Document Summary
Data acquisition techniques: the bases for multispectral collection and analysis is that of examined areas or objects that reflect or emit radiation that stand out from surrounding areas. Sensor platforms: ground-based, airborne, which include: various versions of aircrafts, with equipment attached on them, spaceborne, which include: geoeye, worldview, quickbird, ikonos-1. Remote sensing is the science and art of obtaining information about an object, area or phenomenon through the analysis of data acquired by a device that is not in contact with the object, area, or phenomenon under investigation. Science and art this is b/c it can be both, or one, but not neither. Not in contact this is b/c it never involves the direct physical touch of anything, but is from far away. The modern discipline of remote sensing is new. 1847: properties of infrared similar to visible light. 1920-30: development and application of aerial photography and photogrammetry.
