How can I cover the terrain with one big satellite imagery which are complete overlap?

as the picture shows, the terrain and the satellite map is rectangle, the material made by satellite map is square and multipled, and how can I make it overlap?

as you know the size and position of your terrain, you will just have to configure the size and offset parameters to position your image.

I tried this material, but the shape of it is still square, which can’t stretch to fit the rectangle terrain.
