Barcoding Assets § Assets are Barcoded in the Field
§ All Barcoded Assets are Accurate to within 4-6 inches
§ Data Immediately Available
§ Barcode Data can be Queried
Questar MAPPING Project
Accurate GPS
§ Trimble VRS enables a real-time 4-inch GPS accuracy
through a network of land based reference stations
§ Where VRS is not available
GPS data is post processed
for 4-6 inch accuracy by the
next day
