so i need the 'how to get shuttle radar data' thing into grey scale

resize the canvas
when you export, you'll have to use finder to rename extension to .raw
in unity - game object - 3d object - terrain - then in the inspector hit the gear wheel then you can import. important to have the x, y, z as in the image. you can change the x and z, this'll make the landscape bigger. leave y alone. make sure the import values are what you originally resized.
