Our transcription: Recently, a group of oil companies asked the Earth Satellite Corporation to investigate the potential for oil and gas reserves in Pakistan.
The idea was to get an integrated notion of oil and gas occurrence in Pakistan.
Of course, with the hope of: one, finding extensions of things that were known, and two, hopefully finding areas that had potential that really had not been examined in any detail or drilled for that matter.
The data gathered by satellite was beamed back to Earth as a stream of computerized information.
It did not look like a picture of Pakistan upon its arrival.
Because we record all of the information as a bunch of numbers, we can then use those numbers and apply mathematical techniques to them, which enhance the information or combine the information in different ways to get a product we want.
Different features on the Earth are sensitive to different portions of the electromagnetic spectrum.
Therefore, if you were interested in vegetation, we would use a different band combination.
Or if you're interested in urban areas, we'd select the band combination based on that, whatever you want to get out of the imagery.
