Surfer is a grid-based mapping program that interpolates irregularly spaced XYZ data into a regularly spaced grid. Data metrics allow you to map statistical information about your gridded data, and calculations for surface area, projected flat area, and volumetric calculations can be quickly performed in Surfer. Networks can also be imported from other sources, such as the United States Geological Survey (USGS). The grid is used to produce different types of maps, including contour maps, color relief and 3D surface maps, among others.
There are many grid and mapping options available that allow you to produce the map that best represents your data. Surfer's excellent grid and contouring capabilities have made Surfer the software of choice for working with XYZ data. If you want to use a Surfer single-user license, the product key must be activated when you log in to the account with which Surfer will be used.
