R Morgenstern, A Wolter, SC Cox, B Lukovic, D Bain, A Sirohi, Z Bruce, K Jones, B Rosser, D Townsend, C Massey. 2023. The New Zealand Landslide Dam Database, v1.0.
The Source polygons signify the source area of the landslide that formed the landslide dam. The Source was delineated using a variety of methods from manual mapping on 1 m resolution LiDAR to unsupervised techniques using remote sensing. The quality of data (e.g., resolution, accuracy, etc.) therefore varies depending on the technique used (linked to the QualityRankings table). This feature class contains attributes that are specific to the landslide source. For more information visit https://doi.org/10.21420/47GZ-A116.
This database has been developed by GNS Science and comprises Version 1.0 of the New Zealand (NZ) Landslide Dam Database (NZLDD). This database contains recent, historic and prehistoric landslide dams in NZ, defined as significant, ephemeral or enduring blockages of a watercourse by a landslide. Version 1.0 contains many catalogued landslide dams, but is not a complete database of all landslide dams that have ever occurred in NZ. A full description of the database is published alongside these data (Morgenstern et al., 2023).
