The feature class was created to illustrate the thickness of Quaternary sediment, north of latitude 56. These contours are generated from calculated values between surface objects (Top of Quaternary and Base of Quaternary) produced in Paradigm’s SKUA-GocadTM software. Contours are set to 20 m increments. They are exported as a DXF file and then imported into ESRI software where the feature class is created. |
