About this map:

This is a topographic map of northern Guam. The topographic maps of Guam were created by United States Geological Survey (USGS) at 1:50,000 and 1:24,000 scales (also known as 7.5-minute quadrangles) and are available as scanned and georeferenced maps and hard copy paper maps. The map used here is the scanned and georeferenced version, generally referred to as Digital Raster Graphics (DRGs), which was digitally cut to show northern Guam only.
