  • Airborne scanner image spectrometer
    Patent number: 5471056
    Abstract: A system for making airborne surveys uses first and second surveys made at opposite points on the thermal cycle and collects hyper-spectral image data forming continuous bands in the visible, solar infrared and thermal infrared regions.
    Type: Grant
    Filed: May 23, 1994
    Date of Patent: November 28, 1995
    Assignee: Texaco Inc.

  • Method for airborne surveying which includes the determination of the apparent thermal inertia of the material being surveyed
    Patent number: 5445453
    Abstract: A method for airborne surveying is disclosed to acquire, process and calculate the apparent thermal inertia of earth surface materials during flight and by post-flight processing. Two separate airborne surveys are conducted during a diurnal solar cycle to determine the maximum and the minimum radiant temperatures of the earth surface materials. The albedo of the earth material is determined and is used to calculate the apparent thermal inertia of the earth surface materials. Spatial rectification of the two surveys is accomplished by use of differential global positioning.
