Individual fault and fracture data can be collected in 2D and 1D sections through measurements along linear traverses called scanlines. However, data obtained using this technique usually are not obtained with the level of accuracy and precision desired. The measurements are strongly dependent on the observation scale. Therefore, this work presents a method to compute information regarding the spatial variability of fracture and fracture set measurements collected along linear scanlines. We present results from a program developed in MATLAB used to obtain discrete fracture network (DFM) and finite element mesh (FEM) honoring some characteristics of spatial variability. However, it was possible to construct representative models of the geological environment and identify some limitations of scanline technique. That is because we started from data collected in one dimension and try to extrapolate to build models in two and three dimensions.
