Station counts describe packaged catalogue entries, not continuous data coverage or unique physical sites across providers. South Africa supports catalogue discovery only. A station on the map need not have observations for a requested quantity or period. See provider capabilities.
Markers use catalogue coordinates. Unknown-CRS coordinates are displayed as if they used EPSG:4326; that display assumption does not establish their reference system. Use the map for exploration, not coordinate certification.
