| Summary: | Software usage in the study of geological sciences are increasingly needed to
make geological tasks both indoor and outdoor became much easier. The main
superiority of this method is its practical. This research is planned to measure
how good are softwares capability in processing geological data. The research
area is located in Kabupaten Kulonprogo, Daerah Istimewa Yogyakarta.
According to the past research, most of research area are Old Andesite of
Bemmelen Formation which is dominated by volcanic processes and estimated as
an aged eroded caldera.
Some softwares are being used ini this research to analyze several kinds of
remote sensing data. ArcGIS is used to analyze morphology and slopes with some
functions called hillshade, slope, and aspect. PCI Geomatica Focus has an ability
to automatically extract lineament data from a raster image. Which then used to
analyzed the general direction of the force that controls that area. ER Mapper is
used to process landsat image which will displays appearance that suit the type of
analysis. Those output are then combined and analyzed with automatic or manual
method to provide the information we need.
The result shows that the morphology and lineament in the research area are
basically rounded and some of them characterize a parts of caldera such as outer
wall, inner wall, topographic rim andresurgent dome
