Topographic Anisotropy Figure 10

Figure 10: A) variance measured at single, randomly chosen point along 1 degree intervals for 360 degrees up to 20 km separation distance at ~100 m intervals. Black dots indicate the variance, red line indicates trend of the averaged data. B) Plot similar to A but for all points in the domain, variance values are averaged by direction to compare scaling by orientation. Maximum scaling parameter indicated in red (0.74), minimum indicated in green (0.52), mean indicated in blue. C) Map of Central Otago with the maximum and minimum scaling parameter orientations indicated.
