If you are a teacher and would like someone to come and talk to your students about surveying, then please contact us at: office@tsa-uk.org.uk
One of our members will be happy to come to the school and tell the students about surveying in general and also give a demonstration using some basic equipment. This equipment can be left with you for a period to enable the students to really get to grips with it.
You will find some really useful stuff on the Mapzone site produced by the Ordnance Survey.
