Surfer is a contouring and 3D surface mapping program that runs under Microsoft Windows. It 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. Producing publication quality maps has never been quicker or easier.

Features

• Contour Maps
  Surfer 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 Surfer 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 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.
• 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!
• 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.
• Shaded Relief Maps
  Surfer Shaded Relief maps create a shaded relief map from a grid [.GRD] file or USGS DEM file. These maps use different colors to indicate surface slope and slope direction relative to a user-defined light source direction. Surfer determines the orientation of each grid cell on the surface, and assigns a unique color to each grid cell. Colors on shaded relief maps are associated with light striking the surface. The light source can be thought of as the sun shining on a topographic surface. Surfer automatically blends colors between percentage values so you end up with a smooth color gradation over the map. You can add color anchors so 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. Shaded relief maps can be created independently of other maps, or can be combined with other maps in map overlays (using the Overlay Maps command). Shaded Relief maps can be scaled, resized, limited, and moved in the same way as other types of maps.
• Post Maps
  Post maps show X,Y locations with fixed size symbols or proportionally scaled symbols of any color. Create post maps independent of other maps on the page, or overlay the posted points on a base, contour, vector, or surface map. For each posted point, specify the symbol and label type, size, and angle. Also create classed post maps that identify different ranges of data by automatically assigning a different symbol or color to each data range. Post your original data point locations on a contour map to show the distribution of data points on the map, and to demonstrate the accuracy of the gridding methods you use.
