Welcome to Surfer, a powerful contouring, gridding, and surface mapping package for scientists, engineers, educators, or anyone who needs to generate maps quickly and easily. Producing publication quality maps has never been quicker or easier. Adding multiple map layers and objects, customizing the map display, and annotating with text creates attractive and informative maps. Virtually all aspects of your maps can be customized to produce the exact presentation you want.
Surfer is a grid-based mapping program that interpolates irregularly spaced XYZ data into a regularly spaced grid. Grids may 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, color relief, and 3D surface maps among others. Many gridding and mapping options are available allowing you to produce the map that best represents your data.
An extensive suite of gridding methods is available in Surfer. The variety of available methods provides different interpretations of your data, and allows you to choose the most appropriate method for your needs. In addition, data metrics allow you to map statistical information about your gridded data. Surface area, projected planar area, and volumetric calculations can be performed quickly in Surfer. Cross-sectional profiles can also be computed and exported.
The grid files can be edited, combined, filtered, sliced, queried, and mathematically transformed. For example, grids can be sliced to create cross-sectional profiles, or the Grids | Calculate | Math command can be used to create an isopach map from two grid files. Grids can be edited with an intuitive user interface in the grid editor.
The Scripter TM program, included with Surfer, is useful for creating, editing, and running

Who Uses Surfer?
People from many different disciplines use Surfer. Since 1984, over 100,000 scientists and engineers worldwide have discovered Surfer's power and simplicity. Surfer's outstanding gridding and contouring capabilities have made Surfer the software of choice for working with XYZ data. Over the years, Surfer users have included hydrologists, engineers, geologists, archeologists, oceanographers, biologists, foresters, geophysicists, medical researchers, climatologists, educators, students, and more! Anyone wanting to visualize their XYZ data with striking clarity and accuracy will benefit from Surfer's powerful features!
The system requirements for Surfer are:
- Windows 7 SP1, 8 (excluding RT), 10 or higher
- 512MB RAM minimum for simple data sets; minimum of 1GB RAM with additional cores are recommended when large data files are used
- Graphics card with OpenGL v3.2 or later. AMD and Nvidia graphics hardware are preferred. The following shader support lends to optimal visualization:
- Vertex shaders
- Fragment shaders
- Geometry shaders
- GLSL (GL Shading Language) 150
- Graphics emulators, such as VMs and Parallels for Mac, may not support all the required features
- At least 500MB free hard disk space
- 1024x768 or higher monitor resolution with a minimum 16-bit color depth.
Fine Tuning Surfer Performance
- Issues with 3D View features may be corrected by upgrading to the latest graphics drivers
- Many heavily computational operations, including gridding and contouring, are multi-threaded and processor reliant. A faster processor will improve Surfer's performance.
- For processing very large data files, such as LiDAR or some vector data files, fast and large RAM storage capacity is recommended.
- Click the File | Options command and on the General page, set the Max number of processors to use all processor cores.
- Click the File | Options command and on the General page, set the Save auto recovery information to off to improve performance.
