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:

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
