Understanding Satellite Imaging Technology — Part 3 of 3Orthorectification: Turning Satellite Images into Accurate Maps
1. IntroductionIn Part 1, How Do Satellites Capture Images of the Earth?, we explored three fundamental imaging methods: Frame Imaging, Pushbroom Imaging, and Whiskbroom Imaging. In Part 2, Geometric Distortions in Satellite Imagery, we examined why satellite images contain geometric distortions and how sensor models, including the Rational Function Model (RFM) and its Rational Polynomial Coeffi..
