Leaflet.MML-layers

National Land Survey of Finland (MML) free maps on Leaflet.

Predefined Leafler tile layer settings for kartat.kapsi.fi TMS service. Supports both EPSG:900913 & EPSG:3067 layers. If you want to use EPSG:3067 layers you must include Proj4Leaflet

WMTS layers. After 9.12.2020 using these layers requires an (API key)[https://www.maanmittauslaitos.fi/rajapinnat/api-avaimen-ohje]. API key can be provided as a parameter or using basic auth. Proj4Leaflet must be loaded to use WMTS layers.

Since version 1.1.0 it's possible to use WMTS layers from MML.

var map = new L.map("map", {
  crs: L.TileLayer.MML.get3067Proj()
}).setView([61, 25], 6);

L.tileLayer.mml_wmts({ layer: "maastokartta", apiKey: 'key' }).addTo(map);
