What's new with LINZ Basemaps
summary
LINZ Basemaps serves WMTS/XYZ tiles combining Sentinel‑2 at low zooms with 30 cm rural aerial imagery and a vector Topo50 service, and has served around 5 billion tiles with 140 TB transferred. New additions: 223 scanned aerial surveys (now georeferenced and ortho-rectified) and a public AWS Open Data bucket of the entire aerial archive as Cloud Optimized GeoTIFFs used as the live source for the basemap. Stack/STAC metadata, a COG driver funded upstream, Sharp for rendering, and open source builds on GitHub enable reproducible delivery and upcoming national elevation services.
