Rees River, New Zealand - Geomorphic Change Detection - Example Dataset

A simple Example GCD Dataset illustrating topographic change detection on a long (31 km) dataset. Great for learning about analyses with DEMs produced from a hybrid of survey types. Used in Multi-Method Error Estimation Tutorial and Morphological Approach Tutorial. This is part of the dataset from:
