WGS 84 / Web Mercator tile scale set definition

LINZ’s map tile services are available in the popular Web Mercator coordinate reference system.

Spherical/Web Mercator (EPSG:3857) is the projected coordinate system commonly used for web mapping and in services such as Google Maps and OpenStreetMap (OSM). It supports map tile services that have worldwide coverage, or that need to interact with third party tile services without needing you to reproject or scale.

To support interoperability of LDS tile services, with other mapping services, such as OSM and Google Maps, LINZ has adopted the well-known tile scale set for this coordinate reference system.

This tile set has global coverage, including New Zealand and the offshore islands.

Specification

This specification is based on Annex E of Open Geospatial Consortium’s Web Map Tile Service Standard.

Please note:

  • WGS 84 / Web Mercator (EPSG:3857) is sometimes referred to as Google Web Mercator with a reference code of EPSG:900913.
  • The map tile you see in the LDS website map preview window are defined using the WGS 84/ Web Mercator tile scale set.
  • LDS supports zoom levels 19-21 which are not defined as part of the OGC specification. This is to allow zooming into smaller scales.
