leaflet-mml-layers v3.0.1

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.
