Every so often we get contacted by users who would like to display contoured vertical sections of geophysical data, like GPR, gravity, or magnetic readings. Until recently, it wasn't possible to do this in Surfer, but with the new 3D Viewer and a little bit of data manipulation, you can! This workflow is easiest if your vertical sections run parall...

Cross sections are an important tool in illustrating subsurface geology.  Among the many new features added to Strater 5 are several new cross section options including water level display, retaining custom levels, and adding wells to an existing cross section. This blog will address how a new well can be added to a cross section. For this example, we will use the Cross Section.sdg sample file that ships with Strater.

The Strater 5 sample file “Cross Section.sdg” contains a cross section with four wells, well headers, two inset maps, a horizontal cross section, a depth log, and a legend. We will further manipulate this file by adding a new well and reshaping the default layers.

Golden Software recently hosted a training class on gridding and interpolating data in Surfer. Before the class was held, a user asked if we’d specifically cover the best options for gridding airborne geophysical data. At the time, it was not in the schedule, but as I looked at the data I thought this type of data could be very common and would make a great example. In this type of data, the data is taken in lines, where the data points along the lines are much closer together than the spacing between the lines.  Users generally want to interpolate the data to create a smooth color-filled image map while maintaining the data at sufficient resolution to show important anomalies.
