RIAI Tessera

A survey flight in,
a condition map out

Runways, taxiways, aprons and road pavement. One aerial survey becomes a tiled condition map: every crack found and measured, every tile scored, the whole surface ranked so you know which sections to resurface first.

A survey pass over a runway. This is the input: nadir imagery at a fixed altitude, flown in overlapping strips.

From Flight To Plan

One pass, then the whole surface

The survey is cut into tiles, each one scored on its own, then reassembled into a picture of the pavement you can plan against.

The whole surface, zoned and scored

The survey area is split into zones that follow how the pavement is actually managed. Each zone carries its own condition index and crack count, so a single view answers which part of the airfield needs attention.

Zone breakdown Overall PCI Crack totals
Tessera survey view: nine colour-coded zones overlaid on aerial imagery of an airfield, with overall condition index, tile count and crack count.

Condition, tile by tile

Zoom into a zone and every tile is coloured by its condition index, from good through to poor. The deterioration shows up as a pattern across the surface rather than a list of coordinates, which is how resurfacing actually gets scoped.

Every crack found, traced and measured

Open a tile and every crack is traced on the imagery, down to the hairline ones a walking survey would miss, each with its length in metres and a severity of its own. The condition score for that tile is built from those measurements, so the number is always traceable back to what was actually seen.
