TOPOGRAPHY & BATHYMETRY

This image shows the topography and 
bathymetry of the Circum-Pacific region.  
Blue areas represent elevations below mean 
sea level, and brown areas represent 
elevations above mean sea level.  The 
lightest blue and brown areas represent 
elevations at or around mean sea level.  
The file 'COLORMAP.JPG' (located in 
HAZPAC_ARCVIEW\DATA\IMAGE) contains a 
legend for this image.  The dataset is 
composed of 2-minute resolution data for 
the areas from latitude 72 degrees South 
(-72 degrees) to 70 degrees North, and 5-
minute resolution data north and south of 
those parallels.  The original grid theme 
was downsampled to 2.5-minute by 2.5-
minute resolution before conversion to a 
JPEG image.  The data are from the 
National Geophysical Data Center (1988; 
1997).
