Monitoring the Mass Balance of Eklutna Glacier, AK 202

Welcome Guest ( Sign In )

Overview

This lidar dataset was collected as part of an NCALM Seed grant for Caroline Brisbois at the Institute of Culture & Environment, Alaska Pacific University. This dataset was collected to compare airborne laser swath mapping versus structure from motion photogrammetry for monitoring the geodetic mass balance of the Eklutna Glacier. Lidar surveys were conducted over the Eklutna Glacier, east of Anchorage, Alaska.

Platform: Airborne Lidar

Survey Area: 175 km²

Raster Resolution: 1.0 meter
