You have imported enough data to begin constructing the conceptual model However before doing so you will create surfaces from the imported points data to represent the vertical boundaries of the geologic structures Creating Surfaces from Points 22 In Hydro GeoBuilder a surface refers to a set of interpolated points that represent the spatial distribution of an attribute Surfaces may represent changes in topography or geologic layers over space e g digital elevation models or the spatial distribution of properties such as conductivity storage and initial heads Surfaces can be imported from surface files using the import utility or they can be generated from e Point data objects by interpolating XYZ point data In this section you will interpolate the XYZ points data imported in the previous section e Boreholes to generate surface data objects These surface will be used later to define the horizons of the conceptual model Ground Surface The first surface you will generate will be interpolated from the Elevation attribute in the Boreholes data object and will represent the ground surface of the conceptual model To generate a surface data object from points data Right click anywhere in the Data Explorer Figure 3 Hydro GeoBuilder Demonstration Exercise Create Surface from the pop up menu The Create Surface dialog box will appear on your screen Figure 22 gt Create Surface x General Settings Int
