Global wildland-urban interface maps in 2000, 2010, and 2020, based on GlobeLand30

This dataset provides global wildland-urban interface (WUI) maps at a spatial resolution of 30 meters for the years 2000, 2010, and 2020. The WUI is defined as areas where the 200-meter buffers of urban areas (characterized by artificial surfaces) intersect with the 400-meter buffers of wildland areas, including forests, shrublands, and grasslands. These maps are produced based on land cover classification results from the GlobeLand30 datasets.

Projection Information:The projection information aligns with GlobeLand30 standards:

Projection: UTM (Universal Transverse Mercator) for latitudes from S85 to N85, using a 6-degree zone system without zone numbers.

Polar Azimuthal Projection: Applicable for latitudes from S85 to N90 and N85 to N90, with the projection surface intersecting at the South and North Poles.

Naming Convention:The file naming convention is as follows:

WUI_LHH_VV_YYYYlc030.tif

Where:

L = Latitude code (N for the Northern Hemisphere, S for the Southern Hemisphere)

HH = Number of UTM zone

VV = Starting latitude of the tile (each tile crosses 5° latitude)

YYYY = Year mapped

lc = Land cover abbreviation

030 = Spatial resolution of 30 meters

Example File Name:For instance, the file named WUI_n15_45_2020lc030.tif can be interpreted as follows:

WUI: Wildland-Urban Interface dataset

n: Northern latitude

15: UTM zone 15

45: Starting latitude of 45 degrees

2020: Product year of 2020

lc: Land cover classification

030: Spatial resolution of 30 meters
