We started flying the Inspire for a recent project and soon discovered the GPS was lacking in this particular area of tall buildings. So we decided to go back to our first flying tool the Phantom and pulled the GoPro camera and modified it with an extension to view the outer perimeter of the building area. The goal was to find the source of a few well hidden leaks. In addition the tuck pointing on this building was recently completed so the new leaks were a surprise to all involved.
The first image is the jpeg from the raw shot which we enlarged quite a bit.
The second photograph with the red arrow, pinpoints the particular leaks.
All in all the project was a success, the building management team was quite pleased with the quick and economical findings.
