Load the bundled AfSP stratified sample (v0.9.77)

Returns a 120-profile snapshot from AfSP v1.2 stratified by WRB RSG (5 profiles per RSG x 24 RSGs), pre-built so users can run the African WRB benchmark offline without the 35 MB ZIP download.

Usage

load_afsp_sample()

Value

A list with pedons (the PedonRecord objects), pulled_on, source, filter. benchmark_afsp takes this list as it is, or its $pedons.

Details

This is the African analogue of load_wosis_stratified_sample (global WoSIS) and load_kssl_nasis_sample (US KSSL+NASIS).

The snapshot was built in v0.9.77 and holds the AfSP structure codes; since v0.9.312 they are read into words when it is loaded, as load_afsp_pedons reads them.
