Tired of waiting the perfect image with no cloud to show the snow cover? This monthly snow report script is for you.
This code will find where the snow is persistent for the last 30 days (from the chosen date). In order to well represent the land-cover, the script will store each pertinent date in a list and will represent the median value.
As the aim of the script is to represent the snow cover, all the other land-cover are saturated in green in order to easily see the snow.
The limitations are essentially:
Thus, it is possible to make the script working with 90 days in order to have a trimonthly synthesis by changing settings to: “numberOfMonthsToUse = 3”.
