Conclusions Use 3S technique and a complete monitoring and
management system to provide complex type of hazards’ real-time data.
Integrate information and data from agencies by OGC’s SWE standard.
The portable unit includes PAC, battery, communication, CCD camera, geophone, handy rain gauge, soil moisture sensor and Sweet Swe Server.
The portable unit had been approved a success on monitoring landslide and providing SWE-standard data to different agencies.
