| The data used to create the 3D geological model were in various formats. The first steps of the data processing were the conversion from feet to meters and from spatial reference NAD 27 to NAD 83, the transition from Township/Range system to latitude/longitude coordinates and the transition from depth to elevation data (the reference is the mean sea level). Then the two available DEM files were merged to obtain a unique DEM. The geological data were standardized on both sides of the international border. The 3D geological model was then built using the software Leapfrog Hydro 2013. The approach to build it was to use location data (x, y, z) representing the top of the geological units. Contact surfaces were first created from these data. Then, volumes were obtained from the surfaces for which a chronology had been first determined. The model was adjusted with the help of cross-sections existing for the study area. The cross-sections served as a guide and allowed adjustments of the geological surfaces by manual editing within Leapfrog Hydro. |
