“The integration of CHPS with GIS has allowed me to work more closely with Harvest Supervisors to immediately see the effect of changing machines or tailhold locations on payload and to produce legible maps which can then be shared with the contractor.”

Megan Costello,
Harvest Engineer, Ernslaw One, New Zealand

“Having the CHPS program connected to our GIS system makes everything easier. I don't need to import anything, I can just work within the maps I have created. More importantly I can give contractors maps with profiles on them in a format they are used to.”

Patrick Bethel,
Harvest Planner, Hikurangi Forest Farms, New Zealand

“Our students have picked CHPS up really easily (always a good sign of excellent software), and it is a dream compared with other cable harvesting software: so intuitive, seamless integration with ArcGIS, just really great! The students really love it. We will keep having fun with CHPS!”

James Broadley,
Forest Management Tutor at Waiariki Institute of Technology, Rotorua, New Zealand

“GBS approached me to develop and test a set of payload calculations for use within their CHPS product. I based this work on similar calculations to those used within LoggerPC and SkylineXL. These calculations are supported by a large body of published research material, much of it from the Pacific Northwest region of USA, and are considered to be the industry standard. I provided GBS with a set of well tested calculations that they could integrate into CHPS. Using a rigid-link assumption the calculations model full and partial suspension, uphill and downhill yarding, clamping and non-clamping carriages, for four types of yarding systems (live, standing, running and multispan skylines). I am confident that the calculations used within CHPS are robust and represent the best available at this time.”
