Arnis, developed by Louis Erbkamm, is an open-source project that allows users to transform real-world locations into Minecraft blocks and maps. Initially limited to the Java edition, it has been updated to support the Bedrock Edition, enabling integration across various devices. The tool has improved elevation generation using NASA data, allowing users to visualize landscapes like the Alps and Himalayas, as well as explore a map of the Moon. The accuracy of the generated landscapes has been recognized for use in research studies on flood mitigation education. The project's advancements are attributed to a dedicated community that supports its development.
