Book Synopsis Geo-referenced Digital Data Acquisition and Processing System Using LiDAR Technology by : Charles K. Toth
Download or read book Geo-referenced Digital Data Acquisition and Processing System Using LiDAR Technology written by Charles K. Toth and published by . This book was released on 2006 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: LiDAR technology, introduced in the late 90s, has received wide acceptance in airborne surveying as a leading tool for obtaining high-quality surface data at decimeter-level vertical accuracy in an unprecedentedly short turnaround time. State-of-the-art LiDAR systems can easily achieve 2-3 cm ranging accuracy, which is certainly the accuracy range required by engineering-scale mapping. However, this is also the accuracy range that cannot be realized by routine navigation-based direct sensor platform orientation. The main objective of the project was to achieve this accuracy as closely as possible and then introduce it into the daily operation of ODOT Office of Aerial Engineering. Several tests confirmed that by using LiDAR specific ground targets, engineering-scale mapping accuracy can be achieved in normal production. The final report presents surface modeling studies, sensor calibration developments, the concept and design of LiDAR specific ground targets; followed by performance validation results, based on test flights performed by the OAE staff and preliminary investigation of image fusion with LiDAR data.

Download or read book Guide for Efficient Geospatial Data Acquisition Using LiDAR Surveying Technology written by and published by . This book was released on 2016 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: State transportation agencies (STAs) rely on implementing innovative new processes and technology for managing roadway assets; LiDAR surveys are one of these key enabling technologies. LiDAR surveys comprise an ever-evolving set of technologies that allow for a rapid, yet very accurate, collection of roadway asset data through a single effort which, when specified, integrated, and used correctly, can result in efficient workflows for agencies. While STAs may already be collecting data for specific purposes, these efforts are often duplicated within various agency disciplines using a variety of collection methods and standards. LiDAR surveys help consolidate resources, thus maximizing funding and enhancing the accuracy and integration of information. While the process for implementing LiDAR surveys will depend on a number of factors — most notably the agency’s current pre-construction, post-construction, asset inventory practices, process maturity, internal technical resources, and available funding — this guide draws the decision makers’ attention to the key issues that must be addressed for the optimization of data collection for use in an enterprise digital data solution. These include developing information requirements for data collection and products to be delivered for specific purposes and disciplines within the agency, and implementing the data collection program itself.

Available in PDF, EPUB and Kindle. Book excerpt: The report describes the design and operation of a data-acquisition system which uses digital circuits and an on-line PDP-8/I computer for real-time data processing to make upper atmospheric LIDAR measurements. The system is presently being used with the high-power pulsed ruby laser which has recently been installed at the Mount Haleakala Observatory, Maui, Hawaii. The report discusses the basic concepts involved in obtaining LIDAR measurements of atmospheric backscattering. Expected signal returns for both the 'current' (lower atmosphere) and pulse-counting (upper atmosphere) cases are calculated. Noise and background sources are considered in detail, and the statistical nature of the upper atmospheric experiments is emphasized. Detailed circuit diagrams for the data acquisition system and a LIDAR data-acquisition program for the PDP-8/I computer are also included. Preliminary data obtained with the LIDAR system is presented and compared with prediction.

Book Synopsis Accuracy Assessment of LiDAR Point Cloud Geo-referencing by : Keith E. Williams
Download or read book Accuracy Assessment of LiDAR Point Cloud Geo-referencing written by Keith E. Williams and published by . This book was released on 2012 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three-dimensional laser scanning has revolutionized spatial data acquisition and can be completed from a variety of platforms including airborne (ALS), mobile (MLS), and static terrestrial (TLS) laser scanning. MLS is a rapidly evolving technology that provides increases in efficiency and safety over static TLS, while still providing similar levels of accuracy and resolution. The componentry that make up a MLS system are more parallel to Airborne Laser Scanning (ALS) than to that of TLS. However, achievable accuracies, precisions, and resolution results are not clearly defined for MLS systems. As such, industry professionals need guidelines to standardize the process of data collection, processing, and reporting. This thesis lays the foundation for MLS guidelines with a thorough review of currently available literature that has been completed in order to demonstrate the capabilities and limitations of a generic MLS system. A key difference between MLS and TLS is that a mobile platform is able to collect a continuous path of geo-referenced points along the navigation path, while a TLS collects points from many separate reference frames as the scanner is moved from location to location. Each individual TLS setup must be registered (linked with a common coordinate system) to adjoining scan setups. A study was completed comparing common methods of TLS registration and geo-referencing (e.g., target, cloud-cloud, and hybrid methods) to assist a TLS surveyor in deciding the most appropriate method for their projects. Results provide insight into the level of accuracy (mm to cm level) that can be achieved using the various methods as well as the field collection and office processing time required to obtain a fully geo-referenced point cloud. Lastly, a quality assurance methodology has been developed for any form of LiDAR data to verify both the absolute and relative accuracy of a point cloud without the use of retro-reflective targets. This methodology incorporates total station validation of a scanners point cloud to compare slopes of common features. The comparison of 2D slope features across a complex geometry of cross-sections provides 3D positional error in both horizontal and vertical component. This methodology lowers the uncertainty of single point accuracy statistics for point clouds by utilizing a larger portion of a point cloud for statistical accuracy verification. This use of physical features for accuracy validation is particularly important for MLS systems because MLS systems cannot produce sufficient resolution on targets for accuracy validation unless they are placed close to the vehicle.

