ABSTRACT
Indonesia is one of the countries that cannot escape from the geohazard. So, monitoring system is one of the important activities to reduce the victims. The challenge is how to make the low-cost monitoring system that suitable for Indonesia. This paper focus on the landslide and the volcano hazard. The choice is to use digital photogrammetry that equipped with the consumers grade instrument. As a consequence, the special processing should be implemented to improve the ability of the consumer’s grade equipment. Further, this paper explains the basic system abilities, the processing, and some sample cases. The specific camera calibration procedure was developed to improve the geometric quality. The advantages of using the system was described such as the low-cost operation, the fast 3D modeling, and 3D deformation vector for point or plane. This monitoring method can be worked as a supplement to enhance the existing system.
