gsw_time_series_indicator function

Calculate Global Surface Water Time Series

This function calculates the total area of the global surface water time series data, separated by the following classes:

Format

A function returning a tibble with time series of global surface water data classes.

calc_gsw_time_series()

Details

• No Observation: It was not possible to determine whether a pixel was water (this may be the case for frozen areas or during the polar night in extreme latitudes).
• Permanent Water: Water was detected in twelve months per year or in a combination of permanent and no observation.
• Seasonal Water: Water and no water was detected.
• No Water: No Water was detected.

The required resources for this indicator are:

• gsw_time_series_resource
