D 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 3. D 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. 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. D 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 3. D 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! A vector map of Mt. Helens overlaid on a contour map. Use a color scale bar or legend to indicate the magnitude of the arrows. 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, GTOP3. 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 1. 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 Change the rotation and tilt angles 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. Use post maps to display the location of your XY data. Different symbols are used to display different ranges of data in classed post maps. Here, a classed post map is overlaid on a wireframe map and 3. D label lines have been added to lift the symbols up off the map surface. 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 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, E0. 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. Display your base maps in Surfer alone or overlay them on other maps. Base Map Features Create any number of base maps on a single page Create independent base maps or overlay base maps on other map types Edit line, fill, text, and symbol properties for vector base map formats Specify real- world coordinates for TIF, JPG, GIF, and other raster files Independent scaling in the X and Y dimensions Rotate and tilt base maps to any angle 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 3. D 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 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.
