To show the general physiography of Chuuk.
This dataset shows the general physiography of the islands in Chuuk Lagoon. The data layer was created by Island Research & Education Initiative (iREi) (2020)by scanning, georeferencing, and digitizing a set of paper maps prepared under the direction of the Engineer, Hq AFFE/8A, by the US Army Map Service, Far East; based on interpretations for road and airfield constructions by Harold G. May, 1954-1955; maps are titled "Suitability for Road and Airfield Construction Map, Truk Islands" and were compiled in 1957 by photogrammetric (multiplex) methods.

a. Scanned and georeferenced map to updated 2016 shoreline; b. Copied base layer and divided land polygon into varios sections based on paper map; c. Merged coral reef and lagoon polygons into single polygon; d. Added attributes shown on the map and additional attributes such as source, area etc.
To create a digital file in GIS format.
The map was created by the U.S. Geological Survey (1944) for the Chief of Engineers, U.S. Army. A photocopy of the map was found in the library collection at the national campus of the College of Micronesia (COM).
