Survey of Palmerston North, New Zealand

This was the pilot's first circle survey project. She was given a short tutorial on the ground. This included showing the WaldoFCS interface, how to approach a new circle path and what the tolerances were. It was a near perfect flight. The weather conditions were not brilliant. There were high winds and it was overcast with low-level cloud. It had been raining near the site.

 

Processing

This was processed using Skyline Photomesh in a less-than-ideal setup. Three low-powered machines were connected via WiFi to do the work. The combination of a low-powered mini deskop machine, an ultrabook laptop and a Surface Pro laptop meant this wasn't the fastest build ever. Still it got the project completed in time to show a client. The more fusers you add to a Photomesh job, the quicker it will produce the results.

Notes

  • All datasets are in New Zealand Transverse Mercator (NZTM2000)
  • Watch out for the crazy section of data in the North East of the project that was outside of the circle path, hence the warping.
  • Take a look at the viewshed tools in the Kit. We added a 'proposed' building so you can see the impact it makes.
