gsw_time_series_indicator: Calculate Global Surface Water Time Series

In mapme-initiative/mapme.biodiversity: Efficient Monitoring of Global Biodiversity Portfolios

Calculate Global Surface Water Time Series

Description

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

Usage

calc_gsw_time_series()

Format

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

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
