New “survey grade” GPS equipment
On 06, Dec 2016 | In Field mapping, GPS | By Eric Compas
For many of our mapping projects and contracts, from mapping storm sewers to electrical networks, we’ve needed more accuracy than our “resource grade” Trimble GPS units can provide. This has been particularly true for our UAV imagery. Since we’re producing images with resolution of between 1-5 cm, we need ground control that’s as accurate or better than this resolution. Our Trimble units under ideal conditions can provide 15-30 cm horizontal accuracy — not good enough. Plus, we’re hearing more about local government units purchasing higher-accuracy devices which our students need exposure to. Read more…
