What's New in Surfer 7?

 

Double Precision

Surfer 7 is a 32-bit double precision application designed to run on Windows 95/98 or higher and NT4 or higher. Double precision allows you to display up to 15 decimal digits without losing precision.

Quicker

The speed of reading and writing binary files has been increased several fold. Surfer 7 is much faster!

New Map Type – Vector Maps

At the request of our users, we have added vector maps to Surfer 7.  You have full control over symbol style, color, frequency, and scaling.   Use one or two grid files to create your vector maps and Surfer 7 automatically computes the gradient of the represented surface.  Overlay your vector maps on contour, wireframe, post, or base maps for spectacular results.

Variograms

Instantly create variograms!  Interactive modeling, sophisticated data exclusion filtering, and simultaneous report generation are just some of the new features associated with creating variograms in Surfer 7.

Instantly create variograms in Surfer to quantitatively assess the spatial continuity of your data.

New Gridding Features

Two Surfer 7 gridding methods have been significantly enhanced to accurately grid your data.  The two enhanced methods are:

  • Minimum Curvature
  • Modified Shepard’s Method

In addition, we have added a new, state-of-the-art gridding method:

  • Natural Neighbor

Other Added Gridding Features include:

  • Powerful duplicate data resolution
  • Generate a grid of Kriging standard deviations
  • Specify either point or block Kriging
  • Generate a report of the gridding statistics and parameters
  • Customize search rules

Faults and Breaklines

Easily and quickly define faults and breaklines when gridding your data. The data on either side of the fault will not be used to calculate grid node values on the opposite side of the fault. Use breaklines to define streamlines, ridges, and other breaks in slopes

Automation – Complete Programming Control

Surfer 7’s powerful scripting support provides complete control through any Active X Automation controller, including Visual Basic.  Surfer 7 also includes Golden Software’s Scripter, a Visual Basic compatible development environment that makes it easy to write and debug scripts.  Scripts make it simple to automate your tasks and interact with other applications.

Some of our most popular scripts are available for free to our customers.   To download them from this site, click here!

Use USGS SDTS DEM and DLG Files in Native Format

Use USGS SDTS Digital Elevation Model files (DEM) in Surfer to make contour, wireframe, vector, shaded relief, and image maps just as you would utilize a regular GRD file. Use the SDTS DEM files in their native format; there is no need for a conversion!

Similarly, use SDTS USGS DLG files directly in Surfer 7 to define boundaries. They can be directly loaded into Surfer 7.

New 3D DXF Export

This long awaited feature has now been incorporated into Surfer 7!  Export your maps as 3D DXF files; then import them into your favorite CAD program.

Other New Export Options

New export options include: SHP, PNG, BLN, and BNA file formats.

Editable Contour Labels

Add, delete, and move individual contour labels on the screen to customize your map. Simply click on a contour label and drag it to a new location.

Object Manager

The new object manager graphically displays all the objects contained in the plot window. This feature simplifies the editing of any object. Select any object in the object manager and click on it to open that object’s dialog box. Move an object to the foreground or background by dragging it in the object manager. Hide or show an object from the object manager. With a click of the mouse, customize axes, maps, text, symbols, or other objects using the object manager.

Use the object manager to easily access and edit all the objects that appear in your plot window.

Worksheet

Use data files that are up to 5 million rows in size in the new worksheet. Other new features include the capability to print from the worksheet. Save your worksheet in any of the several file format types: XLS, CSV, TXT, BNA, BLN, SLK, and DAT. Import formats supported include: XLS, DAT, SLK, WKx, WRx, CSV, TXT, BNA, and BLN.  Other new features include the capability to print from the worksheet, cell formatting, double precision, and new statistics.

New Symbols

Surfer 7 uses customized True Type fonts and symbols.  Included are six new sets of symbols:

  • Oil and Gas Symbols
  • Wind Barb Symbols
  • Weather Symbols
  • North Arrow Symbols
  • Didger Symbols
  • Map Symbols

Use the new symbols in Surfer 7.  It is easy to change the symbol size and color.

Improved User Interface

Surfer 7 has many new features that improve the user interface.  Tabbed dialog boxes make it easy to find and edit object properties.  Use the Apply button to view your changes without closing the dialog box.  The toolbars can be floating or docked, allowing you to position them exactly where you need them.  Right click on objects to see object specific pop-up menus.
