Digital elevation data
The site is in a farming region in gently rolling granitic terrain, with some incisions and breakaways,
and with maximum topographic relief of approximately 75 m. A 1m-cell digital elevation model over the
‘core’ AGG area (Figure 4) was provided by Fugro Spatial Solutions from an airborne laser scanning
(LiDAR) survey flown in October 2009. The point elevations have an estimated horizontal accuracy of
0.16 m and an estimated vertical accuracy of 0.05 m.
