From satellite image we can extract and identify different linear features, which we consider it as lineament
please write your experience how we can differentiate between various structures as these extracted lineament may represent fault, joints, fractures..etc.
and please share if you have any references in this subject..??
Hello Hamdi,
It is also advisable to use the isolines of heights obtained from a digital elevation model. Also helps vegetation map. For example, on different sides of faults there may be different vegetation and texture.
You can use some of the techniques available for digital signal processing, especially those related to border detection.
Dear Hamdi Aldharab,
For your this query, I suggest you must go for the books given below:
1. "Remote Sensing Geology" authored by R. P. Gupta
2. "Remote Sensing for Geologists: A Guide to Image Interpretation" authored by G. L. Prost
I think, after reading these two books you will get a comprehensive idea about geological mapping using remote sensing.
Good Luck.
Dear Hamdi,
You can use various techniques like Grey Level Co-occurrence Matrix (GLCM) proposed by Haralick (1979) followed by various filters.
N.B: the techniques depend on images, environments...For us in tropical environment it is difficult to have a specific technique to differentiate geological structures. Please find attached an article with can help You.
Good Luck.
I think faults can be identified by using satellite images but joints or fractures specially on local scale are very hard.
For getting better results I suggest you to use UAV and also use Geomorphological tools.
