Japan GSI Topo Map Layer Plugin

Girai Kaku

Hi Windy community,

I've built a plugin that adds Japan's GIS topographic map (国土地理院地図) as a layer on top of Windy. If you do hiking, trail running, or cycling
in Japan, this is a much more detailed and accurate map than the default outdoor layer.

What it does

At zoom ≥ 10: replaces the default outdoor map with the GSI pale topo map, which shows elevation contours, trails, mountain huts, and terrain detail specific
to Japan
At zoom < 10: Windy's default view is shown unchanged, so weather overlays work normally
Opacity is adjustable from the plugin panel
Works on both desktop and mobile

Tile source
Data comes from 国土地理院 (Geospatial Information Authority of Japan) — the official Japanese government mapping agency. Freely available under their standard
usage terms.

Install URL
https://windy-plugins.com/5026988/windy-plugin-gsi-bvmap/0.1.0/plugin.min.js

Load it via Windy developer mode → paste the URL above, then navigate to windy.com/gsi-bvmap.

Requesting public listing
I'd like to make this available in the Windy plugin store so Japan-based users can find it easily. Happy to answer any questions or make changes if needed.

Thanks!

Hello @girai-kaku !

In your github repo readme you mention that you would like to use vector maps at some point. Starting with the current Windy version (51.2.1), the LeafletGL library's MapLibre core is no longer trimmed and it now has the full MapLibre feature set, including all the vector layer types. It corresponds to roughly MapLibre v5.21. So now you can experiment with vector maps in your plugin if you want :)
