My company Skycell has developed a range of airships which we use of aerial inspection, surveying, photography etc. We do a lot of work in Heritage and particularly stained glass recording in Cathedrals. See our work in York Minster (UK) here.

Other applications include industrial surveying or building inspection.
The vehicles are precise enough to pick out any inch of the Cathedral in precise detail, yet small enough to fit through doors.
We also have a (larger) vehicle that operates outside.
