Oroville Dam 2

A Second Look at Oroville Dam Unveiled Through ASTER Data Two detailed relief maps have been meticulously crafted using 10,000 data points centered near the iconic Oroville dam. The vertical scale has been deliberately exaggerated to highlight intricate details with utmost clarity. A map, ver_1, was calculated by utilizing an openSCAD surface file, while a second map, ver_2, was created by stacking 10,000 rectangular bricks with heights precisely proportional to the data points. Flat surfaces representing the height of each pixel can be seen in the stl file, showcasing its visual appeal and serving as a poignant reminder of the limitations inherent in the data. Fortran and openSCAD code are included for further analysis and exploration. A fresh perspective on the dam was added on March 3, 2017 Notes Careful examination of the raw data reveals that the height of the lake is given as 248 meters, while the height of the river below the dam measures a mere 70 meters. The height of the dam stands at approximately 275 to 280 meters. A scale factor of 0.04 plus a base of 2 was employed to create the maps - see the accompanying Fortran code. By cross-referencing the maps against Google earth images, one can verify their accuracy. Taking a trip back in time to 2013 using Google earth history reveals that the water level behind the dam appears to be remarkably similar to that depicted in the ASTER data. The entrance to the spillway is visible at the left of the dam, with a faint pathway at the left that could either be the spillway or the emergency spillway.
