Supporting examples for my blog post http://kitwallace.tumblr.com/post/77488613583/terrain-modelling-with-srtm-python-numpy-and

The Snowden model uses OS Terrain 50 data as described in http://kitwallace.tumblr.com/post/77585055670/terrain-modeling-in-the-uk

The script extract_os.py extracts height data from an arbitrary lat/long bounding box and 10ksquare is the openscad for a small model - see http://kitwallace.tumblr.com/post/77603439151/terrain-modeling-in-the-uk-2

The lesarcs model was generated directly from a python script from SRTM data
