3. APPLICATION OF SURFER
CONTOURS 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.
 Full control over contour label format, font, frequency,
placement, and spacing .
 Color fill between contours, either user-specified or as an
automatic spectrum of your choice.
 Regulate smoothing of contour lines and
Reshape contour lines .

5. APPLICATION OF SURFER (CONT…)
 3D SURFACE MAPS:
In mathematics, geology, and cartography, a surface
map is a 2D perspective representation of a 3-
dimensional surface. Surface maps usually represent
real-world entities such as landforms or
the surfaces of objects.

7. APPLICATIONS OF SURFER (cont..)
 3D WIREFRAME:
 Wireframes are three-dimensional representations of a
grid file. Wireframes are block diagrams generated by
drawing lines representing the grid X and Y lines (the grid
columns and rows). At each intersection of a column and
row (i.e. at each grid node), the height of the surface is
proportional to the grid Z value at that point. The number
of columns and rows in the grid file determines the
number of X and Y lines drawn on the wireframe.

 VECTOR MAPS:
Instantly create vector maps in Surfer to show
direction and magnitude of data at points on a map.
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.
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.

11. APPLICATIONS OF SURFER (cont…)
 BASE MAPS:
 Map having only essential outlines and used for the
plotting or presentation of specialized data of various
kinds.
The function of the base map is to provide background
detail necessary to orient the location of the
map. Base maps also add to the aesthetic appeal of a
map.

13. APPLICATIONS OF SURFER (cont…)
 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.
