Alaska Coastal Profile Tool
The Alaska Coastal Profile Tool is an interactive, map-based tool that enables access to beach elevation profile measurements collected throughout Alaska since the 1960s. Users can explore profile measurements collected by the Alaska Division of Geological & Geophysical Surveys 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.
