Download or read book Land Cover Change Analysis of Big Creek Conservation Area with Satellite Remote Sensing written by Chen Shang and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the relatively complex land cover configuration and a series of significant ecological implications, the issue of land cover changes in the Big Creek area are of critical value to environmental conservation groups, policy makers, and relevant stakeholders. In consultation with the Carolinian Canada Coalition (CCC), the potential of IKONOS imagery as a high spatial resolution remote sensing product is assessed for significant habitat mapping, and a change detection methodology is developed and implemented for the Big Creek area that will be of value to decision makers and policy analysts. In order to take advantage of the synergistic strengths of multiple change detection techniques, a hybrid approach is adopted in this study, aiming to detect and stratify land cover changes over the time span from 2004 to 2012. On the basis of an assessment of the capability of differentiating changed from unchanged areas, the image differencing method based on Normalized Difference Vegetation Index (NDVI) was found to be the most accurate among the three change detection techniques employed in this study. As an attempt to incorporate local spatial autocorrelation information into the change detection analysis, the Getis statistic was used as a spatial filter in conjunction with the image differencing technique, and it showed great promise for improving the change/no change maps both qualitatively and quantitatively. In particular, the extreme Getis statistic proposed in this study demonstrated strong potential for automatically determining the optimal scale for spatial smoothing, which could greatly improve the efficiency and accuracy of change detection practices. In addition, the performance of the post-classification comparison approach was found to be highly dependent on the intrinsic characteristics of the individual classified maps, rather than simply the accuracy scores of the classifications subject to the comparison. Therefore, it is recommended that a benchmark approach be taken to compensate for this uncertainty of the post-classification comparison method, such that the negative impact of the misclassification errors in the individual classified maps could be reduced to an acceptable level. The findings of this research will contribute to a better understanding of the usefulness of some widely used change detection techniques in a relatively complex physical environment with abundant vegetation cover. In addition, the application of the Getis statistic as a spatial filter is proven useful for suppressing potential "salt and pepper" effects in the context of change detection analysis, especially if high spatial resolution imagery is employed. With minor modifications, the workflow proposed in this study is likely to reliably fulfill the purpose of monitoring land cover dynamics in other environments as well. However, it should be noted that clear awareness of the characteristics of the study area and needs of information is a premise to the successful application of any change detection approach in different environments.

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.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Studying how the Earth's surface changes with time allows conservation managers a better understanding of land cover and composition for research and environmental management. Knowledge of where and when change occurs is important to land management and conservation in Canada. Satellites, like the U.S. Geological Survey's (USGS) Landsat 8, provide a regularly updated sequence of images that are used in various terrestrial monitoring approaches. In the Canadian context, Landsat 8 typically yields one or two clear images each growing season for any given location. The European Space Agency's (ESA) pair of Sentinel 2 satellites, perform marginally better in the Canadian context due to their higher resolution and more frequent revisit times. Separately, either system has limited potential to construct a time-series of clear observations for change detection. However, because of their technical compatibility combining Landsat-8 and Sentinel 2 data can enrich the total pool of clear Earth observations and make it possible to improve terrestrial monitoring approaches. This is particularly helpful for creating annual composite images to represent a growing season across an expansive region that can not otherwise be captured in one image. Using composited data, monitoring programs construct time series for trend-based detection of land-use / land-cover (LULC) change (i.e., disturbance). There are limits to constructing time series of change detection in this way, however. For example, if a method collects images from August 1st plus/minus thirty days to create a single clear image to represent peak growing season vegetation, then changes after this compositing period are not captured. Moreover, because terminal years of the time series lack a subsequent year of observations to confirm trends and values, change detection in terminal years is less certain than intermediate years. To try and resolve these issues, this thesis develops a novel classification method, dubbed Shrinking Latency in Multiple Streams (SLIMS), to combine two open-access satellite image streams (Landsat 8 and Sentinel 2). SLIMS captures the within-year spectral signature of forest disturbance and creates a sequence of near real-time classifications of forest disturbance. Subsequently, this thesis combines SLIMS with the Bayesian Updating of Land Cover (BULC) algorithm to synthesize these unpolished, individually noisy land cover classifications into a series of more accurate land cover classifications. Using a free and accessible cloud-based computing platform (i.e., Google Earth Engine), this work computes a forest change time series at a fine spatial resolution (10 metre) and very fine time slices (~5 days) to provide more detailed information concerning forest disturbances to conservation managers. This thesis discusses the opportunities and challenges of improving annual scale trend-based change detection approaches like the Canadian Forestry Service's Composite to Change (C2C) algorithm, namely in the a) time of compositing and b) the terminal years of a time series"--
