As others have said... No the GPS isn't a suitable surveying instrument

The Pocket Transit

This is one inexpensive and used properly accurate device

It can be mounted on a tripod which IMO is essential for this type of 
surveying

There are many out of copyright books that would cover what you need to 
know
