Abstract:

GLOBE is a project to develop the best available 30-arc-second (nominally 1 kilometer) global digital elevation data set.  This version of GLOBE contains data from 11 sources, and 17 combinations of source and lineage.  It continues much in the tradition of the National Geophysical Data Center's TerrainBase (FGDC 1090), as TerrainBase served as a generally lower-resolution prototype of GLOBE data management and compilation techniques. The GLOBE mosaic has been compiled onto CD-ROMs for the international user community.  It is also available from the World Wide Web (linked from the online linkage noted above and anonymous ftp.        Improvements to the global model are anticipated, as appropriate data and/or methods are made available.  In addition, individual contributions to GLOBE (several areas have more than one candididate) should become available at the same website. GLOBE may be used for technology development, such as helping plan infrastructure for cellular communications networks, other public works, satellite data processing, and environmental monitoring and analysis.  GLOBE prototypes (and probably GLOBE itself after its release) has been used to help develop terrain avoidance systems for aircraft.  In all cases, GLOBE data should be treated as any potentially useful but guaranteed imperfect data set. Mission- or life-critical applications should consider the documented arti- facts, as well as likely undocumented imperfections, in the data.

Data Quality Information:

Attribute Accuracy:

Attribute Accuracy Report:

Some of the methods used to measure elevation do not actually measure that of the ground surface. See GLOBE documentation (KGRD 34).

Quantitative Attribute Accuracy Assessment:

Attribute Accuracy Value:

variable may range +/- 10 to +/- 250 meters or more

Attribute Accuracy Explanation:

statistical and histogram analysis

Logical Consistency Report:

GLOBE documentation (KGRD 34) discusses logical consistency implicitly in its quality control & accuracy assessments. Adjacent data files have no gaps between themselves. A few land areas of 30 arc-seconds in size may be missing. Most smaller areas are missing. Bathymetry is not included in GLOBE Version 1.0 (See NGDC's TerrainBase or ETOPO5 for lower-resolution Bathymetric data. GLOBE Version 2.0 may include bathymetric data.)

Completeness Report:

Unknown

Positional Accuracy:

Horizontal Positional Accuracy:

Horizontal Positional Accuracy Report:

arc-seconds of latitude and longitude

Quantitative Horizontal Positional Accuracy Assessment:

Horizontal Positional Accuracy Value:

18.000000

Horizontal Positional Accuracy Explanation:

Few elevation values should be more than about 18 arc-seconds from their implied location in the 30 arc-second grid.

Vertical Positional Accuracy:

Vertical Positional Accuracy Report:

Vertical accuracy varies by source materials used in GLOBE. Values may range from 10 meters to 250 meters (and in rare cases, to over 500 meters in elevation). In the field (below) vertical position accuracy value, we have arbitrarily assigned the number

Quantitative Vertical Positional Accuracy Assessment:

Vertical Positional Accuracy Value:

250.000000

Vertical Positional Accuracy Explanation:

Methods of assessing vertical accuracy include statistical analyses of high-resolution DEM sources by their producers, assessments of contour intervals in some source maps, histogram analyses of DEMs lacking in more detailed assessments. (Histograms often show

Process Description:

The DCW hypsography was converted to 30" latitude-longitude grids by the U. S. Geological Survey. Prototyping of techniques also involved University College London. The ANUDEM contour-to-grid software of Australian National University was used, which incorporates streamlines to help guide the gridding process. The other cartographic source materials were also converted to grids by the same general methods. Those other sources, which were originally in hardcopy format, were adapted for input to this processing by the Geographical Survey Institute of Japan. The exception is the Antarctic Digital Database, which was also in digital format.
