This book was released on 2013 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study is an initiative focused on establishing accurate, reliable heights using Global Navigation Satellite System (GNSS) technology in conjunction with traditional leveling, gravity, and modern remote sensing information. The traditional method for determining the elevation of these vertical benchmarks is differential leveling, but the advanced technology of Global Navigation Satellite System (GNSS) and other modern positioning technologies have begun to replace this classical technique of vertical measurement in many situations. The primary goal of this research was to contribute to the improvement of height estimation using GPS that supports the goals of the National Height Modernization project led by NGS. This was attained by investigating the required baseline length to de-correlate the tropospheric corrections at individual stations, as well as to determine the optimal network design. In order to perform these experiments, three different networks were formed: the single, the double, and the multiple base station approaches. The comparison of these three approaches concluded that the multiple base approach (combination of CORS and IGS stations) is the optimal network, which improved the estimation of the tropospheric corrections, the quality of the processing results, and the positioning accuracy, especially in the height component. This configuration reduced the possible errors associated with the base station, provides reliable tropospheric corrections and improved the accuracy of the ellipsoidal heights. These test cases also illustrated that a longer session provides higher accuracy and reliable ellipsoidal heights. Based on the results in this study, at least a two-hour data span should be used to determine the ellipsoidal heights accurately in OPUS-Projects. Additionally, a second independent observation should be used to increase the confidence in the processing results. In order to maximize independence of the observations, the second observation should be obtained on a different day and at a different time of day. This project is closely related to project 134692, Impact of Lakeside Subsidence on Benchmark Reliability.

Download or read book Elevation Data for Floodplain Mapping written by National Research Council and published by National Academies Press. This book was released on 2007-09-16 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Floodplain maps serve as the basis for determining whether homes or buildings require flood insurance under the National Flood Insurance Program run by the Federal Emergency Management Agency (FEMA). Approximately $650 billion in insured assets are now covered under the program. FEMA is modernizing floodplain maps to better serve the program. However, concerns have been raised as to the adequacy of the base map information available to support floodplain map modernization. Elevation Data for Floodplain Mapping shows that there is sufficient two-dimensional base map imagery to meet FEMA's flood map modernization goals, but that the three-dimensional base elevation data that are needed to determine whether a building should have flood insurance are not adequate. This book makes recommendations for a new national digital elevation data collection program to redress the inadequacy. Policy makers; property insurance professionals; federal, local, and state governments; and others concerned with natural disaster prevention and preparedness will find this book of interest.
