JLS employs only state-of-the-art technology. All traditional field measurements are collected electronically using a TOPCON  9001A 1-second Robotic Total Station with a TOPCON FC2500 Data Collector. This data is then processed using STARNET Least Squares Survey Adjustment Program before being imported into Autodesk Land Desktop 2005 or AutoCAD Civil 3D 2009.

Global Positioning System data is gathered using a TOPCON GRS-1 Network Rover via the Washington State Reference Network. This system provides us the flexiblity to use either Real Time Kinematics or Static GPS observations.
