3d Printing Topographical Models
There are a variety of websites that provide the ability to create a 3d-printable (.stl) topographical model of any region you'd like. Different sites have varying levels of resolution and cover different areas of the world, below is a list of useful programs with brief descriptions of their abilities and differences.
The advantage of Terrain2STL is that it is global, meaning you can create a model of topographical features from anywhere in the world, although the resolution is not quite a high as some of the other websites.
This website includes a tutorial for printing terrain models including models using data from LIDAR systems, which is usually very high-resolution measurements.
