Abstract

PurposeThe purpose of this paper is to utilise the interactive view capability of the geographical information system (GIS) for the geological interpretation in Klang Valley, Malaysia.Design/methodology/approachTopographical map scale of 1:10 000 was used to generate digital elevation model (DEM). The geological map was draped over the DEM to create a 3D perspective view. The geological interpretation was undertaken using the 3D capability of the GIS software.FindingsFrom the study, five lineaments which could possibly be the newly identified faults and one lithological boundary have been delineated.Research limitations/implicationsAlthough these findings need to be rechecked in the field, they show the capability of the DEM application in structural geology interpretation.Practical implicationsThe results obtained from this study demonstrate the capability of utilising a geological map draped over DEM for structural geological interpretation. Thus the technique may increase the interpretation accuracy.Originality/valueThe major outcome of this research is the possible use of DEM in the application of geological study.
