about

nx_geo_webmerc_gate.nx -- GATE for GEO-019b Web-Mercator tiles. Proves the projection against known slippy-tile quadrants AND that it genuinely DIFFERS from the geodetic GEO-019 grid: z1 (lat 45, lon -90) -> tile (0,0) [NW quadrant] z1 (lat -45, lon 90) -> tile (1,1) [SE quadrant] z2 (lat 60, lon -45) -> Web-Mercator tile_y = 1, while GEODETIC tile_y = 0 -> they DIFFER, confirming this is the Mercator projection (not the plate-carree grid) Evidence -> knowledge/status/geo_webmerc.log (GEOWEBMERCGATE authored=organ ... verdict=GREEN). license_tier: ORIGINAL
