( Here's a tutorial for doing this in Blender.) Import the resulting image as a displacement map in a 3D application to generate a 3D model of the terrain.(You may need to right-click the image to do this.) Click 'export' to open the current view as an image in a new tab - then 'Save As' to save the image to disk.Uncheck 'auto-expose' to set min and max height levels manually.Here's a blog post about this tool, with more explanations and examples! The result is a grayscale heightmap, suitable for use as a displacement map in 3D applications. This is an elevation data browser, which 'auto-exposes' the display so that the highest and lowest visible elevations are white and black.
