Layer: NZLDD_V1_DamSite (0)

Name: NZLDD_V1_DamSite

Display Field: damsiteid

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: The DamSite points signify the location of landslide dams and are situated at the upstream end of each dam. The point position is exactly on the river centreline so that river and catchment metrics can be systematically calculated. For consistency, river centrelines were generated using the 8 m national DEM for New Zealand (LINZ, 2012). For this reason, DamSite points may not always be immediately adjacent to the Dam polygons. There is always one DamSite point for one Dam polygon. For more information visit https://doi.org/10.21420/47GZ-A116.

Layer: NZLDD_V1_Dam (1)

Name: NZLDD_V1_Dam

Display Field: damid

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: The Dam polygons signify the area of landslide debris that blocked the watercourse, forming the landslide dam. Where possible, this includes only the debris that formed the dam while other debris that did not block the watercourse has been mapped separately into the DebrisTrail feature class. Occasionally, the Dam polygon may be representative of the whole landslide deposit. In some instances, the dam no longer exists in the landscape and its extent has been interpreted. The Dam 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 dam. For more information visit https://doi.org/10.21420/47GZ-A116.

Layer: NZLDD_V1_DebrisTrail (3)

Name: NZLDD_V1_DebrisTrail

Display Field: debtrailid

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: The DebrisTrail polygons signify the debris trail of the landslide, defined as the deposit between the Source and Dam, and it can also include debris that did not block the watercourse. Debris trails were not mapped if the deposit extent matched the Dam extent. The DebrisTrail 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 debris trail. For more information visit https://doi.org/10.21420/47GZ-A116.

Layer: NZLDD_V1_Lake (4)

Name: NZLDD_V1_Lake

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.
