Data Attribution

Nwiro’s landscape generation builds terrain from open elevation (DEM) datasets. The credits below cover the data sources behind that terrain. If you distribute a project that uses terrain generated with Nwiro, include the relevant attribution from this page in your project’s credits.

The same notices ship with the plugin in THIRD-PARTY-NOTICES.txt, and the canonical web version lives at nwiro.ai/attribution .
