Abstract
The purpose of the Tenterfield capture was to firstly test all procedures associated with Lands LiDAR program on a larger scale, more similar to what we believe to be a standard sized job. The purpose also extends to providing a usable surface model of the entire catchment along with a high point density focus area over the urban area of Tenterfield.

This job was planned due to a requirement for high accuracy aerial photography to be used as part of a cadastral adjustment program. The high quality laser derived surface means that there would be minimal distortion on the part of the imagery and so it would suit the purpose well. The job was extended beyond the immediate town extents as the council was also interested in floodplain mapping and cadastral adjustment in the surrounds.
