Need help making a map

first off, i’m a n00b at this stuff but I thought I would give this a shot. I am trying to make a map of Europe for my upcoming grand strategy game using the terrain tool but I am finding it tedious and uncooperative : (. I was wondering if there was a faster and easier way of making accurate terrains in Unity. Thanks in advance.

You can use height map (an image) to automatically generate terrain with that map, like in any 3D software.

Try the searching for European Heightmaps on google there must be something. Then add detail in Unity.
