Multi-layer compaction automatic monitoring equipment 
Base on the Hall effect, we design and develop the following multi-layer compaction automatic monitoring equipment. 

1. Magnetic detect probe: It consists of 36 sensors to detect the magnetic force from magnetic ring and to simulate the magnetic curve. The equipment can automatically detect the position of magnetic ring at different epoch to calculate the compaction in land subsidence area 
2. IoT translates module: We further adopt the IoT technology to transmit the compaction information to the control center and intelligently monitor the time series of land subsidence. 

• Features: 

1. Sensor matrix include 36 sensors 
2. Automatic monitoring compaction in land subsidence area 
3. Accuracy of measurement is better than 1 mm

Cloud GPS early warning system for surface deformation
The system is established on the Amazon Web Services (AWS). Cloud storage, cloud computing and analysis are utilized fully for the highly automatic procedure of GPS measurements imported, data processing and deformation analysis. The final graphic results are also announced automatically to the Internet for the purpose of early warning. The advantages of cloud application are fully introduced into the system for being applied on the large-scale surveillance. Lastly, not only minimizing the human factors, but the cloud-based system also brings the technology of monitoring engineering to the new stage.

• Features: 

1. Cloud Computing 
2. Global Positioning System 
3. Warning of Surface deformation 

Multi Temporal InSAR, MT-InSAR
Multi temporal InSAR technique has several advantages including (1) high spatial sampling density, (2) high measurement accuracy, and (3) high measurement frequency. 
We use Small Baseline Subset Differential method (one of MT-InSAR methods) with Sentinel-1A images to monitor land subsidence in Choushui River Alluvial Fan and also develop fusion method to combine the results from space-borne (SAR) and terrestrial (leveling) measurements. The fusion result can better represent the overall subsidence pattern and reveal more details of land deformation.  

• ​Features: 

1. High spatial sampling density 
2. High measurement accuracy (10 mm) 
3. High measure frequency (revisiting period: 12 days)
