Generate PRIO-GRID Compatible SHDI Variables

Source: R/data_SHDI.R
shdi.Rd

This function processes GlobalDataLab Subnational Human Development Index (SHDI) data and produces a PRIO-GRID–aligned raster for a selected SHDI-related variable. It harmonizes national and subnational observations, resolves missing or empty geometries using geoBoundaries crosswalks, and rasterizes polygon-level values onto the PRIO-GRID using area-weighted aggregation.

Usage

shdi(variable = "shdi", config = pg_current_config())

Arguments

variable

A character string specifying which SHDI-related variable to generate. Supported values include:

  • "shdi" – Subnational Human Development Index

  • "msch" – Mean years of schooling

  • "esch" – Expected years of schooling

  • "lifexp" – Life expectancy at birth

  • "gnic" – Gross national income per capita

Default is "shdi".

Value

A SpatRaster object (from the terra package) aligned to the PRIO-GRID, containing the selected SHDI variable aggregated to grid cells using area-weighted means.

Details

The function may take some time to run due to spatial operations.
