Modeling Subsurface Layers in Surfer

Surfer block diagram depicting subsurface lithology layers
Golden Software customers work in a wide variety of industries, many of which are interested in modeling subsurface data. This data might be used for locating the water table depth, finding the extent of subsurface chemical contamination, delineating lithological horizons for cross section construction, and much more. Instruments and methods used i...

Industry Application: LiDAR Best Practices for Cultural Heritage and Archaeology Practitioners

The amount of LiDAR coverage for the Earth's surface has rapidly increased over the past few years, and a number of scientific disciplines are taking advantage of this increased availability of laser-derived data. Cultural heritage and archeology practitioners are no different, and the increased availability of LiDAR data is revolutionizing researc...

Gridding and Contouring Airborne Geophysical Survey Data

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.

You are correct that one degree of latitude is not the same as one degree of longitude. As you say, you could do the conversion ... Read More

Numerically Verifying Grid Results Through Surfer's Graphing Software

You’ve used Surfer mapping software to grid your data and created a great looking map. You put it in the final report for your presentation. And you think, that was easy and I’m all done now. And then someone asks you, how do you know that map is accurate? You start to wonder. How do I know if it is correct? Is there any way to verify the gridding? If the grid file matches the original data, then I could confidently say the map is correct. But, how do I know if the grid file matches the data?

In the previous blog, we discussed visually inspecting a grid to see if the grid created is a good representation of the original data. To do this, we compared a contour map from the grid to a classed post map from the data.
