WUDAPT information is organized by level of detail (L), and data at each level are gathered using distinct methodologies and techniques (Ching et al., 2018).

• the lowest level of detail (L0) maps cities and their surrounding natural landscape into local climate zone (LCZ) types
• L1 data use the LCZ maps to provide a sampling context for acquiring and managing information at finer scales.
• L2 data are complete information on all urban elements (e.g., building footprints, envelope fabrics, and heights) that may exist for some urban areas, albeit coverage is limited to a few cities
