Description

Title
Corner Inlet Depth Contour Lines at 1:25,000 
Alternate title
BATHYMETRY_CORNER_INLET_ARC 
Resource Type
Dataset 
Purpose
BATHYMETRY_CORNER_INLET_ARC is a 1:25 000 layer used for depth analysis. This layer will serve as a Digital Terrain Model (DTM) until more depth data can be obtained from which DTMs can be generated using automated techniques. Common uses for depth zone information include comparative analysis with fisheries catch data and representing the movement of commercial species in three dimensions. The depth information within this layer should not be used for navigation purposes.

Supplemental Information
History: This layer replaced DEPTH25_ARC in March 2010 Relationship to other Datasets: The DEPTH25 layer draws on information stored within the COAST25 layer. The landward boundary is the 1:25,000 coastal trace. The coastal trace is subject to change especially in areas subject to erosion or mass movement of coastal sediments. Current Design Issues: All bathymetric information is collected as point features or spot depths. Isobaths are interpreted either by visual manual methods or by automated techniques. As more data becomes available the positional accuracy of isobaths should be revised. Each acquisition of depth information needs to be documented and assessed before it is incorporated in the layer. Future Design Issues: This layer is a base line data set and future design considerations will be limited. Related Documents: None

There has been no assessment of attribute accuracy. 
 
Positional Accuracy
Comments
For the source data (Hydrographic Survey Office maps), horizontal accuracy is 10m to 100m of well defined points, and vertical accuracy is 10cm to 100cm in elevation. For the digital data, any departure between the digital and source material (measured between centre lines) will not exceed 1mm at the map scale of 1:25,000. Determination: Positional accuracy is only an estimate and has not been subject to any test. The depth information within this layer should not be used for navigation purposes.
