Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description:

This shapefile was used to control the extent of the delivered clipped topobathymetric model and avoid false triangulation across areas in the water with no returns. Unmapped areas/Voids were identified by triangulating bathymetric bottom points with an edge length maximum of 4.56 meters. This was done to ensure that all areas of no returns greater than 9 m^2 were identified. The horizontal datum for this dataset is NAD83 (2011), the vertical datum is NAVD88, Geoid 12B, and the data is projected in UTM Zone 11N. Units are in Meters. Quantum Spatial collected the John Day River NIR LiDAR data for Tetra Tech, Inc. on 11/12/15, 11/13/15, 11/14/15, 07/16/16 and 07/20/16. The Bathymetric LiDAR was collected on 07/15/16, 07/16/16, 07/17/16, and 07/20/16.
