About these files
Mapping features need test data that is recognisably correct when drawn. These GeoJSON samples place features around well-known cities, so a swapped coordinate or a projection error is obvious at a glance.
Larger files hold thousands of features and are suited to testing clustering, tiling and rendering performance.
