The Washington County Engineer's Office is getting a new GPS system. County Engineer David Patterson says this will replace an older system they have which is about 10 years old. Patterson says this new system is not like the one you by at a department or the Garman GPS units, this is much more accurate, with as he puts it golf ball size accuracy. The new system will cost $22,500 and work with a new GPS network the state is activating. Patterson says the equipment is instrumental in their work.
