Global Land One-kilometer Base Elevation (GLOBE) v.1

browse graphicGlobal color, shaded-relief map of GLOBE elevations.
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 candidate) 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) have 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 artifacts, as well as likely undocumented imperfections, in the data.

Processing Steps
  • 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.
  • The AUSLIG elevation point file was interpolated to a 30 arc-second gridfile using the GRASS-GIS function s.surf.idw (using 3 nearest points). This work was done at the National Oceanic and Atmospheric Administration, under an agreement with AISLIG, to produce a model for use in GLOBE.
  • The Italian DEM for gravity terrain corrections was resampled to 30" gridding by the National Oceanic and Atmospheric Administration, following a joint design by NOAA and the Servizio Geologico Nazionale of Italy.
  • The 500-m DEM for New Zealand was reprojected from the New Zealand national projection and datum to latitude-longitude 30" gridding by the U. S. Geological Survey.
  • The Zwally/NSIDC DEM for Greenland was resampled to 30 arc-seconds by the Jet Propulsion Laboratory, and blended with other data where available. The latter blended data were removed for transmittal to the GLOBE Task Team for GLOBE assembly, as they were unneeded.

  • All candidate data sets for GLOBE were evaluated, and blended using GRASS-GIS' function r.patch (with appropriate masking to avoid incorporating the wrong parts of candidates into the model.
