Available in PDF, EPUB and Kindle. Book excerpt: The goal of this research is to develop a new approach to remote sensing thematic accuracy assessment in which the spectral distances between the classes in a thematic classification are used as inputs to the error estimation process. The conceptual basis for this new approach is that the confusion of relatively spectrally different classes represents a more severe error than confusing relatively spectrally similar classes. Therefore, the accuracy estimate of a classification can be adjusted to take into account the 'spectral severities' (or misclassification costs) of the errors in that classification. The benefits of including inter-class spectral distances in the accuracy assessment process are shown in the context of the development of two new accuracy assessment measures called Spectrally Weighted Kappa (SWK) and Spectrally Weighted Fuzzy (SWF). These two new accuracy assessment methods are introduced and tested for their performance relative to current techniques. The results of this research demonstrate that inter-class spectral distances can be used effectively in accuracy assessment of thematic classifications. The SWK approach can provide information about the spectral costs of errors in a classification that is not as apparent with traditional methods. In addition, SWK provides a quantitative base for establishing weights for Weighted Kappa analysis and allows for the possibility of improving a classification during its development. The SWF method improves upon current fuzzy accuracy assessment techniques by providing a way to establish membership functions that is based on inter-class spectral distances. We have shown that the SWF method can provide fuzzy membership values that are similar to those that a well-trained human might choose. Therefore, in cases where multiple interpreters would normally have been used to create fuzzy membership values, the SWF method can be employed reduce inter-interpreter bias. In addition, the SWF method provides a quanti.

This book was released on 2021-07-30 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Land cover assessment and monitoring of its dynamics are essential requirements for the sustainable management of natural resources, environmental protection, food security, humanitarian programmes as well as core data for monitoring and modelling. Land Cover (LC) data are therefore fundamental in fulfilling the mandates of many United Nations (UN), international and national institutions and programmes. Despite the recognition of such importance, current users of LC data still lack access to sufficient reliable or comparable baseline LC data. These data are essential to tackle the increasing concerns in regard to food security, environmental degradation, and climate change. Critically, maintaining and restoring land resources plays a vital task in tackling climate change, securing biodiversity, and maintaining crucial ecosystem services, while ensuring resilient livelihoods and food security.

Available in PDF, EPUB and Kindle. Book excerpt: The book describes the carefully made measurements in the pasture and rainforest at a series of sites across Amazonia. The data are analysed and interpreted to allow them to be used as the basis of accurate and realistic description of the land surface in the global circulation model which are used to predict the climate effect of large scale deforestation. Results are presented at all scales: for the centimetre scale of leaf and soil moisture measurementes, the field scale of micrometeorological flux measurements, through to the scale of meteorological models which predict the climate of the whole Amazonian basin.

Book Synopsis Field Methods in Remote Sensing by : Roger M. McCoy
Download or read book Field Methods in Remote Sensing written by Roger M. McCoy and published by Guilford Press. This book was released on 2005-01-01 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This concise, much-needed guide takes readers step by step through planning and executing field work associated with many different types of remote sensing projects. Remote sensing texts and research reports typically focus on data-analytic techniques while offering a dearth of information on procedures followed in the field. In contrast, this book provides clear recommendations for defining field work objectives, devising a valid sampling plan, finding locations using GPS, and selecting and using effective measurement techniques for field reflectance spectra and for studies of vegetation, soils, water, and urban areas. Appendices feature sample field note forms, an extensive bibliography on advanced and specialized methods, and online metadata sources.
