Relief Map Oroville Dam by pmoews

Last crawled date: 3 years, 1 month ago

A group of space agencies, including NASA, has made digital elevation models for most of the earth. They are available as 1 degree squares (latitude and longitide) with pixels at intervals of 1 second - "Aster Global Dems". The square with lower left coordinates of 39 N 122 W has the Oroville dam near its center. The square was downloaded using Earth Explorer - https://earthexplorer.usgs.gov/ One is expected to state that "ASTER GEDEM is a product of METI and NASA"
Here are 3 relief maps calculated from the 39N 122W square. A representation of the whole square shows the Sacramento valley and the mountain range east of it; a prominent feature of the valley, the Sutter Buttes, is clearly seen. The position of the dam is marked with an asterisk. The danger faced by residents of Sacramento valley is obvious.
A close up using data at 1 second intervals shows the dam and a version a bit further away shows a large part of lake Oroville.
