Display Field: lakeid

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: The Lake polygons signify the known or inferred area inundated by landslide-dammed lakes. In many instances the lake no longer exists in the landscape and its extent was inferred based on geomorphic features such as sedimentary plains, wetlands, and deltas. If no obvious signs of a past lake exist for a particular case study, a lake was not mapped. Where the landslide-dammed lakes still exist today (typically for large, enduring dams), the current lake extent was taken from the LINZ topographic 1:50,000 scale mapping (LINZ, 2020a, 2020b). These are likely not the initial or maximum lake extents, particularly for old dams. The Lake was delineated using a variety of methods from manual mapping on 1 m resolution LiDAR to using the LINZ 1:50,000 scale map data. 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-dammed lake. For more information visit https://doi.org/10.21420/47GZ-A116.
