Abstract: The present invention relates to a method of providing a geologic model representing geologic features based on geologic measurement dataset constituted by a number of data points sampled in a chosen region. The method includes the following steps: a) receiving at least one user selected control point (1) representing a geological feature in the measurement data set, b) providing an initial guide surface (2) with a predetermined shape, the control point (1) being positioned in said initial guide surface, c) comparing said initial guide surface shape with the sampled data points (4) for detecting measurement data points being similar to the measurement data of said control point (1), providing a vertical difference value representing the vertical difference between the depth of the guide surface and the depth of said corresponding data points for each compared data point in said set, d) from a selected set of said difference values, generating a new guide surface (5) corresponding to the control and data points.
