The Survey Association
The Survey Association, known generally as TSA, is the trade body for commercial survey companies in the UK. The association was formed in 1979 to give a focus for private sector businesses in land and hydrographic survey. 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. Today, the association has over 170 companies in membership as full, associate, supplier, affiliate or academic members directly involved in the survey business.
