In response to significant morphologic changes in Okmok Caldera due to the phreatomagmatic eruption of Okmok volcano in 2009, a new digital elevation model was acquired to document and quantitatively assess the new volcanic features and altered hydrology within the caldera.This DEM dataset provides elevation data derived from a stereo pair of Worldview-1 satellite images acquired on January 21, 2010.In addition to the DEM, a shaded-relief image is also provided for easy visualization of the data. |
