In this imaging campaign about 3,000 aerial images taken from drone, using PPK/GNSS to position images.Salvation Mountain is a vibrant folk art installation located near Niland in the Colorado Desert of Southern California. Created by Leonard Knight over three decades until his death in 2014, this massive monument stands approximately 50 feet tall and spans 150 feet wide. The mountain is constructed from adobe clay, straw, and thousands of gallons of donated paint, displaying the simple message "God Is Love" in bold letters across its colorful facade. Biblical verses, flowers, trees, and inspirational phrases cover every surface in a kaleidoscope of vivid colors. Knight dedicated his life to this labor of love, declaring it a tribute to God and a testament to faith. Today, Salvation Mountain attracts visitors worldwide as both an artistic wonder and spiritual landmark in the desert landscape.Photogrammetry - Aerial33.253895381181-115.4729945557United States of AmericaJohn DriscollDominique RissoloFalko KuesterALERTCalifornia - UC San DiegoCultural Heritage Engineering Initiative (CHEI)
