This interactive tool enables access to beach elevation profile measurements collected throughout Alaska since the 1960s. Users can explore profile measurements collected by DGGS and others as time-series plots and location-based images of the shoreface environment. The map has been designed to accommodate datasets collected with differing techniques, including differential leveling, survey-grade GPS or extraction from lidar-derived digital elevation models.

Lines on the overview map depict the position and shape of the most recent data at each coastal profile; remeasured profiles are displayed as coincident for comparative purposes, however, the precise location of past measurements may vary due to differing collection methods.
