Available in PDF, EPUB and Kindle. Book excerpt: Urban expansion into areas of chaparral vegetation has greatly increased the danger of wildland fires in settled areas, particularly in southern California. Fires in Topanga Canyon, for example, have been especially severe. Reliable methods of predicting the potential hazard for chaparral fires to man and his settlements in such areas are needed. Aerial photography, using color infrared film, was examined to determine potential fire hazard in Topanga Canyon, and maps indicating potential fire hazard were constructed. A subsequent field survey verified the accuracy of these maps, though the failure to obtain stereoscopic coverage of the study area resulted in a general underestimation of slope as a factor in fire hazard analysis. Remote sensing techniques, especially the use of color infrared aerial photography, provide a useful tool for fire hazard analysis, including interpetive information about fuel volumes, physiognomic plant groupings, the relationships of buildings to both natural and planted vegetation, and fire vulnerability of roofing materials. In addition, the behavior of the September, 1970 Wright Fire in the Topanga study area suggested the validity of the fire potential analysis which had been made prior to that conflagration. (Author).

Download or read book Wildland Fire Danger Estimation And Mapping The Role Of Remote Sensing Data written by Emilio Chuvieco and published by World Scientific. This book was released on 2003-09-29 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents a wide range of techniques for extracting information from satellite remote sensing images in forest fire danger assessment. It covers the main concepts involved in fire danger rating, and analyses the inputs derived from remotely sensed data for mapping fire danger at both the local and global scale. The questions addressed concern the estimation of fuel moisture content, the description of fuel structural properties, the estimation of meteorological danger indices, the analysis of human factors associated with fire ignition, and the integration of different risk factors in a geographic information system for fire danger management.

Download or read book Spatial and Temporal Variation in Biomass Accumulation in Southern California Chaparral written by Kellie Ann Uyeda and published by . This book was released on 2015 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildfires are a common occurrence in chaparral shrublands, and post-fire patterns of biomass accumulation are important for understanding ecosystem productivity and fuel available for future fires. In this research, I examine patterns of biomass accumulation in southern California chaparral shrublands at early and late stages of post-fire recovery using a combination of detailed field work and remote sensing. Using field measurements of a site with adjacent stands of varying ages and high spatial resolution imagery, I examine patterns of species composition and associated levels of biomass to characterize long-term patterns in biomass accumulation. I also evaluate the potential for utilizing shrub growth ring widths to track annual biomass accumulation in the first decade of post-fire recovery, and test for the relationship between biomass and spatial variation in factors related to the energy and water balance. In addition, I examine the potential for extending the use of shrub growth rings to track biomass across larger spatial extents using satellite-based growth metrics. The study of stands of varying ages reveals that biomass shows substantial variation even within stands of the same age, and that species composition is different in younger stands of chaparral compared to the more mature stands. In the study of growth rings, I find that while measuring growth rings widths is a valuable method for tracking biomass accumulation in the first decade following a fire, there is no apparent relationship between biomass and factors related to the energy and water balance. Annual biomass growth, as estimated from shrub growth ring widths, shows a promising relationship with satellite-based metrics of annual growth, indicating the potential for further study of the relationship over larger spatial extents.
Download or read book Earth Observation of Wildland Fires in Mediterranean Ecosystems written by Emilio Chuvieco and published by Springer Science & Business Media. This book was released on 2009-09-25 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildland fires are becoming one of the most critical environmental factors affecting a wide range of ecosystems worldwide. In Mediterranean ecosystems (including also South-Africa, California, parts of Chile and Australia), wildland fires are recurrent phenomena every summer, following the seasonal drought. As a result of changes in traditional land use practices, and the impact of recent climate warming, fires have more negative impacts in the last years, threatening lives, socio-economic and ecological values. The book describes the ecological context of fires in the Mediterranean ecosystems, and provides methods to observe fire danger conditions and fire impacts using Earth Observation and Geographic Information System technologies.

Download or read book Remote Sensing Techniques Aid in Preattack Planning for Fire Management written by Lucy Anne Salazar and published by . This book was released on 1982 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remote sensing techniques were investigated as an alternative for documenting selected preattack fire planning information. Locations of fuel models, road systems, and water i sources were recorded by Landsat satellite imagery and aerial photography for a portion of the Six Rivers National Forest in northwestern California. The two fuel model groups used were from the 1978 National Fire Danger Rating System and the Northern Forest Fire Laboratory. Landsat-derived fuel model data were digitized and computer analyzed by unsupervised and guided clustering techniques to produce a fuel model map of the area. Overall Landsat classification accuracies of fuel models were moderate-71 percent. This was mainly due to the incompatibilities found between fuel model descriptions and remote sensing capabilities. The results suggest, however, that a basic preattack plan that is moderately reliable, quickly attainable, and easily updated is feasible by applying remote sensing techniques.

Download or read book Operationalization of Remote Sensing Solutions for Sustainable Forest Management written by Gintautas Mozgeris and published by MDPI. 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.
