SurferA Powerful Contouring, Gridding, and Surface Mapping Package
Surfer is a contouring and 3D surface mappingprogram that runs under Microsoft Windows.
It quickly and easily converts your data intooutstanding contour, surface, wireframe, vector,image, shaded relief, and post maps.
Virtually all aspects of your maps can be customizedto produce exactly the presentation you want.
Producing publication quality maps

Data Files
Contain the input data provided by the user
Used to produce grid files, post data points
on a map
Supports various file formats containing
numeric x, y location and numeric Z values tobe modelled

Grid Files
Used to produce different types of grid-based mapsto perform
calculations volume, residuals, grid math
carry out blanking, smoothing, slicing
Contain a regularly spaced rectangular array of Zdata organised in rows and columns

Boundary Files
Contain x,y aerial data such asstate boundaries, rivers or pointlocations
Used to overlay a basemap onanother map or top specify theboundary limits of blanking, faults,break lines and slice calculations
Can be vector files, metafiles or bitmap files

Contour Maps
give you full control over all map parameters.
Display contour mapsover any contour range
and contour interval, or specify only the contour levels you want to displayon the map.
can add color fill between
contours to producedazzling displays of your maps, or produce grayscale fills for dramaticblack and white printouts. 7 9. 52 7 9. 54 79 .5 6 7 9. 58 79 .6 79 .6 2 7 9. 64 7 9. 66 79 .6 8 7 9. 7 7 9. 72

3D Surface Maps
The 3D surface mapuses shading and color to emphasize your datafeatures. Change the
lighting, display angleand tilt with a click of themouse.
Overlay several surfacemaps to generateinformative blockdiagrams.

3D Surface Maps
surface color gradation, shininess, base fill and line color
lighting horizontal and vertical angles, ambient, diffuse properties
Overlay contour, image, post maps, shaded relief, 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
color scales to explain the data values corresponding to each color
Produce a detailed report of the grid statistics
Substitute a new grid file into an existing map

3D Wireframe Mapswireframe maps provide animpressive three dimensionaldisplay of your data.Use color zones,independent X,Y,Z scaling,orthographic or perspectiveprojections at any tilt or rotation angle, and differentcombinations of X, Y and Zlines to produce exactly thesurface you want.Drape a color-filled contour
map over a wireframe mapto create the most strikingcolor or black-and-whiterepresentations of your data.The possibilities are endless.

Vector Maps
Instantly create vector maps toshow direction and magnitude of data at points on a map.The two components, direction andmagnitude, are automaticallygenerated from a single grid bycomputing the gradient of the
represented surface. At any given grid node, the directionof the arrow points in the direction of the steepest descent.The magnitude of the arrowchanges depending on thesteepness of the descent.
Overlay vector maps on contour or wireframe maps to enhance thepresentation!

Vector Map Features
Define arrow style, color, andfrequencySymbol color may be fixed or based on vector magnitude
Display map scales, color scale bars, and vector scalelegendsScale the arrow shaft length,head length, and width
Control vector symbol originChoose from linear,logarithmic, or square rootscaling methods

Image Maps
Image maps are raster maps based on grid files.
These maps represent Zvalues (e.g. elevations,element conc.) with user specified colors.
Blanked regions onimage maps are shown asa separate color.
