- 01Kestryl Obstruction Index
- Kestryl's quarterly measure of physical obstruction across the world's outdoor media inventory: what gets between the panel and the audience, published by market.
- 02Campaign Check
- Kestryl's product for advertisers and agencies: a reviewed, dated physical-visibility result for every panel on a campaign list, with a Keep, Review or Replace decision per panel.
- 03Network Program
- Kestryl's recurring product for media owners: every assessed panel carries a current, evidence-backed visibility status, surveyed twice yearly and monitored between passes, with ranked maintenance priorities and permit pathways.
- 04Mapped or screened panel
- A panel Kestryl has located and assessed from aerial capture: location, format, height, facing bearing and sightline risk. Deep-scored panel faces additionally carry a ray-cast obstruction score and growth forecast, reviewed before publication.
- 05Obstruction score
- The percentage of a panel face hidden from the driver's approach sightline, computed from segmented aerial and street-level imagery.
- 06Occlusion
- Any physical interruption between the viewer and the panel face: most commonly vegetation, occasionally structures or signage.
- 07Sightline
- The unbroken line between a moving viewer's position and the panel face across the approach path.
- 08Approach window
- The stretch of road from which a panel is both visible and readable, given distance, angle and travel speed.
- 09Classic inventory
- Static (non-digital) out-of-home panels: bulletins, posters and wallscapes.
- 10Visibility decay
- The rate at which a panel's obstruction score worsens between capture cycles, used to forecast when a site will cross the obstruction threshold.
- 11Occlusion horizon
- The forecast month when a growing tree is expected to cross a panel face, computed from species growth curves over a zero-to-60-month window.
- 12Growth-weighted canopy
- A canopy footprint weighted by its species growth curve: how big this tree will be, not just how big it is today.
- 13Sight cone
- The cone either side of a panel's facing bearing, cast across its approach path, inside which obstruction is measured.
- 14Dual-scorer
- Two independent scoring methods, angular and ray-cast, run for every panel face and reconciled against street-level imagery before a score is published.
- 15Planning overlay
- Local planning controls attached to each tree in Australian coverage, such as vegetation protection, significant landscape and heritage overlays. Overlay status determines whether pruning a tree needs a permit, and how long that takes.
