It is important to distinguish between the terms images and photographs in remote sensing. Interpretation and Analysis (F) 7. Photos are normally recorded over the wavelength range from 0.3 m to 0.9 m - the visible and reflected infrared. https://doi.org/10.1007/978-3-030-82327-6_1, DOI: https://doi.org/10.1007/978-3-030-82327-6_1, eBook Packages: EngineeringEngineering (R0). Application (G) 9 10. Hyperspectral Remote Sensing Collects image data in many narrow contiguous spectral bands through the visible and infrared portions of spectrum The band width is < 10nm 1mm = 1,000mm 1mm= 1,000nm http://en.wikipedia.org/wiki/Hyperspectral_imaging Photographic film has the clear advantage of recording extremely fine spatial detail, since individual silver halide molecules can record light sensitivity differently than their neighbouring molecules. Chapter One Shahjalal University of Science & Technology Remote sensing and image interpretation 1. Determining the structural arrangements of disturbed strata, such as folds and faults (structural geology). Remote Sensing Hyperspectral Remote Sensing - [PPT Powerpoint] 2003b) was previously utilized in a remote sensing context by Gualtieri and Cromp in 1998 and Pal and Mather, 2005.

By combining different channels of imagery representing different wavelengths, we may be able to identify combinations of reflectance between the different channels which highlight features that we would not otherwise be able to see, if we examine only one channel at a time. Orbit selection can vary in terms of altitude (their height above . The information from a narrow wavelength range is gathered and stored in a channel, also sometimes referred to as a band.
