According to Sampurno 1975 this area has many experiences of suffering hazard from landslides compared to other areas. Those hazard are progressively
felt nowadays due to mass movements or landslide is endangering human life and their properties, such as houses, roads and rail roads, rice fields and farms, ranch,
irrigation channel and others. Although landslide is influenced by steepness of slope factor, rain falls,
water stream, vegetation, and the result of man activities such as digging and others that can enlarger particular slope angle, however the major dominant
control factor of those hazard is beginning from geologic structure which includes stratigraphic implications and tectonic activities to constructs the land forms from
within the earth’s. In the framework of this research, GIS and remote sensing technology will
be used to determine geological hazard sensitive area. Remote sensing is used for geological interpretation such geomorphology, drainage and structure patterns
which indicate the general tectonic patterns. While GIS is used for spatial analysis to determine geological hazard sensitive area by overlying the geological
interpretation result with geologic map and other maps that required in analysis.
1.2 Scope of The Research
Geological hazard is disaster generated by effect of direct or indirect corresponding natural phenomenon with geologic processes including man.
The scope of this research is how GIS and Remote Sensing technology simultaneously can be used to determining geological hazard sensitive area based
on geomorphological interpretation from satellite imagery, distribution of rocks and minerals characteristics and degree of slope steepness.

1.3 Objectives
The main purpose of the research is using GIS and Remote Sensing technology to determine sensitive area based on geological hazard perspectives. It
will have a function to support a decision support system in order to take decision for placement of settlement location in West Java area. The result will contribute
as a knowledge base which can be utilized by public, city planners, city officials and also policy makers to make future decision concerning the places of suitable
settlement in order to obtain the sustainable development.
1.4 Benefit of Research
The core and simultaneously benefit of this research is how GIS and Remote Sensing technology will helps geoscientist especially geologist to capture,
manipulate and analyze of information about an object without physical contact as preliminary survey reconnaissance, mainly for geomorphic study of areas that
are inaccesible to field-base investigation. Moreover, by utilizing the available

sources of data data provider GIS and Remote Sensing can be used more effective and efficient compared to the current or traditional methods particularly
for interpreting extremely large cover research area. Finally, the result of the research will be mapped in digital and paper forms
that come with additional data showing further information, created with GIS software and intentionally published in digital map which entitled as Geological
Hazard Sensitive Area Map.
