Google Earth Engine (GEE) - Extracting 250m MOD44W V6 land/water mask products based on the area of the water body year by year (Qinghai Province as an example)

The last article I wrote was about the area extraction based on terrain data for a single scene in 2002. However, it is impossible to check the specific changes of each year based on time series, so this time, in order to meet everyone's needs, I searched for a multi-year water body data. , which is still available from 2000 to 2015, we serve as the subject of this experiment.

Data used this time:

MOD44W.006 Terra Land Water Mask Derived From MODIS and SRTM Yearly Global 250m

Data introduction:

Dataset Availability

2000-01-01T00:00:00 - 2015-1-1

Although the data is available at the time of introduction, the actual research found that the available data is only available until 2015, and the data after 2016 has not been updated.
