Surfer 12

Surfer 12 was released January 14, 2014.  New Features  including reverseable axes, date/time format, log Z scale, download air photos from NAIP WMS (Web Map Services), save old formats, export drawn objects with a map, multiple post map labels, base map editing, blank a buffered convex data zone, and import and export new file formats including vector GeoPDF, JPEG2000, SVG, KML/KMZ and more.

Surfer is a contouring and 3D surface mapping software program that runs under Microsoft Windows. The Surfer software quickly and easily converts your data into outstanding contour, surface, wireframe, vector, image, shaded relief, and post maps. Virtually all aspects of your maps can be customized to produce exactly the presentation you want using Surfer’s software tools. Producing publication quality maps has never been quicker or easier.


Map Projections

Load maps in any map projection, and convert between projections.

Surfer now supports map projections! Choose from an endless list of coordinate systems for your map to display. Specify the source coordinate system for each of the layers in your map, and choose to display the map in any other coordinate system! For example, load data and grid files in UTM or State Plane coordinates, and display the map in Latitude/Longitude coordinates! It is simply that easy! Save the coordinate system information for your grid to an external file for future reuse.

Contour Maps

Surfer software’s contour maps give you full control over all map parameters.

You can accept the Surfer intelligent defaults to automatically create a contour map, or double-click a map to easily customize map features. Display contour maps over any contour range and contour interval, or specify only the contour levels you want to display on the map. And with the Surfer software you can add color fill between contours to produce dazzling displays of your maps, or produce gray scale fills for dramatic black and white printouts.

3D Surface Maps

The 3D surface map uses shading and color to emphasize your data features.

Change the lighting, display angle and tilt with a click of the mouse. Overlay several surface maps to generate informative block diagrams.

3D Surface Map Features

  • Specify surface color gradation, shininess, base fill and line color
  • Control mesh line frequency, color, style, surface offset
  • Set lighting horizontal and vertical angles, ambient, diffuse, and specular properties
  • Overlay contour maps, image maps, post maps, shaded relief maps, raster and vector base maps, and other surface maps for spectacular presentations
  • Choose overlay resample method and resolution, color modulation (blending) of surface and overlays
  • Change View tilt, rotation, field of view angles, perspective or orthographic projection
  • Set XYZ scales in map units or page length, choose proportional or independent XY scaling
  • Use data XY limits or specify a subset of the map
  • Control background fill and line color and styles
  • Add color scales to explain the data values corresponding to each color
  • Disable the display of blanked grid nodes or map the blanked areas to a specific Z level
  • Produce a detailed report of the grid statistics
  • Substitute a new grid file into an existing map

3D Wireframe Maps

Surfer wireframe maps provide an impressive three dimensional display of your data.

Use color zones, independent X,Y,Z scaling, orthographic or perspective projections at any tilt or rotation angle, and different combinations of X, Y and Z lines to produce exactly the surface you want. Drape a color-filled contour map over a wireframe map to create the most striking color or black-and-white representations of your data. The possibilities are endless.

3D Wireframe Map Features

  • Display any combination of X,Y, and Z lines
  • Use automatic or user-defined color zones to highlight different Z levels
  • Stack any number of 3D surfaces on a single page
  • Optional hidden line removal
  • Overlay any combination of contour, filled contour, base, post, and classed post maps on a surface
  • Views of the top or bottom of the surface, or both
  • Proportional or independent scaling in the X,Y, and Z dimensions
  • Full control over axis tick marks and tick labels
  • Add a base with optional vertical base lines
  • Display the surface at any rotation or tilt angle

Vector Maps

Instantly create vector maps in Surfer to show direction and magnitude of data at points on a map.

You can create vector maps from information in one grid or two separate grids. The two components of the vector map, direction and magnitude, are automatically generated from a single grid by computing the gradient of the represented surface. At any given grid node, the direction of the arrow points in the direction of the steepest descent. The magnitude of the arrow changes depending on the steepness of the descent. Two-grid vector maps use two separate grid files to determine the vector direction and magnitude. The grids can contain Cartesian or polar data. With Cartesian data, one grid consists of X component data and the other grid consists of Y component data. With polar data, one grid consists of angle information and the other grid contains length information. Overlay vector maps on contour or wireframe maps to enhance the presentation!

Vector Map Features

  • Define arrow style, color, and frequency
  • Symbol color may be fixed or based on vector magnitude
  • Display map scales, color scale bars, and vector scale legends
  • Scale the arrow shaft length, head length, and width
  • Control vector symbol origin
  • Choose from linear, logarithmic, or square root scaling methods

Image Maps

Surfer image maps use different colors to represent elevations of a grid file.

Create image maps using any grid file format: GRD, DEM, SDTS DDF, GTOP30 HDR. Surfer automatically blends colors between percentage values so you end up with a smooth color gradation over the map. You can add color anchors at any percentage point between 0 and 100. Each anchor point can be assigned a unique color, and the colors are automatically blended between adjacent anchor points. This allows you to create color maps using any combination of colors. Any color fill you choose for an image map can be used with any other image map, even if the associated grid files cover distinctly different Z ranges. Image maps can be created independently of other maps, or can be combined with other maps. They can be scaled, resized, limited and moved.

New Features in Surfer 12

Download Free Online Maps

More information is now at your fingertips. Download image layers from hundreds of free online Web Map Services (WMS) through Surfer’s new, integrated WMS browser. Connect to online data sources, pick the layers of interest you want to download, and Surfer seamlessly downloads and imports the images into your projects.

Grid and Display Maps with Log Z Scaling

Effectively display Z data that range over several orders of magnitude! You can grid data taking the log of the Z value prior to gridding, choose to have logarithmically scaled contour levels, or have logarithmic scaling applied to the color scale. This is extremely useful when your data file has extreme data ranges, such as concentration data where the Z values can span multiple orders of magnitude (i.e. > 1 to < 20000).

Post Map Enhancements

Create your post maps the way you want them! Many new enhancements have been made to post and classed post maps so that you can create the map you envision. Add multiple labels to points, connect the points with a line, and use the symbol color as the label font color, just to name a few.

Post maps also offer the ability to color the symbols using a column in the data file of either numeric values (and you can choose a color gradient to apply to the data range) or discrete color names. Classed post maps offer the option to apply a color gradient to the symbols, apply a gradational size to the symbols, and set the symbol properties for all symbols at once.

Creating just the right map of your point locations is better than ever!

“Loving the multiple post labels function – big thanks for that one!” – Shane Wilkes, Hydrogeologist
