This is a book about geography. It is also about Geographic Information Systems (GIS) – a fundamental set of automated ideas and concepts rooted in over 2500 years of explorations and geographic research (Dobson, 1995) and designed to provide answers to questions based on mapped data.

This study concern the quaternary geology, geomorphology and sedimentology of the intramontane Bandung basin, West - Java, Indonesia. A comprehensive analysis of the sequence of lacustrine, alluvial and volcaniclastic sediments in the basin form the basis for a reconsstrution of the Late Quanternary geologic and morphologic evolution of the Bandung basin area and for an evaluation of the geolog…
