Southern Guam geospatial information server
About this map:
This map shows the locations of ponding basins in southern Guam. The geospatial data were obtained from the Bureau of Statistics and Plans (BSP), Government of Guam. Locations were determined based on visual inspection of LiDAR-derived DEM and hillshade and satellite imagery (mainly WorldView2 by Digital Globe). Note that many ponding basins may have originated as natural features (karst sinkholes and other closed depressions) whose contours have been altered.
