Petroglyph V16 Khatm Al Melaha, Kalba, Sharjah

Natural Version, Petroglyph V16 Khatm Al Melaha, Kalba, Sharjah. Nubian Ibex. Likely Neolithic or earlier. [Fossati 2019 Messages from the Past: Rock Art of the Al-Hajar Mountains (Oman)]. Khatm Al Melaha is an archaeological site on the coast of the Oman Sea near Kalba in Sharjah, UAE. It is one of the largest rock art sites in the UAE. Over 175 stones with petroglyphs were documented and close to 400 motifs were identified. Every rock with a glyph was given an ID number and a GPS coordinate. In total 25455 terrestrial photographs, 5244 drone photographs, 44 drone videos, and 182 GPS points (+/- 1cm) were done in a single day. Petroglyphs were identified using Radiance Scaling in Meshlab, materials lighting in Substance Painter, and by changing conditions in Sketchfab. Some carvings were completely invisible when viewing. Drawings were done only when a line could be identified using one of these techniques.
