General

Whatever type of map you are creating, Surfer helps you present your data in the most informative and dynamic way possible because you have full control over all map features. Experienced map users will appreciate Surfer's power and flexibility, and even inexperienced map users can quickly produce impressive, convincing maps. You can create outstanding maps using gray shades or full color, and enhance them with posted data or geographic features. You can then scale, clip, tilt, and rotate your maps to obtain precisely the presentation you want. Surfer's "intelligent" defaults are great, but once you define your own defaults, every map is drawn to your exact specifications. When you consider all the map types you can create with Surfer, and the ability to combine maps in overlays, the mapping possibilities are endless.

Data Manipulation

Surfer lets you interpret your XYZ data in many ways to achieve exactly the output you want. You can perform data manipulation using fully-controllable gridding operations or one of the many grid functions that let you massage your data to get the right answers to your questions. Surfer is simple to use and FAST! It takes less than one minute to produce an accurate contour or surface map from a data file with 10,000 XYZ points.

Surfer ships with three versions for use with Windows 3.1x, Windows 95, and Windows NT. It doesn't matter which version of Windows you are running because Surfer automatically utilizes the full capabilities of your computer.

Surfer supports OLE automation so you can accomplish repetitive tasks. Any sequence of operations you perform with the mouse or keyboard can be expedited by a single command with a Surfer macro.
