11.C. Elevation Data File Sizes, Regional Extent, and Statistics

Table 3 (below) lists the name, latitude and longitude extent, elevation statistics, and file sizes for each tile. There is no overlap among the tiles so the global data set may be assembled by abutting the adjacent tiles.

* Note: This "minimum" shows the minimum elevation on land. Every tile contains values of -500 for oceans, with no values between -500 and the minimum value for land noted here.

** Note: This tile contains the AUSLIG/NGDC DEM, and is the only GLOBE Version 1.0 tile containing enhanced/restricted B.A.D. data.

Also NOTE: If using a UNIX workstation, Apple Macintosh or some other computer, your file names may appear in lower case after reading files from the CD-ROMs or Web site.
