3D Wireframe Maps

 

Surfer 9 contouring software 3D 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.

 

A wireframe map can be used to display any combination of X,Y, and Z lines. A USGS SDTS DEM file was used to create this map and color zones were defined for the X and Y lines.

Vector Maps

 

Instantly create vector maps in Surfer. A vector map shows direction and magnitude of data at points on a map. You can create vector maps from information in one grid or two separated 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 direction of the arrow changes from grid node to grid node depending on the information surrounding the grid node. 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

 

A vector map of Mt. St. Helens overlaid on a contour map. Use a color scale bar or legend to indicate the magnitude of the arrows.

Image Maps

 

Surfer 9 contouring software image maps use different colors to represent elevations of a grid file. Create image maps using any grid-type file: GRD, DEM, DDF, 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.

 

Add color to your image map to customize it.

Image Map Features
  • Pixel maps or smoothed images
  • Dither bitmaps if needed
  • Create an associated color scale
  • Create custom color spectrum files for use on any image or shaded relief map
  • Overlay image maps with contour, post, or base maps
  • Data-independent color spectrum files
  • Specify color for missing data

Shaded Relief Maps

 

Surfer 9 contouring software 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 9 contouring software 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.

 

Adjust the light source angle when creating shaded relief maps.

Shaded Relief Map Features
  • Create photo-quality relief maps from grid files
  • Control light source position, relative slope gradient, and shading
  • Use custom color spectrum files for the exact desired display
  • Overlay with contour, vector, post, or base maps for highly effective displays
  • Shading calculations based on several shading methods including Simple, Peucker's Approximation, Lambertian Reflection, and Lommel-Seeliger Law
  • Set relief parameters using Central Difference or Midpoint difference gradient methods
  • Specify color for missing data

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.

Post Map Features
  • Create any number of post maps on a single page
  • Post from any number of files
  • Use proportional or fixed size symbols
  • Full control of symbol style, color, and frequency
  • Post data on contour, vector, surface, or base maps
  • Post every point or every nth point
  • Rotate and tilt post maps to any angle
  • Make a Classed Post Map to post different symbols for specified ranges of data values
  • Create a classed post legend to display the symbols and data ranges
  • Specify custom symbols from the worksheet
  • Add labels from a data file and adjust the angle of the label and the plane in which the label appears
  • Change data files without resetting post map and classed post map parameters

Base Maps

 

Surfer 9 contouring software can import maps in many different formats to display geographic information. You can combine base maps with other maps in map overlays, or can create stand-alone base maps independent of other maps on the page. You can load any number of base maps on a page. Base maps can be imported from DXF, GSI, BLN, SHP, LGO, BNA, GSB, DLG, LGS, MIF, E00, USGS SDTS DLG DDF, EMF, WMF, TIF, PCX, BMP, PLT, CLP, TGA, PCX, JPG, PNG, DCX, WPG, PCT, and other formats. It is easy to overlay a base map on a contour or surface wireframe map, allowing you to display geographic information in combination with the three dimensional data.

Map Overlays

 

Map overlays give you a way to combine any number of contour, wireframe, vector, base, and post maps. Draping a filled contour map over a wireframe map produces the most striking display of 3D data possible. And because you can overlay any number of maps, you can show any amount of data on a single map.

 

This map was created by overlaying two contour maps, a basemap, and a wireframe map in order to display contaminate spread.

Gridding

 

The gridding methods in Surfer 9 contouring software allow you to produce accurate contour, surface, wireframe, vector, image, and shaded relief maps from your XYZ data. The data can be randomly dispersed over the map area, and Surfer's gridding will interpolate your data onto a grid. You have a multitude of gridding methods to choose from, so you can produce exactly the map you want. With each gridding method you have complete control over the gridding parameters. If your data are already collected in a regular rectangular array, you can create a map directly from your data. Computer generated contour maps have never been more accurate.

Gridding Features
  • Interpolate from up to 1 billion XYZ data points (limited by available memory)
  • Produce grids with up to 100 million nodes
  • Specify faults and breaklines when gridding
  • Choose from one of the powerful gridding methods: Inverse Distance, Kriging, Minimum Curvature, Polynomial Regression, Triangulation, Nearest Neighbor, Shepard's Method, Radial Basis Functions, Natural Neighbor, Moving Average, and Local Polynomial

Variograms

 

Use the variogram modeling subsystem to quantitatively assess the spatial continuity of data. Variograms may be used to select an appropriate variogram model when gridding with the Kriging algorithm. Surfer 9 contouring software uses a variogram grid as a fundamental internal data representation and once this grid is built, any experimental variogram can be computed instantaneously.

 

Instantly create variograms in Surfer 9 contouring software to quantitatively assess the spatial continuity of your data.

Variogram Features
  • Virtually unlimited data set sizes
  • Display both the experimental variogram and the variogram model
  • Specify the estimator type: variogram, standardized variogram, auto covariance, or auto correlation
  • Specify the variogram model components: exponential, Gaussian, linear, logarithmic, nugget effect, power, quadratic, rational quadratic, spherical, wave, pentaspherical, and cubic models
  • Customize the variogram to display symbols, variance, and number of pairs for each lag
  • Export the experimental variogram data

Faults and Breaklines

 

Define faults and breaklines when gridding your data. The data on one side of the fault will not be directly used to calculate grid node values on the other side of the fault. When the gridding algorithm sees a breakline, any data points that lie directly on the breakline take precedence over an interpolated value. Use breaklines to define streamlines, ridges, and other breaks in slopes. Unlike faults, breaklines are not barriers to information flow and the gridding algorithm can cross the breakline to use a point on the other side. The gridding methods that support faults are: Inverse Distance to a Power, Minimum Curvature, Nearest Neighbor, and Data Metrics. Breaklines are supported by: Inverse Distance to a Power, Kriging, Minimum Curvature, Nearest Neighbor, Radial Basis Function, Moving Average, Data Metrics, and Local Polynomial gridding methods.

 

A contour map that features a fault is displayed here. Faults and breaklines are specified when gridding your data.