Download or read book Treatise on Geomorphology written by and published by Academic Press. This book was released on 2013-02-27 with total page 6392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The changing focus and approach of geomorphic research suggests that the time is opportune for a summary of the state of discipline. The number of peer-reviewed papers published in geomorphic journals has grown steadily for more than two decades and, more importantly, the diversity of authors with respect to geographic location and disciplinary background (geography, geology, ecology, civil engineering, computer science, geographic information science, and others) has expanded dramatically. As more good minds are drawn to geomorphology, and the breadth of the peer-reviewed literature grows, an effective summary of contemporary geomorphic knowledge becomes increasingly difficult. The fourteen volumes of this Treatise on Geomorphology will provide an important reference for users from undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic. Information on the historical development of diverse topics within geomorphology provides context for ongoing research; discussion of research strategies, equipment, and field methods, laboratory experiments, and numerical simulations reflect the multiple approaches to understanding Earth’s surfaces; and summaries of outstanding research questions highlight future challenges and suggest productive new avenues for research. Our future ability to adapt to geomorphic changes in the critical zone very much hinges upon how well landform scientists comprehend the dynamics of Earth’s diverse surfaces. This Treatise on Geomorphology provides a useful synthesis of the state of the discipline, as well as highlighting productive research directions, that Educators and students/researchers will find useful. Geomorphology has advanced greatly in the last 10 years to become a very interdisciplinary field. Undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic will find the answers they need in this broad reference work which has been designed and written to accommodate their diverse backgrounds and levels of understanding Editor-in-Chief, Prof. J. F. Shroder of the University of Nebraska at Omaha, is past president of the QG&G section of the Geological Society of America and present Trustee of the GSA Foundation, while being well respected in the geomorphology research community and having won numerous awards in the field.

Book Synopsis Coral Reef Remote Sensing by : James A. Goodman
Download or read book Coral Reef Remote Sensing written by James A. Goodman and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remote sensing stands as the defining technology in our ability to monitor coral reefs, as well as their biophysical properties and associated processes, at regional to global scales. With overwhelming evidence that much of Earth’s reefs are in decline, our need for large-scale, repeatable assessments of reefs has never been so great. Fortunately, the last two decades have seen a rapid expansion in the ability for remote sensing to map and monitor the coral reef ecosystem, its overlying water column, and surrounding environment. Remote sensing is now a fundamental tool for the mapping, monitoring and management of coral reef ecosystems. Remote sensing offers repeatable, quantitative assessments of habitat and environmental characteristics over spatially extensive areas. As the multi-disciplinary field of coral reef remote sensing continues to mature, results demonstrate that the techniques and capabilities continue to improve. New developments allow reef assessments and mapping to be performed with higher accuracy, across greater spatial areas, and with greater temporal frequency. The increased level of information that remote sensing now makes available also allows more complex scientific questions to be addressed. As defined for this book, remote sensing includes the vast array of geospatial data collected from land, water, ship, airborne and satellite platforms. The book is organized by technology, including: visible and infrared sensing using photographic, multispectral and hyperspectral instruments; active sensing using light detection and ranging (LiDAR); acoustic sensing using ship, autonomous underwater vehicle (AUV) and in-water platforms; and thermal and radar instruments. Emphasis and Audience This book serves multiple roles. It offers an overview of the current state-of-the-art technologies for reef mapping, provides detailed technical information for coral reef remote sensing specialists, imparts insight on the scientific questions that can be tackled using this technology, and also includes a foundation for those new to reef remote sensing. The individual sections of the book include introductory overviews of four main types of remotely sensed data used to study coral reefs, followed by specific examples demonstrating practical applications of the different technologies being discussed. Guidelines for selecting the most appropriate sensor for particular applications are provided, including an overview of how to utilize remote sensing data as an effective tool in science and management. The text is richly illustrated with examples of each sensing technology applied to a range of scientific, monitoring and management questions in reefs around the world. As such, the book is broadly accessible to a general audience, as well as students, managers, remote sensing specialists and anyone else working with coral reef ecosystems.
