A Global Regression Method For Thermal Sharpening Of Urban Land Surface Temperatures From Modis And Landsat, James. W. Wang, Winston T. L. Chow, Yi-Chen Wang
A Global Regression Method For Thermal Sharpening Of Urban Land Surface Temperatures From Modis And Landsat, James. W. Wang, Winston T. L. Chow, Yi-Chen Wang
Research Collection School of Social Sciences
Land surface temperatures (LST) in urban landscapes are typically more heterogeneous than can be monitored by the spatial resolution of satellite-based thermal infrared sensors. Thermal sharpening (TS) methods permit the disaggregation of LST based on finer-grained multispectral information, but there is continued debate over which spectral indices are most appropriate for urban TS, and how they should be configured in a predictive regression framework. In this study, we evaluate the stability of various TS kernels with respect to LST at different spatial (Landsat 8) and diurnal (MODIS) scales, and present a new TS method, global regression for urban thermal sharpening …

Impervious Surfaces And Water Quality: A Review Of Current Literature And Its Implications For Watershed Planning, Elizabeth Brabec
Impervious Surfaces And Water Quality: A Review Of Current Literature And Its Implications For Watershed Planning, Elizabeth Brabec

Impervious surfaces have for many years been recognized as an indicator of the intensity of the urban environment and, with the advent of urban sprawl, they have become a key issue in habitat health. Although a considerable amount of research has been done to define impervious thresholds for water quality degradation, there are a number of flaws in the assumptions and methodologies used. Given refinement of the methodology, accurate and usable parameters for preventative watershed planning can be developed, which include impervious surface thresholds and a balance between pervious and impervious surfaces within a watershed.

Impervious surfaces have for many years been recognized as an indicator of the intensity of the urban environment and, with the advent of urban sprawl, they have become a key issue in habitat health. In addition to the direct impacts to water quality, impervious surfaces fragment open space and habitat and are therefore a primary land use indicator of both water quality and ecological degradation. This paper develops an understanding of the land use planning implications of the interaction of impervious surfaces, water quality and the spatial form those surfaces take in a watershed. In order to clarify these relationships, …
