convert os mas to stl

1. OS2STL

2. Project Description

Our program takes a given post code or OS
map reference to create a .STL file of the
area which can then be sent to a 3d printer.

In this way you can easily visualise large
areas of terrain and make decisions regarding
development from this.

All of our code is available on github at:
github.com/RobertABT/heightmapwebapp

Live demo os2stl.co.uk

4. Why?

A year ago I was looking around at 3d printing
areas of land to help plan a radio broadband
link which required line of sight.

Scale models of this sort could be used by
anyone from model hobbyists, to tabletop
gamers to property developers.

5. Existing solutions

There are some existing tools and methods to
create .stl files from given areas but they are
either expensive and closed source, fiddly or
very difficult to implement.

(For loading terrain data into Openfoam there
is an 18 page pdf document!)

6. The data

Our project uses Ordnance Survey Terrain50
data files (which are downloadable from their
website) to generate the .stl files

and-government/products/terrain-50.html

It also uses an open source API to convert
post codes to OS grid references.

7. The code

The web app uses a mix of Python (which
does the core processing) along with
Javascript and HTML (to display the webpage
and the .STL file preview)
