Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a protocol for assessing the predictive accuracy of thematic maps. Although developed during the Cariboo Predictive Ecosystem Mapping (PEM) pilot, the Canim Lake PEM operational prototype, and the Quesnel PEM to test the accuracy of predictive ecosystem maps, this protocol is applicable to many thematic maps. The Protocol for Accuracy Assessment of Ecosystem Maps (Meidinger 2003) incorporates many of the concepts presented here, but recent work done on the Canim Lake and Quesnel PEMS suggests that a more detailed operational protocol is needed to ensure the integrity of the data collected. In addition to detailed instructions and specifications for data collection, this paper describes a staged sampling protocol designed to minimize the sampling cost required to attain a specified level of confidence in the assessed accuracy.

Available in PDF, EPUB and Kindle. Book excerpt: This report outlines a protocol for assessing the thematic accuracy of large-scale ecosystem mapping. The protocol presents a statistically unbiased approach to evaluating the acceptability or accuracy of the mapping. The thematic content of randomly selected map polygons, or small areas, is assessed by various means, with the methods varying in precision & objectivity. The protocol requires the development of a sampling plan that articulates decisions about such matters as protocol level, sample size, assessment method, and target error. The approach outlined in this protocol provides a means of obtaining some overall, statistically valid scores to rate the accuracy of predictive ecosystem mapping, terrestrial ecosystem mapping, or other ecosystem maps. The results can be used as a component of quality assurance or for presenting statistics on the accuracy of mapping.

Download or read book Digital Soil Mapping with Limited Data written by Alfred E. Hartemink and published by Springer Science & Business Media. This book was released on 2008-07-11 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Signi?cant technological advances have been few and far between in the past approximately one hundred years of soil survey activities. Perhaps one of the most innovative techniques in the history of soil survey was the introduction of aerial photographs as base maps for ?eld mapping, which replaced the conventional base map laboriously prepared by planetable and alidade. Such a relatively simple idea by today’s standards revolutionized soil surveys by vastly increasing the accuracy and ef?ciently. Yet, even this innovative approach did not gain universal acceptance immediately and was hampered by a lack of aerial coverage of the world, funds to cover the costs, and in some cases a reluctance by some soil mappers and cartog- phers to change. Digital Soil Mapping (DSM), which is already being used and tested by groups of dedicated and innovative pedologists, is perhaps the next great advancement in delivering soil survey information. However, like many new technologies, it too has yet to gain universal acceptance and is hampered by ignorance on the part of some pedologists and other scientists. DSM is a spatial soil information system created by numerical models that - count for the spatial and temporal variations of soil properties based on soil - formation and related environmental variables (Lagacheric and McBratney, 2007).

Download or read book Applications of Small Unmanned Aircraft Systems written by J.B. Sharma and published by CRC Press. This book was released on 2019-10-18 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in high spatial resolution mapping capabilities and the new rules established by the Federal Aviation Administration in the United States for the operation of Small Unmanned Aircraft Systems (sUAS) have provided new opportunities to acquire aerial data at a lower cost and more safely versus other methods. A similar opening of the skies for sUAS applications is being allowed in countries across the world. Also, sUAS can access hazardous or inaccessible areas during disaster events and provide rapid response when needed. Applications of Small Unmanned Aircraft systems: Best Practices and Case Studies is the first book that brings together the best practices of sUAS applied to a broad range of issues in high spatial resolution mapping projects. Very few sUAS pilots have the knowledge of how the collected imagery is processed into value added mapping products that have commercial and/or academic import. Since the field of sUAS applications is just a few years old, this book covers the need for a compendium of case studies to guide the planning, data collection, and most importantly data processing and map error issues, with the range of sensors available to the user community. Written by experienced academics and professionals, this book serves as a guide on how to formulate sUAS based projects, from choice of a sUAS, flight planning for a particular application, sensors and data acquisition, data processing software, mapping software and use of the high spatial resolution maps produced for particular types of geospatial modeling. Features: Focus on sUAS based data acquisition and processing into map products Broad range of case studies by highly experienced academics Practical guidance on sUAS hardware, sensors, and software utilized Compilation of workflow insights from expert professors and professionals Relevant to academia, government, and industry Positional and thematic map accuracy, UAS curriculum development and workflow replicability issues This book would be an excellent text for upper-level undergraduate to graduate level sUAS mapping application courses. It is also invaluable as a reference for educators designing sUAS based curriculum as well as for potential sUAS users to assess the scope of mapping projects that can be done with this technology.
