This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mangrove forests are critical to mitigating climate change and provide many essential benefits to their ecosystems and local environments but are under threat due to deforestation. However, monitoring mangroves through remote sensing can help pinpoint and alleviate the causes of their deforestation. Machine learning can be used with remotely sensed low-resolution satellite or high-resolution aerial imagery to automatically create mangrove extent maps with higher accuracy and frequency than previously possible. This study explores and offers recommendations for two practical scenarios. In the first practical scenario, where only low-resolution hyperspectral satellite imagery is acquired, we implemented several classical machine learning models and applied these results to data acquired in the Clarendon parish of Jamaica. We found that utilizing extensive feature engineering and hyperspectral bands can result in strong performance for mangrove extent classification, with an accuracy of 93% for our extremely randomized trees model. In the second practical scenario, we explored when there is full coverage of both low-resolution satellite and high-resolution aerial imagery over a survey area. We created a hybrid model which fuses low-resolution pixels and high-resolution imagery, achieving an accuracy of 97% when applied to a dataset based in Baja California Sur, Mexico, offering another high-performance method to automatically create mangrove extent maps if both high- and low-resolution imagery is available. Overall, the methods tested over these two scenarios provide stakeholders flexibility in data and methods used to achieve accurate, automatic mangrove extent measurement, enabling more frequent mangrove monitoring and further enabling the protection of these important ecosystems.

Download or read book Remote Sensing of Mangroves written by Nils Wolf and published by GRIN Verlag. This book was released on 2008-06-12 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essay from the year 2006 in the subject Geography / Earth Science - Miscellaneous, grade: 1,7, University of Sheffield, language: English, abstract: The purpose of this work is to describe the application of remote sensing in the field of mangrove mapping. The question will be about the appropriate imagery and the diversity of processing methods. But first of all: What makes mangrove distinctive as a remote sensing target? Therefore, mangroves will be introduced with its ecological and physical properties. Furthermore, its significance for humans and the environment will be pointed out, which enforces the need to take care of this ecologically sensitive environment. This is why one should integrate the mangroves into coastal management processes. This requires knowledge about mangroves in their ecological habitats, from the micro-level, interrogated in the laboratory, up to a macro-level, observed from airborne or satellite platforms. Remote sensing will be introduced as an appropriate tool to map the extent and different habitats of mangroves and also to monitor dynamics over time.
Download or read book Object Based Image Analysis written by Thomas Blaschke and published by Springer Science & Business Media. This book was released on 2008-08-09 with total page 804 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together a collection of invited interdisciplinary persp- tives on the recent topic of Object-based Image Analysis (OBIA). Its c- st tent is based on select papers from the 1 OBIA International Conference held in Salzburg in July 2006, and is enriched by several invited chapters. All submissions have passed through a blind peer-review process resulting in what we believe is a timely volume of the highest scientific, theoretical and technical standards. The concept of OBIA first gained widespread interest within the GIScience (Geographic Information Science) community circa 2000, with the advent of the first commercial software for what was then termed ‘obje- oriented image analysis’. However, it is widely agreed that OBIA builds on older segmentation, edge-detection and classification concepts that have been used in remote sensing image analysis for several decades. Nevert- less, its emergence has provided a new critical bridge to spatial concepts applied in multiscale landscape analysis, Geographic Information Systems (GIS) and the synergy between image-objects and their radiometric char- teristics and analyses in Earth Observation data (EO).

This book was released on 2021-06-02 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The great potential of remote sensing technologies for operational use in sustainable forest management is addressed in this book, which is the reprint of papers published in the Remote Sensing Special Issue “Operationalization of Remote Sensing Solutions for Sustainable Forest Management”. The studies come from three continents and cover multiple remote sensing systems (including terrestrial mobile laser scanning, unmanned aerial vehicles, airborne laser scanning, and satellite data acquisition) and a diversity of data processing algorithms, with a focus on machine learning approaches. The focus of the studies ranges from identification and characterization of individual trees to deriving national- or even continental-level forest attributes and maps. There are studies carefully describing exercises on the case study level, and there are also studies introducing new methodologies for transdisciplinary remote sensing applications. Even though most of the authors look forward to continuing their research, nearly all studies introduced are ready for operational use or have already been implemented in practical forestry.

This book was released on 2017-11-03 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive overview and analysis of mangrove ecological processes, structure, and function at the local, biogeographic, and global scales and how these properties interact to provide key ecosystem services to society. The analysis is based on an international collaborative effort that focuses on regions and countries holding the largest mangrove resources and encompasses the major biogeographic and socio-economic settings of mangrove distribution. Given the economic and ecological importance of mangrove wetlands at the global scale, the chapters aim to integrate ecological and socio-economic perspectives on mangrove function and management using a system-level hierarchical analysis framework. The book explores the nexus between mangrove ecology and the capacity for ecosystem services, with an emphasis on thresholds, multiple stressors, and local conditions that determine this capacity. The interdisciplinary approach and illustrative study cases included in the book will provide valuable resources in data, information, and knowledge about the current status of one of the most productive coastal ecosystem in the world.
