TSA is the only trade association in the UK for geospatial surveying companies. Formed in 1979 by a small and dedicated group of pioneers, it has now grown to over 215 member companies. Council have identified three clear vision statements, building on the original foundations and at the heart of all we do:

- TSA will build you a better business
- Companies with a survey requirement will prefer to use a TSA member
- Every young person should know about geospatial surveying as a career
