What Users Are Saying? 

"This is the solution I have been looking for since my GeoStar/MultiPlane days, over 15 years ago.
Thanks guys.
Arnie Hinkson, Hinkson Land Tech, NE, USA

"I was frankly amazed!! I had expected to see upwards of 100 thousand cubic metres to sort this job out. OptiSurface came in at 27 thousand cubic metres, saving my client many tens of thousands of dollars and keeping my company ahead of the competition and profitable. Thanks again.”
Neil Garson, Garson & Company, Australia

"I am truly impressed.  It scares me a little because I thought more soil would need to be moved.  
Plus, it can not be that easy."

Rick Greene, Precision Manager, MFA, USA

"WOW!! I believe this is going to herald a new future in landforming."
Dave Davies, Mechanized Ag. Consultants L.L.C., Africa

“OptiSurface is great software which saves me a lot of time to plan and in the field saves a lot of money and time to make my land an optimum shape.” 
Donald Lambert, Farmer, Canada

"The software is awesome, particularly now that I’m figuring out how the design zones work. Your support center with the knowledge base has been really helpful. Thanks for all the support!
Tage Stam, Geotrim, Finland

"OptiSurface Designer delivers an 80% reduction in design time but more significantly up to a 90% reduction in earthworks."
Lew Brandon, BMS LaserSat, Australia.

  “OptiSurface designs are going great.
Our clients love the ponding, and runoff analysis features. At the moment we are busy with the earthworks for an 
OptiSurface design and its going great." 
Corriee De Boer, JD Hoffman Earthmoving, Africa

"We've had about 12" of rain and water has been flowing through that paddock we OptiSurfaced, but it is draining brilliantly. You can't believe how much better it is!"
Wade Bidstrup, Aloe Farming Co, Australia

"I am really impressed with your software. It seems to me the only way forward for land grading in agriculture. Well done."
Tony Crowley, Independent Agricultural Resources Pty Ltd, Australia 

"Algorithms are the best in the business, no question. Bigger earthworks savings."
Andrew Sevil, "Whyenbah" Farm, Australia 

 "OptiSurface greatly reduces my farm development costs and just as importantly minimises topsoil distrubance."
David Cox, Davco Farming, Australia

"You can't change the way people think, all you can do is give them a tool, the use of which will change their thinking."

Our Story

We believe good surface drainage is crucial to achieving a highly productive and efficient farming operation.  

We farm and fully understand the benefits of precision surface drainage of agricultural fields. We were one of the first growers in the world to use laser levelling in sugarcane production starting back in the 1970s. It was a tremendous leap in technology enabling the transformation of basic land into highly efficient and very productive farming operations. However, the problem with laser levelling and its corresponding multiple plane designs is that we often see more than 4 times the earthworks compared to the new technology. Apart from the much larger earthmoving cost that this involves, it also scalps a lot more topsoil which can have significant impacts on crop yields for decades. We continue to develop land for sugarcane farming and saw the opportunity that GPS machine control offered in solving the limitations of laser levelling. So over ten years ago, we set about coming up with a system that took full advantage of this new technology. That is what we call Optimum Surface Landforming™ or OptiSurface™.
