Southern Guam geospatial information serverShore typeAbout this map:This map shows the different types of shoreline and distinguishes between sandy, rocky, muddy and artificial shoreline. The geospatial data were based on the updated shoreline data (Source: National Hydrography Dataset) and classified based on the artificial shoreline (non-earthen shore from the National Hydrography Dataset by USGS) dataset and visual on-screen interpretation of the 2011 QuickBird satellite imagery. This derived dataset was created by Island Research & Education Initiative for the purposes of this atlas. |
