In-situ soil moisture sensing: Optimal sensor placement and field estimation

  title={In-situ soil moisture sensing: Optimal sensor placement and field estimation},
  author={Xiaopei Wu and Mingyan Liu and Yue Wu},
We study the problem of optimal sensor placement in the context of soil moisture sensing. We show that the soil moisture data possesses some unique features that can be used together with the commonly used Gaussian assumption to construct more scalable, robust, and better performing placement algorithms. Specifically, there exists a coarse-grained monotonic ordering of locations in their soil moisture level over time, both in terms of its first and second moments, a feature much more stable… CONTINUE READING
