Gridding

The Surfer gridding methods allow you to produce accurate contour maps and surface plots from your XYZ data. The data can be randomly dispersed over the map area, and Surfer's gridding will interpolate your data onto a grid. You have several gridding methods to choose from, so you can produce exactly the contour map or surface plot you want. And with each gridding method you have complete control over the gridding parameters. Or if your data is already collected in a regular rectangular array, you can create a contour map directly from your data. Computer generated contour maps have never been more accurate.
