The dataset covers 80 target villages across Phongsaly, Oudomxay, and Xiengkhuang Provinces, Lao PDR. The United Nations Satellite Centre's own very-high-resolution satellite imagery digitization fills data voids where open-source and government data are missing or incomplete, to support the Village Development Plan (VDP) process under the GeoCLEAR project. To support village-level baseline analysis (livelihoods, infrastructure, and hazard-exposure context) for the CLEAR project's 80 target villages, filling data voids where open-source and government data are missing, for the Village Development Plan (VDP) process.

The United Nations Satellite Centre is not the owner of the original source data and is not responsible for any misuse of this data. Features were reviewed and refined through visual interpretation of high-resolution satellite imagery at an approximate scale of 1:4,000; positional accuracy is limited by this interpretation scale and by the quality of the underlying source data. Data were refined specifically around the central locations of the 80 target villages to support village-level analysis and are not a comprehensive province-wide or national dataset. vector eng planningCadastre structure 100.901296 104.183224 19.303465 22.457321 true BuildingFootprint attribute definitions 2026-10-26 creation dataset Building footprint data derived from Overture Maps. The United Nations Satellite Centre reviewed and modified the features under the CLEAR Project through visual interpretation of high-resolution satellite imagery at an approximate scale of 1:4,000, refining them around the central locations of the 80 target villages in Phongsaly, Oudomxay, and Xiengkhuang Provinces, to fill data voids where open-source/government data were missing, supporting the VDP process. Data last updated 2026-10-26. Processing history: the Centre-modified building footprints were merged (ArcGIS Merge, 2026-10-17) with the Nga District building footprints prepared for the CLEAR Nga District flood analysis (a union of Overture Maps buildings and the Centre-modified footprints, 2026-10-01; flood depth-damage and loss attributes created in that analysis were deleted on 2026-10-11 and are not part of this layer); area attributes 'BFP_Area' and 'Area' were added (geodesic, square metres); the temporary ID field BFP_ID was removed on 2026-10-26.
