Surface Temperature Mapping Of The University Of Northern Iowa Campus Using High Resolution Thermal Infrared Aerial Imagery, Alexander Savelyev

Dissertations and Theses @ UNI

The goal of this study was to produce and analyze a heat loss map of the University of the Northern Iowa campus using thermal infrared remote sensing data. Aerial data with the spatial resolution of 0.29m and radiometric resolution of 14 bit was collected. A model for the pixel to radiance and temperature conversion was developed with its parameters estimated with an R² of 0.78. Temperature imagery was shown to be consistent over the time of the survey and accurate to within 12°C. The temperature map then was used to assess the conditions of the rooftops and steam pipelines …

Surface Temperature Mapping Of The University Of Northern Iowa Campus Using High Resolution Thermal Infrared Aerial Imageries, Alexander Savelyev, Ramanathan Sugumaran

Faculty Publications

The goal of this project was to map the surface temperature of the University of Northern Iowa campus using high-resolution thermal infrared aerial imageries. A thermal camera with a spectral bandwidth of 3.0-5.0 µm was flown at the average altitude of 600 m, achieving ground resolution of 29 cm. Ground control data was used to construct the pixelto-temperature conversion model, which was later used to produce temperature maps of the entire campus and also for validation of the model. The temperature map then was used to assess the building rooftop conditions and steam line faults in the study area. Assessment …
