MODIS Vegetation Continuous Fields

Data Access

Global mosaics of the standard MODIS vegetation continuous fields data product (MOD44B) percent tree cover attribute are reprojected into geographic coordinates of latitude and longitude on the WGS 1984 coordinate reference system (EPSG: 4326). The data set boundaries are -180.0 <= longitude <= 180.0; -64.0 <= latitude <= 84.0. The data are organized as an array of values uniformly spaced across latitude and longitude and indexed with [0, 0] at 84.0 latitude, -180.0 longitude.

Spatially aggregated data for each year in the period 20002010 are available at two spatial resolutions:

  • 5' x 5' resolution comprising 1776 rows x 4320 columns at a geographic pixel size of approximately 0.083333; and
  • 0.5 x 0.5 resolution comprising 296 rows x 720 columns of 0.5 pixels.

The global land cover data sets are available as GeoTIFF format files (*.tif) with embedded metadata or as ESRI ASCII Grid format files (*.asc) with limited metadata in header lines. Native resolution data in the GLCF tile framework are available as GeoTIFF format files (*.tif).
