Derivation Of The Transformation Relationship Of Pseudo-Invariant Features Of Two Landsat Images, Jeffrey R. Sefl Apr 1983

Derivation Of The Transformation Relationship Of Pseudo-Invariant Features Of Two Landsat Images, Jeffrey R. Sefl

Theses

The purpose of this effort was to determine the relationships of the spectral radiance distributions of pseudo-invariant features for a selected pair of Landsat images. The relationships for the four bands (band 4 through band 7) were determined to be linearly related. The transformation equations will map one images brightness values on to a second images brightness values.


Investigation Of The Radiometric Integrity Of The Theogram After Its Raster Scan Lines Are Removed Through Spatial Filtration, Joan Allamena Jan 1983

Investigation Of The Radiometric Integrity Of The Theogram After Its Raster Scan Lines Are Removed Through Spatial Filtration, Joan Allamena

Theses

Thermograms are records of density levels which correspond to apparent temperatures. The process of thermographic imaging is based on Plank's law which relates temperature to radiance. It begins with the collection of quantum energy which is then converted to voltage. The voltage powers a light source to expose the recording material of the thermogram. Atmospheric effects must also be taken into consideration. The relationship which takes all variables into account can be found in appendix A.
