Attribute_Accuracy_Report:
The bathymetry and coastline data and other line data were merged and edited in ARC/INFO, which caused some edge-matching problems among the data sets. The new USGS-KORDI survey bathymetry data were desampled to a 250-m spacing. A buffer zone 4500 m to either side of the new data was used to mask out the underlying two-minute data. The resulting data sets were combined to construct a surface according to the triangular irregular network (TIN) model supported by ARC/INFO. The data were gridded on 1000-m grid cells with a smoothing (quintic) option. Contours were extracted at 200-m intervals. Final map was compiled and edited in Adobe Illustrator, v. 8.0.1.

Process_Description:
Extracted shapefiles for 200-m contours extracted from Marshall Islands grid.

Removed depression contours from southern Kwajalien per inspection of latest version of ETOPO2 data <http://www.ngdc.noaa.gov/mgg/fliers/06mgg01.html>. Parent grid unchanged.
