Type Shapefile
To show the locations of houses and other buildings on Chuuk.
This map shows the locationsof all houses, buildings, and other human-made structures on the islands in Chuuk Lagoon. The dataset was created by Island Research & Education Initiative (iREi) (2020) by manually digitizing all structures visible in 2014 WorldView-2 satellite imagery by Digital Globe provided by U.S. Department of Agriculture (USDA) - Natural Resources Conservation Service (NRCS).

The dataset is believed to be complete at the time of creation. However, offices (especially smaller organizations) do move and locations may have to be updated.
The attributes are believed to be accurate. However, it is possible that buildings might have been mis-identified in the imagery.
Field verification of buildings using hard copy map.
The absolute accuracy is not known but is assumed to be within few meters.
Visual comparison with WorldView-3 satellite imagery.
