About this map:

This map shows the elevation and relief of terrain in northern Guam. It was created from the 2-m resolution LiDAR-derived DEM by means of the Spatial Analysis Tool. LiDAR data were collected in 2007 by JALBTX for the Government of Guam. It consists of two separate layers: DEM classified into elevation intervals and colored and a hillshade (hypsometric tinted shaded relief) layer. This approach creates an illusion of viewing terrain in 3D, while also conveying elevation information.
