data providers to strong competitors as information age companies; the need to master the technical risks of building and operating sophisticated imaging satellite systems; and the requirement to operate effectively in a complex international business environment. In addition, the government_s policymaking process has yet to achieve the degree of predictability, timeliness, and transparency that the firms need if they are expected to operate effectively in a highly competitive and rapidly changing global marketplace. The authors conclude with six recommendations that the U.S. Department of Commerce should adopt to best fulfill its responsibilities for promoting the U.S. commercial remote sensing industry and for encouraging the competitiveness of new private imaging satellite firms.
Download or read book The Image of the City written by Kevin Lynch and published by MIT Press. This book was released on 1964-06-15 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: The classic work on the evaluation of city form. What does the city's form actually mean to the people who live there? What can the city planner do to make the city's image more vivid and memorable to the city dweller? To answer these questions, Mr. Lynch, supported by studies of Los Angeles, Boston, and Jersey City, formulates a new criterion—imageability—and shows its potential value as a guide for the building and rebuilding of cities. The wide scope of this study leads to an original and vital method for the evaluation of city form. The architect, the planner, and certainly the city dweller will all want to read this book.

Download or read book Comparison of GIS based and High Resolution Satellite Imagery Population Modeling written by Julia Kubanek and published by BoD – Books on Demand. This book was released on 2011-10-01 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decades, the rapid growth of the world population has led to a large number of emerging megacities. The 1999 Izmit (Turkey) earthquake is a striking example of the impact of natural hazards on megacities. On August 17, 1999, a magnitude 7.6 earthquake struck the area of Izmit, Turkey, resulting in 18,000 fatalities and US$ 18 billion in economic losses. The probability of a magnitude 7 earthquake striking Istanbul within the next 30 years ranges between 30% to 70%. In order to reduce the impact of natural hazards on human lives, emergency management plans are essential. The development of these plans strongly relies on up-to-date population and inventory data. However, existing techniques for population data generation do not meet the requirements of today’s dynamic cities. In this context, remote sensing has become an important source of information in the last years. However, detailed analyses on the suitability of remote sensing for urban applications are still rare.For her study, Julia Kubanek conducted a quantitative evaluation of the suitability of Ikonos imagery (1m resolution) for population modeling in the district of Zeytinburnu (Istanbul, Turkey). The results show that Ikonos images can be used for complementing existing inventory data sets. The automated extraction of single buildings was identified as the major source of error in the estimation of the population. Kubanek's study discusses the replacement of traditional, time-consuming and cost-intensive techniques for population estimation with remotely sensed imagery as a relatively new data source in an increasingly urbanized and fast-changing world. Her book addresses scientists and professionals in geography, remote sensing, urban planning, and natural hazards research.

Download or read book The Potential Uses of Commercial Satellite Imagery in the Middle East written by and published by . This book was released on 1999 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: It became clear during the workshop that the applicability of commercial satellite imagery to the verification of future regional arms control agreements is limited at this time. Non-traditional security topics such as environmental protection, natural resource management, and the development of infrastructure offer the more promising applications for commercial satellite imagery in the short-term. Many problems and opportunities in these topics are regional, or at least multilateral, in nature. A further advantage is that, unlike arms control and nonproliferation applications, cooperative use of imagery in these topics can be done independently of the formal Middle East Peace Process. The value of commercial satellite imagery to regional arms control and nonproliferation, however, will increase during the next three years as new, more capable satellite systems are launched. Aerial imagery, such as that used in the Open Skies Treaty, can also make significant contributions to both traditional and non-traditional security applications but has the disadvantage of requiring access to national airspace and potentially higher cost. There was general consensus that commercial satellite imagery is under-utilized in the Middle East and resources for remote sensing, both human and institutional, are limited. This relative scarcity, however, provides a natural motivation for collaboration in non-traditional security topics. Collaborations between scientists, businesses, universities, and non-governmental organizations can work at the grass-roots level and yield contributions to confidence building as well as scientific and economic results. Joint analysis projects would benefit the region as well as establish precedents for cooperation.

Download or read book Forms of Aid written by Benedict Clouette and published by Birkhäuser. This book was released on 2017-09-11 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: For some time now, the subject of cooperation in the context of development aid has featured in the education of architects. However, up to now there have hardly been any attempts to critically place the work of architects and urban designers in this context. The book highlights the architectural consequences of humanitarian actions on the basis of three case studies – in Port-au-Prince, the West Bank, and Nairobi. The authors analyze twelve projects in terms of typology and construction and establish a differentiated position in the discourse on short-term housing for emergency situations. They investigate the far-reaching effects of such architectural aid and supply architects, town planners, and NGOs with useful advice for future planning and design.
Download or read book Licensing Geographic Data and Services written by National Research Council and published by National Academies Press. This book was released on 2004-11-13 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geographic data are used in all sectors of society to support a huge range of applications ranging from emergency response to land-use planning to location-based services. In the past, government agencies typically acquired ownership of such data from private-sector and other data producers and distributed these data without restriction. Licensing-whereby the producer may restrict redistribution-has emerged as an alternative business model that agencies must now consider among a suite of procurement options. The report highlights licensing perspectives and experiences of major stakeholder groups and examines the pros and cons of licensing. It concludes that licensing may be a viable option in some instances and advises agencies on how to best serve societal interests.

Download or read book Visioning Technologies written by Graham Cairns and published by Routledge. This book was released on 2016-12-08 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visioning Technologies brings together a collection of texts from leading theorists to examine how architecture has been, and is, reframed and restructured by the visual and theoretical frameworks introduced by different ‘technologies of sight’ – understood to include orthographic projection, perspective drawing, telescopic devices, photography, film and computer visualization, amongst others. Each chapter deals with its own area and historical period of expertise, organized sequentially to mark out and analyse the historical evolution of how architecture has been transformed by technologically induced shifts in human perception from the 15th century until today. This book underlines the way in which architectural forms and design processes have developed historically in conjunction with the systems of sight we manufacture technologically and suggests this continues today. Paradoxically, it is premised on the argument that these technological systems tend, in their initial formulations, to obtain ever greater realism in our visualizations of the physical world.

Download or read book Close Up at a Distance written by Laura Kurgan and published by MIT Press. This book was released on 2013-03-26 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maps poised at the intersection of art, architecture, activism, and geography trace a profound shift in our understanding and experience of space. The maps in this book are drawn with satellites, assembled with pixels radioed from outer space, and constructed from statistics; they record situations of intense conflict and express fundamental transformations in our ways of seeing and of experiencing space. These maps are built with Global Positioning Systems (GPS), remote sensing satellites, or Geographic Information Systems (GIS): digital spatial hardware and software designed for such military and governmental uses as reconnaissance, secrecy, monitoring, ballistics, the census, and national security. Rather than shying away from the politics and complexities of their intended uses, in Close Up at a Distance Laura Kurgan attempts to illuminate them. Poised at the intersection of art, architecture, activism, and geography, her analysis uncovers the implicit biases of the new views, the means of recording information they present, and the new spaces they have opened up. Her presentation of these maps reclaims, repurposes, and discovers new and even inadvertent uses for them, including documentary, memorial, preservation, interpretation, political, or simply aesthetic. GPS has been available to both civilians and the military since 1991; the World Wide Web democratized the distribution of data in 1992; Google Earth has captured global bird's-eye views since 2005. Technology has brought about a revolutionary shift in our ability to navigate, inhabit, and define the spatial realm. The traces of interactions, both physical and virtual, charted by the maps in Close Up at a Distance define this shift.
