Tshydro tool

One 、 Tool is introduced
https://github.com/cavios/tshydro
tshydro：R package that estimates water level time series from satellite altimetry data.

The core of the package is a state-space model with a mixture distribution to account for erroneous observations.

Model input ：
height
track
time

Model output ：
time
water level
water level sd

The dynamic model is mainly used to deal with all the water levels of the lake , Constructing water level time series of lakes .

Dynamic model refers to the combination of error mixed model and spatial state model , It includes two parts: process model and observation model .

The process model is used to represent the relationship between the real water levels ; The observation model is used to reflect the relationship between the actual observed water level and the real water level .
Two 、 Use steps
（1） Download Kit tshydro, Refer to https://blog.csdn.net/qq_32649321/article/details/120038222
test tshydro Is the package installed successfully , Input at the console ：library(tsHydro)

Indicates successful installation ！
（2） Load test data , verification tshydro Model
