PREFACE

The COSPARSymposium S.2 on Resource Mapping and Geophysical Surveysusing Space Technology received a good response which is indicative ofcurrent scientific interest in this highly jspecialized and applicationoriented field. The Symposium did meet a part of the objective for which itwas organized. However, the objective of the Symposium in this field isgrowing and expanding and depends on the development newer techniques ofmapping and surveying using space technology. It is important to note thatthe full and effective utilization of space technology is coupled withdetailed study of ground truths using extended spectrum of electromagneticwaves. In this Symposium four of the eight invited papers were presentedwhich covered important areas of on-going Resource Mapping and GeophysicalSurveys. The potentiality of MAGSAT data reduction to allocate crustalanomaly, magnetic anomaly which is capable of providing much sought forinsight into the tectonic evolution and related information. The applicationof geophysical and geochemical data for mineral exploration was projected inthe interpretation of remote sensing imagery. The importance of airbornegamma—ray survey was presented which is of paramount importance for locatingsources of radioactive materials. The importance of ground truths obtainedby conventional geophysical surveys in the interpretation of satellite datawas projected and emphasised. The continuing projection of ongoing modellingand interpretation of data in future symposia would surely bring out manyaspects of resource mapping that are not yet known or fully developed.
