In order to detect outliers in the measurements, a high pass filter was implemented.
Autocorrelation analysis of GPS time series was also performed to validate the
presence of white and coloured noises in the GPS measurements.
The main problems encountered during field work include: power supply
problems and fluctuation in Internet services. There is a great concern for power
supply because a typical landslide site may be located in remote areas where
access to the electric network is not readily available. The fluctuation in Internet
services was a big concern as this may have contributed to a high latency rate in
the streaming of the data.
