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.
