Case Studies for OS Net Free Services

This section contains a selection of case studies utilizing the free National GPS Network services.

• Low-cost GPS surveying for amateur field studies groups.
  Several amateur history groups are engaged in exploring and recording the visible sites and alignments of landscape features for possible professional investigation at a later date.
• Archaeological survey using GPS at RCAHMS.
  The Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS) undertakes an archaeological recording and mapping programme across the whole of Scotland, targeting areas on a strategic basis.
• Assessment of the hydrological condition of raised peat bog systems using differential GPS to acquire high quality topographic data.
  Dennis Sinnott is part of a small team working on the conservation of wetlands. An important element of this work involves developing the use of GPS to help evaluate past damage to the self-sustaining hydrology of raised peat bogs.
• Monitoring the movement of St. Catherine's Point Lighthouse using the Ordnance Survey GPS Network.
  In the autumn of 2000, the active network station at Saint Catherine's Point (SCP1) on the Isle of Wight began to gradually shift south towards the English Channel from its original coordinate position.
