Weather data (Central Weather Administration)
The forecasts, warnings, weather and rain station observations, radar chart and typhoon information shown in the app and on this website come from the open data platform of Taiwan's Central Weather Administration (CWA), Ministry of Transportation and Communications, provided under the Government Open Data License, version 1. The datasets used are township forecasts, mountain (recreation area) forecasts, weather warnings, automatic weather and rain station observations, the composite radar chart and tropical cyclone (typhoon) information.
akimap.app fetches the data from CWA and only reformats and caches it, without changing the values; the fetch time shown on screen is the time we obtained the data. This is a republication of forecast and observation data, not an official warning or notice issued by CWA; whether typhoon, heavy-rain or other warnings are issued is announced by CWA.

Elevation data (SRTM / Copernicus)
Contours are derived from public-domain SRTM elevation data. Slope shading in some map packs uses Copernicus WorldDEM-30: produced using Copernicus WorldDEM-30 © DLR e.V. 2010-2014 and © Airbus Defence and Space GmbH 2014-2018 provided under COPERNICUS by the European Union and ESA; all rights reserved.
Natural Earth
Some map packs use Natural Earth 10m land polygons for the land and ocean base map; the typhoon map on the website's weather page also uses Natural Earth 50m land data (clipped to East Asia) to draw coastlines. All of it is public domain.
