Abstract: The invention relates to a method for creating a three-dimensional soil model for a plot of land, particularly a building plot, wherein data is acquired in relation to a site plan of the plot, data is acquired in relation to a plurality of exploratory borings, which have been carried out on the plot at specific exploration points and for each exploratory boring a layer structure of the soil, with individual layers and their layer thickness, has been ascertained, and the individual exploration points are entered in the acquired site plan of the plot, wherein the individual layers for each exploratory boring are analyzed by means of a computer unit and are assigned in each case to a common soil layer, a layer thickness profile of the individual soil layers within the plot is interpolated depending on the position of the individual exploratory borings to one another, and the three-dimensional soil model for the plot is created by the computer unit in this way.
