We have used Ordnance Survey 3D data which is now freely available, to construct a section on the Snowdonian Mountain range. We have made the water level interactive so the user can enter a height and the water level will rise to that position. This is just one of the many uses the free OS data can be put to. It is extremely accurate and can be used for any geographical processes that require this level of detail. It allows us to show syllabus related content in actual environments. This is an example of the multimedia assets that can be integrated into the system. This is only a sample of the content available.
