Lithostratigraphic correlations sections may be broken down into individual columns and interpreted as vertical "drillholes" in GeoModeller provided that you know the location of each column. You may either model with or against the columns.

• With: convert columns into drillholes and use them as data input to build the 3D geological model.
• Against: build the 3D geological model without the columns, create dummy drillholes at their location and populate the geology from the model. Next, compare the results of the modelling to the columns and adjust the columns or model depending on which is more appropriate.
