Guidelines for access to aerial imagery
Due to the nature of aerial imagery and the market for its supply, a VAR’s intended usage must be acceptable to Landgate and specified within a licence before access and pricing is provided.
- Generally, Landgate will allow access to imagery where it will not be used as the primary focus of a derived product. Where the focal point of a VAR’s product is in providing functionality, information or a solution to a problem and aerial imagery is merely providing a supplementary visual reference/backdrop, it will be considered favourably.
- Where the selling point of a VAR’s product is the actual aerial imagery, with added functionality considered secondary or an enhancement to the imagery, then Landgate will not provide imagery access.
- Where a VAR creates a product that will have users frequently consuming large amounts of imagery (within the SLIP environment), resulting in degraded performance for other subscribers. In these instances, Landgate may look to provide the imagery via an alternative channel.
The acceptance of a value added reseller application for imagery will be case by case at Landgate’s discretion.
