Quantum Land Design was recently featured in Propeller Aero's Thought Leaders Blog series. The blog post expands on Zach's Tech Talk at Conexpo-Conagg 2020.
Zach discusses a few things you should think about before you jump into the latest drone tech, how you can use the machine control technology you already own and why you need to examine you current workflow to determine how drone data will work with it.
Quality pictures are required to get the best from your drone data. Here is a quick video showing you how to set up the camera on your DJI drone for surveying and mapping missions. Don't have a drone yet? Check out the Quantum Flight Pack. We have another video that will help you set up your mission plans here.
There is a TON of interest throughout the construction industry regarding drones. Drones are a great tool and a low cost way to collect topographic data. Unfortunately, all the hype makes surveying with a drone seem overwhelming, complicated and expensive. At Quantum we subscribe to the K.I.S.S system (Keep, It, Simple, Stupid!) regarding drone data collection. Read to develop an understanding of the basics of drones and data.
The most progressive contractors are moving to 3D modeling for their structural excavations, just like they use a 3D surface model to grade the rest of the project. Quantum's experts take the location and depth information from the Engineer's design to build a 3D model of the structural plans. That 3D model then guides your excavator to dig in the correct location and depth required by the plans, no more, no less. You can use your rover to stakeout locations and depth, too.
Many contractors regularly utilize single point control. It is a great way to use your GPS machine control system for small designs, stockpile calcs or even as an ad hoc laser. Unfortunately, due to the "single point" nature of the process, we have seen it cause problems that could have been avoided. If you need a refresher on how site control works, check out this blog post. It will help you understand why single point control is not used on engineered projects and why you need to be careful using it on yours.
You hired the project Engineer to place your control, you surrounded the site with points and shot in more than five control points. What could go wrong now? A lot, if you don't use some independent checks to verify that your 3D model matches up to the real world.
