About us
The association was formed in 1979 to give a focus for private sector businesses in land and hydrographic survey. It is important to realise, however, that it is not a regulatory body.
The role of TSA is to promote best practice amongst its members, provide a forum for members for discussion, debate and continuing professional development and, to the wider audience such as engineers and architects, provide guidance on new methods and techniques and a list of suitably qualified and experienced companies.
