Data­Set Citation:

Bailey, R.G. 1989/1993. Bailey Ecoregions of the Continents (reprojected) from the World Conservation Monitoring Center. Digital vector data on a 0.3 degree resolution Cartesian Orthonormal Geodetic (lat/long) global polygon network and derived raster data on a 10-minute Cartesian Orthonormal Geodetic (lat/long) 1080x2160 grid. In: Global Ecosystems Database Version 2.0. Boulder, CO: NOAA National Geophysical Data Center. One independent spatial layer with three attributes. 10,235,790 bytes in 15 files.

Projection:

Cartesian Geodetic (lat/long)

Spatial Representation:

(1) Vector polygonal classed units at a claimed scale of 1:30,000,000.

(2) 10-minute global 1080x2160 grids rasterized from the vector data

Temporal Representation:

Static modern composite.

Data Representation:

Classes represented in an attribute values file, linked to areas by numerical code.

Layers and Attributes:

One vector layer with three attributes; with the same data represented in three dependent single-attribute raster layers.
