Paper Abstract

The Optical Mapping Instrument (OMI) is intended to operate from a low earth orbit spacecraft, such as the Columbus Polar platform, and produce very high spatial resolution images of the ground, suitable for the manufacture of both conventional maps and digital elevation models. The instrument concept is based on the use of two fixed telescopes viewing in different directions along the sub-satellite track. The same area ground is viewed by each telescope within about a minute and a stereo pair of images thus produced. Processing of the images on the ground produces the appropriate cartographic product. OMI operates primarily in the near-infrared part of the spectrum and will produce a spatial resolution of approximately 5m over a swath of 60km. Secondary functions being considered for the instrument are an even better resolution over a reduced field of view, additional spectral bands in the visible and near-infrared, and a high spectral resolution mode.
