10-m elevation contour lines (color)

About this map:

This map conveys topography of southern Guam by means of contour lines with 10-meter interval. The contours were created from a 4-meter resolution LiDAR-derived DEM, by means of GIS spatial analysis techniques. 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. Sets of contours are shown in different colors based on the elevation they represent.
