Tapping on a range of techniques provided in the Erdas Imagine environment, the procedures laid out in this paper go a step further than normal software guidelines by providing improvised techniques that are graphically illustrated by reference to a study area (the Okavango Delta in northern Botswana) covering about 65000km to allow the reader to assimilate the sequence of steps involved. With self evident usable results in the form of a 2m-resolution seamless mosaic providing blanket coverage for the above stated area on 15 September 1967, it is apparent that similar initiatives elsewhere can take advantage of our proposed methodology in putting together what is retrievable from the archives by building databases that extend time horizons into the historical past for use in long-term environmental monitoring.
