Water storage anomalies can be detected by satellite gravimeter. The measured mass change thus water (fluid) flows in groundwater system owing to gravity anomalies is then converted into equivalent thickness (height) per square unit using the density of refresh water. It is very useful to know how groundwater storing in such as basin varies with respect to time especially season change. The variation of groundwater is directly associated with vegetation. Accordingly, it is much meaningful to locate data of water storage anomalies and refined data of vegetation from LiDAR together (see Figure 9 to 12).

On the other hand, as well known, gravitational force can be resolved into vertical and horizontal component. Thereby, the data of water storage anomalies are able to forecast the overall flow direct in groundwater system, but detailed information may have to rely on the measurement of satellite altimeter.
