Identification of lineaments using Google Tools

Abstract

Recent advances in data acquisition technologies, have led to a growing interest in capturing high resolution rock surface images, Digital geologic maps that use a virtual globe interface, like google earth are a relatively new medium for presenting geologic data and interpretations. Models viewed in google earth are more intuitive for visualizing 3-D geological structures than traditional paper maps. Google earth displays satellite images of varying resolution of the earth's surface, allowing us to see things looking perpendicularly down or at an oblique angle, with perspective. Geological lineaments represent the intersection between discontinuity planes and an observation surface. Lineament identification plays key role in an underground project in all phases of the investigations and construction stages. Lineaments perceived in google earth images are reliable indicators of geologic structure. For identification of lineaments, google earth images technique is the most effective tool in conjunction with ground truth and toposheet for collection of spatial information and very useful in identification and mapping of the lineaments of an area. Structural geology studies, geologic lineaments and their pattern information are essential for better planning and timely execution of projects to avoid any hazards, google earth images provide lineament information.

Issues, reality and role of geologists on hill site development in Malaysia – Case study from a luxurious housing project in Taiping, Perak

“…Ini bertujuan untuk mengenalpasti keadaan topografi, saliran semulajadi, bentuk rupabumi, struktur geologi major (lineamen negatif) dan sejarah aktiviti manusia dan perubahan-perubahan fizikal yang berlaku di kawasan tersebut. Penggunaan imej satelit yang dimuat turun daripada Google Earth terbukti membantu untuk mendapatkan maklumat kritikal geologi (Lageson et al, 2012;Rana et al, 2016) disamping mendapatkan gambaran awal keadaan tapak kajian.…”

Geological and geophysical studies for multiple hazards assessments in an occupied residential area, Puchong, Selangor

“…Imej satelit yang dimuat turun daripada Google Earth digunakan dalam kajian ini. Kualiti imej satelit yang baik sangat membantu dalam proses penyiasatan geologi kerana kemampuannya memberi maklumat seperti perubahan keadaan topografi, saliran semulajadi, bentuk rupabumi, struktur geologi major (lineamen negatif), elemen geobahaya, sejarah aktiviti manusia dan perubahanperubahan fizikal yang berlaku (Hu et al, 2013;Lageson et al, 2012;Rana et al, 2016;Yu & Gong, 2012).…”

“…The introduction of aerial photos and later on satellite images were important steps in lineament interpretation tools [7][8][9][10]. Nowadays, satellite images can easily have downloaded using Google Earth Pro and proved to be a highly effective tool for gathering lineament orientation and spatial distribution data across these wellexposed anticlines [11,12].…”
