The geometric rectification of remotely sensed data, acquired using airborne platforms, is an essential prerequisite for quantitative processing and analysis, due to the complex distortions inherent in such imagery. The Natural Environment Research Council (NERC) has implemented an Integrated Data System (IDS) on-board its survey aircraft to derive both attitude and position for use in a parametric solution to the geometric correction of data from two airborne sensors. This paper describes the elements of the NERC IDS and the complementary ground data processing system that carries out navigation pre-processing and geometric resampling of the airborne data. Test flights have been flown and processed to demonstrate the potential of this completely GPS-based solution to providing high quality, spatially referenced, data for use in environmental monitoring applications. 6 refs., 5 figs., 1 tab.
