gsw_seasonality: Calculate Global Surface Water (GSW) Seasonality

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

Calculate Global Surface Water (GSW) Seasonality

Description

GSW seasonality describes the intra-annual distribution of surface water for each pixel. The raster files have integer cell values between [0, 12], indicating how many months per year the pixel was classified as water.

Usage

calc_gsw_seasonality()

Details

The pixel values are aggregated using method provided via the stats parameter.

The required resources for this indicator are:

• global_surface_water_seasonality

Value

A function that returns an indicator tibble with seasonality categories as variables and corresponding areas (in ha) as value.
