Smith、Paolo Paron、James S. Griffiths担任主编的《地球表面过程进展（Developments in Earth Surface Processes）》，由爱思唯尔（Elsevier）出版，第15卷，第507-532页，国际标准刊号（ISSN）0928-2025，数字对象标识符（DOI）：10.1016/B978-0-444-53446-0.00020-3。本数据集的采样区域为新西兰皇后镇附近一段2千米长的辫状河道，包含两次激光雷达（Light Detection and Ranging, LiDAR）测量数据，空间分辨率为0.5米/像元。支持完整数据集与仅形态学数据集两种下载选项，数据集包含用于实操练习的原始数据，以及可直接打开的完整*.gcd项目文件。
