Abstract

This study investigates the relation between morphological spatial orientation features, lineaments trends and geological structures in the southern slope of Merapi Mountain in Yogyakarta, Indonesia. Digital processing using Landsat 8 OLI/TIRS and digital elevation model data 30 m resolution to construct and extract automatically identifying structure lineaments and stream network. Azimuth frequency and length density distribution analyze from morphological features. Geological structure controls the landscape were analyzed use profile data from the southerly flowing stream. The structure trends north-south were profiles taken with the topo-relief changes between the slightingly gradient and the depth of mountain front in the part of the south mountain slope. Dendritic-trellis stream modification types show different anomaly along surface stream profile intersects with fault and lineaments. Azimuth lineaments analysis indicating north-south, east-west, northeast-southwest, and northwest-southeast trends compared with stream surface flow system, the direction classification show similarity structures control trends in the geomorphological surface. These lineament structures provide cannelure for surface water flow. The lineaments form extraction divided into three population bases on an outcrop of the host rock, to getting information of geologic time trend evolution. Lineament trend spread into different lithology because of tectonic activity from the weak zone of surface discontinuity from the recent surface landscape.
