Topcon Positioning Group launched in 2013 a new web portal, Sitelink3D.net, designed specifically for general construction and engineering companies. The subscription web-based service—accessible via computer, tablet, or smartphone—is a real-time visualization and communications tool that allows users to access jobsite status, create new or update jobsite parameters, and view movement of machines on the job. Primary features and benefits of Sitelink3D include file transfers, messaging, machine tracking, remote support and training, real-time cut/fill mapping, and acquiring and storing real-time survey data. Most machines currently equipped with a Topcon 3D-MC system can be included in the Sitelink3D network by adding the SL-100 radio modem. New Topcon 3D-MC systems can be ordered with the modem pre-installed. Users of Topcon Pocket3D and 3D Office software can also be included in the Sitelink3D network.
