Accuracy specifications, control and the deliverables a survey contract owes
A survey contract is defined by its accuracy statement, and everything else follows from it. The tender should state the required positional accuracy, the coordinate reference system and vertical datum, the ground sample distance for imagery, and the point density for laser scanning, because those parameters decide the equipment, the flying or occupation time and therefore the price. A bid quoted against an unstated accuracy is not comparable with anything, and buyers who leave it out receive a spread of prices that tells them nothing.
Control and verification are what separate a survey from a collection of measurements. Ground control points established and observed against a recognised network, independent check points not used in the adjustment, and a reported accuracy assessment against those checks are the evidence that the specification was met. For airborne and satellite work, weather windows, airspace permissions and in some jurisdictions restrictions on aerial imagery are genuine programme risks that a realistic bid acknowledges rather than assumes away.
Deliverables and rights need to be specified item by item. Point clouds, orthoimagery, digital terrain and surface models, vector features captured to a defined schema and the metadata describing all of it come in formats that determine whether the buyer can actually use them, and the licence determines whether it can publish or share them. Public buyers increasingly require full rights and open formats so the data can be reused across the organisation, and they specify the metadata standard, because a survey nobody can find or interpret in five years has been bought twice.
This section describes how this category is bought generally, across the public buyers that publish it. The figures elsewhere on this page are measured for this market alone.
