ACES-Dubai recently carried out the aerial photo and satellite imagery studies and interpretations for preparing a geological base map of the mountainous terrain (Hajar mountains) of the eastern province of Fujairah, UAE for the Etihad Rail Project. The base map shall support the detailed geological mapping to be carried out along the tunnel routes through the mountainous stretch of the project.
Aerial photography is the taking of photographs of the ground from an elevated position. The term usually refers to images in which the camera is not supported by a ground-based structure. Cameras may be hand held or mounted, and photographs may be taken by a photographer, triggered remotely or triggered automatically. Platforms for aerial photography include fixed-wing aircraft, helicopters, balloons, blimps and dirigibles, rockets, kites, poles, parachutes, and vehicle mounted poles. Aerial photo studies are carried out for preparing the base maps for geological, hydrogeological, transportation and infrastructure developmental project purposes
Over 52 photographs covering the mountainous stretch of about 22 km of the alignment were interpreted to prepare the base map in a scale of 1:3000 identifying the rock types, soil covers, slope wash covers, out crops of rock, major joints and discontinuities like fault/ shear zones, land slid zones, rock fall zones etc. for a regional appreciation the satellite imageries with a ground resolution of 5 m was used for firming up the interpretations on the aerial photographs.
