PLEASE NOTE: This is the Version 1.2 release of the Eurasia land cover characteristics data base. It has not yet been validated and is subject to review. Following validation, the data base will be modified based on the lessons learned.
The Eurasia land cover data base is one portion of a global land cover characteristics data base that is being developed on a continent-by-continent basis. All continents in the global data base share the same map projections (Interrupted Goode Homolosine and Lambert Azimuthal Equal Area), have 1-km nominal spatial resolution, and are based on 1-km AVHRR data spanning April 1992 through March 1993. Each continental data base has unique elements that are based on the salient geographic aspects of the specific continent. In addition, a core set of derived thematic maps produced through the aggregation of seasonal land cover regions are included in each continental data base. These are:
The legends for each of these derived data sets can be found in Section 4.2 - 4.7.
For a description of the methodology for the global data base, see the global readme file found under the EROS Data Center DAAC home page (http://edcwww.cr.usgs.gov/landdaac/glcc/glcc.html).
The Eurasia land cover characteristics data are in a flat, headerless raster format. The pixel values correspond to class numbers defined in the appropriate land cover classification scheme legend. Data are distributed as compressed and uncompressed single-band images. The files can be obtained either by anonymous file transfer protocol (ftp) or downloaded from the EDC Distributed Active Archive Center (DAAC) World Wide Web site: (http://edcwww.cr.usgs.gov/landdaac/glcc/ea_int.html). The instructions for accessing these files are contained in the following two sections.
1.1 Anonymous FTP for PC or UNIX Users
1.2 Downloading from the World Wide Web Site
From the Eurasia Land Cover page, select either data in Interrupted Goode Homolosine projection, data in Lambert Azimuthal Equal Area projection optimized for Europe, or data in Lambert Azimuthal Equal Area projection optimized for Asia. The selection will link to a page that contains links to all documentation files and the image files (both compressed and uncompressed). NOTE: World Wide Web browsers can vary in how the files will be downloaded. On PCs, some browsers will allow a user to interactively select the location where the file will be saved and to edit the file name. However, on certain browsers files may be automatically downloaded to a default storage location on the local system.
The Eurasia data base is available in three different map projections: the Interrupted Goode Homolosine, the Lambert Azimuthal Equal Area optimized for Europe, and the Lambert Azimuthal Equal Area optimized for Asia (see Steinwand, 1994, and Steinwand and others, 1995, for a complete description of these projections).
2.1 Interrupted Goode Homolosine Projection Parameters
The data dimensions of the Interrupted Goode Homolosine projection for the Eurasia land cover characteristics data set are 8,570 lines (rows) and 13,800 samples (columns) resulting in a data set size of approximately 118 megabytes for 8-bit (byte) images. The following is a summary of the map projection parameters used for this projection:
Projection Type: Interrupted Goode Homolosine
Units of measure: meters
Pixel Size: 1000 meters
Radius of sphere: 6370997 m
XY corner coordinates (center of pixel) in projection units (meters):
Lower left: (215000, 104000)
Upper left: (215000, 8673000)
Upper right: (13584000, 8673000)
Lower right: (13584000, 104000)
2.2 Lambert Azimuthal Equal Area Projection Parameters
Because the Eurasia land mass covers an extensive range of longitudes, projecting the entire data set into an equal area projection results in extreme angular distortion for areas far from the projection's longitude of origin. Rather than reprojecting the data using one projection with a central meridian in the center of the Eurasia land mass, we have elected to use two sets of projection parameters for the Eurasia data base, one optimized for Europe and one optimized for Asia.
The data dimensions of the Lambert Azimuthal Equal Area projection for the Eurasia land cover characteristics data set optimized for Europe are 13,000 lines (rows) and 13,000 samples (columns) resulting in a data set size of approximately 169 megabytes for 8-bit (byte) images. The following is a summary of the map projection parameters used for this projection:
Projection Type: Lambert Azimuthal Equal Area
Units of Measure: meters
Pixel Size: 1000 meters
Radius of sphere: 6370997 m
Longitude of origin: 20 00 00 E
Latitude of origin: 55 00 00 N
False easting: 0.0
False northing: 0.0
XY corner coordinates (center of pixel) in projection units (meters):
Lower left: (-3000000, -4999000)
Upper left: (-3000000, 8000000)
Upper right: ( 9999000, 8000000)
Lower right: ( 9999000, -4999000)
The data dimensions of the Lambert Azimuthal Equal Area projection for the Eurasia land cover characteristics data set optimized for Asia are 12,000 lines (rows) and 13,000 samples (columns) resulting in a data set size of approximately 156 megabytes for 8-bit (byte) images. The following is a summary of the map projection parameters:
Projection Type: Lambert Azimuthal Equal Area
Units of Measure: meters
Pixel Size: 1000 meters
