Supplemental Information |
The vertical datum for the source bathymetric data was generally Mean Lower Low Water (MLLW), Lower Low Water Large Tide (LLWLT), Mean Sea Level (MSL), or assumed MSL The differences between these datums are less than the vertical accuracy of the CRM, so you can assign Mean Sea Level to this DEM if you like, just recognize that the elevation values may not be as accurate as you might like or need. Assume a
vertical accuracy no better than 1 meter for any elevation values. Because of its relatively large cell size (3 arc-seconds or roughly 90 m), no effort was made to establish a common vertical datum as the uncertainty in the elevation value of each cell exceeds the differences between vertical datums (typically sub-meter). |
Purpose | Developed for the Pacific Marine Environmental Laboratory (PMEL), NOAA Center for Tsunami Research program in support of NOAA's tsunami forecasting and warning efforts. |
