A Multi-Scale Analysis Of Census-Based Land Surface Temperature Variations And Determinants In Indianapolis, Indiana, Bingqing Liang May 2005

A Multi-Scale Analysis Of Census-Based Land Surface Temperature Variations And Determinants In Indianapolis, Indiana, Bingqing Liang

All-Inclusive List of Electronic Theses and Dissertations

Mapping urban temperatures are one of the major foci in urban climatology studies due to its close relationships with environmental, economic, and social issues. Most previous urban temperature studies were based on a single scale. This study utilized remote sensing and GIS data to perform a multiple scale analysis of urban temperatures. Land surface temperatures (LST) data derived from a Landsat Enhanced Thematic Mapper Plus (ETM+) image were used to examine census-based variations and to model their numerical relationships with urban morphology in Marion County, Indiana. Selected variables for the urban morphology include Normalized Difference Vegetation Index (NOVI), buildings, roads, …

A Spatial And Temporal Analysis Of Riparian Vegetation Along Satus Creek On The Yakama Indian Reservation, Kathryn Gellenbeck Jan 1999

A Spatial And Temporal Analysis Of Riparian Vegetation Along Satus Creek On The Yakama Indian Reservation, Kathryn Gellenbeck

All Master's Theses

Satus Creek provides critical habitat for the Yakima River Basin steelhead. A diverse community of riparian vegetation is important for healthy fish habitat; vegetation changes can affect shade, cover, channel structure, water quality, and food availability. The purpose of this thesis is to analyze and illustrate riparian vegetation change, both temporally and spatially, along three separate reaches of Satus Creek. A Geographic Information Systems approach was applied to assess the vegetation change by comparing plant species composition and density on 1949 and 1995 aerial photographs. The GIS approach allowed patterns and trends in the vegetation to be identified. In less …

Regional Variation In Temperature Humidity Index For Poultry Housing, Richard S. Gates, Hanzhong Zhang, Donald G. Colliver, Douglas G. Overhults Jan 1995

Regional Variation In Temperature Humidity Index For Poultry Housing, Richard S. Gates, Hanzhong Zhang, Donald G. Colliver, Douglas G. Overhults

Biosystems and Agricultural Engineering Faculty Publications

A building thermal model was used to compute hourly values of temperature humidity index (THI) for a broiler house with and without an evaporative misting system. Hourly summer time weather data for 238 U.S.A. locations covering 30 years were used to develop extreme occurrences of THI. Results were incorporated into a Geographical Information System (GIS) database to create isolines of THI and percentage of hours exceeding a heat stress threshold. Regional variations in misting as a suitable cooling technique are presented in terms of hours reduction in annual heat stress. The technique may be used for assisting in management decisions …
