Per-pixel area in hectares

For geographic (lon/lat) grids, area varies with latitude and is computed exactly on the ellipsoid with terra::cellSize(). For projected grids a constant cell area (resolution x resolution) is used. Both are computed block-wise, so large grids are not loaded into memory.

Usage

wapor_pixel_area_ha(x)

Arguments

x

SpatRaster. Template whose geometry defines the area raster.

Value

A SpatRaster of per-pixel area in hectares.
