1-km GLCC landcover, Albers projection

Data set reference code -- 1998-0003

Corrected Data, 28 July 1998

The version of the land cover data created in January, 1998 was offset approximately 1 km from its correct position as a result of an error in the program used to resample the land cover data from the North American Lambert Azimuthal projection, in which the data are distributed by EDC, into the Albers projection. The Albers version has now been recomputed using a corrected version of the program. Note, however, that there may remain uncorrected differences in the latitude and longitude measured relative to the different spheroids used for the intitial and final projections. These offsets may be as large as 50 meters; they have been ignored since they are small relative to the resampling errors which result from the offsets of up to 500 meters between the centers of grid cells in the initial and final projections.
