Various affordable, operational technologies such as remote sensing, Geographic Information Systems (GIS) can significantly contribute to improved efficiency. The main focus of the project has been directed to the use of remote sensing to gain geological and geohazard information. This study examines the use of Remote Sensing (RS) technology in geological studies of Kainji area. Radar SAR images were used to classify the various geological fractures found in the area located in the Northern part of Nigeria. A wide variety of digital image processing techniques were applied such as the Principal Components (PC) analysis and ratioing. ERS-1 SAR image that …

Box counting is widely used for characterizing fracture networks as fractals and estimating their fractal dimensions (D). If this analysis yields a power law distribution given by N $\propto$ r−D, where N is the number of boxes containing one or more fractures and r is the box size, then the network is considered to be fractal. However, researchers are divided in their opinion about which is the best box‐counting algorithm to use, or whether fracture networks are indeed fractals. A synthetic fractal fracture network with a known D value was used to develop a new algorithm for the box‐counting method …
