Why was it made?

TerrasEdit was created to semi automate the building process of the Minecraft BuildTheEarth project, by allowing builders to draw outlines that span huge areas.

This saves a lot of time and allows builders to focus more on detailing their builds than manually referencing map sources to draw the outlines, which can take hours. This also means non minecrafters could also contribute by helping to outline from a top down perspective.

For most countries, copying and pasting latlng coordinates is still needed, while BTE teams that include Singapore, Taiwan or Hong Kong can use their own sourced satellite map tiles to draw on.
