Gulf of Maine Water Density Validation Points for Interpolation Accuracy

Gulf of Maine control points used to validate the accuracy of interpolated water density rasters. The dataset was created by NOAA NCEI, with points randomly selected from seasonal and yearly water density measurements at various depths. The data appears to have been last updated in 2004.

Use Cases

• Validate the accuracy of interpolated water density rasters using randomly selected control points.
• Analyze seasonal patterns in water density by referencing the defined fall, winter, spring, and summer bins.
• Assess spatial interpolation error across different depths, as indicated by depth-specific point feature classes like 'ValidationPoints_1997_2004_Fall_0m'.

Strengths

• Validation points were systematically selected using a random selection tool (Hawth's Create Random Selection Tool).
• A defined 25% of each seasonal, yearly, and depth-specific data bin was set aside for validation.

Limitations

• The dataset's temporal coverage and total number of points are unspecified.
• The data is temporally stale, with a last update date of 2004.
• The specific geographic coordinates and spatial distribution of points are not detailed in the description.
