About this map:
This map conveys topography of northern Guam by means of contour lines with 50 m interval. The contours were created from a 4-m resolution LiDAR-derived DEM. LiDAR data were collected in 2007 by JALBTX for the Government of Guam. Since LiDAR does not always extent to the actual shoreline (zero-contour), the shoreline shapefile was added to represent the zero-contour line.
