3D
Surface Maps
Surfer 8 produces spectacular
3D rendered surface maps with complete control over
lighting and shading, position, rotation and tilt
angles. Overlay raster and vector base maps, contour
maps, image maps, shaded relief maps, post maps and
vector maps and specify the color modulation (surface
and overlay blending).

Grid
Mosaic
Combine adjacent and overlapping
grid and DEM files into a single GRD to produce a single
map. In areas of overlap, specify which grid nodes to
use with the average, first, last, minimum, or maximum
methods. Use the existing grid nodes, or resample at a
different grid spacing using bilinear interpolation,
cubic convolution, or nearest neighbor sampling
methods.

This surface map was
created with a grid resulting from the combination of
the Montezuma and Mt Evans Colorado 7.5 minute DEM
files. Vertical lines on the base represent offsets
caused by difference between UTM coordinates and
latitude / longitude definition of quadrangle
boundary
Cross
Validation
Select the Cross Validate option to
compare the Z value of a data point with the results of
gridding without that point. Write the results to a
statistics report and to a data file.
Specify the
number of points to validate, statistics report, and
results data file name.
Grid
Filter
The Grid Matrix Smoothing options
have been expanded into the new Grid Filter featuring
more than sixty predefined filters. In addition, define
your own filter parameters to refine your
grid.
Choose from a
large selection of predefined grid filters, or define
your own.
Data
Metrics
Create grid files and maps
illustrating spatial statistics within the search
ellipse such as number of data points, approximate
density, distance to nearest and farthest point, mean,
standard deviation, variance, and coefficient of
variation of the Z values.
Use the Data Metrics
gridding method to grid and map spatial variation of
statistical parameters.
Improved User Interface
Equals Increased Ease-of-Use
- Properties dialog
boxes optionally remain open and interactively change
to reflect the options available for each selected
object.
- 3D Trackball tool
facilitates changes to the tilt and rotation view
angles.
- Realtime Pan and
Zoom tools quickly change the display to the desired
section of the plot.

The 3D Trackball tool
lets you visually change the view of a 3D
plot.
Speedier
- Multithreaded redraw
results in faster screen updates and a more responsive
user interface.
- Gridding with faults
has been optimized for better
performance.
Larger
Worksheet
Read data files with up to one
billion (109) rows
and columns, subject to available memory.
Rotate and Tilt Raster
Maps
View your bitmap images from the
best angle. Rotate and 3D tilt shaded relief maps, image
maps, and raster base maps.

USGS DRG base
maps and other raster maps can be rotated and tilted to
any angle.
New Gridding
Methods
Surfer continues to dominate the
field with the addition of new gridding methods. New
methods include:
- Moving
Average
- Local
Polynomial
Other new gridding features
include:
- More flexible sector
specification
- View worksheet from
Grid Data dialog
- Sort and duplicate
check after specifying gridding parameters are
specified to enable faster data file loading
- Generate a report of
the gridding statistics and parameters including ANOVA
regression.
- Export Triangulation
and Natural Neighbor Delaunay triangle network to a
raster or vector file.
Export the
triangulation network to a raster or vector file, create
a base map
and overlay on a post map of the data
points.
New Variogram
Models
Surfer 8 adds the Cubic and
Pentaspherical models to the variogram
analysis.
Additional
variogram models give you more choices when
analyzing
your data.
Support for More File
Formats
More import and export options have
been added to the already long list of file
formats.
- Import Golden
Software GSI, ESRI E00, Windows Enhanced Metafile
EMF
- Export Golden
Software GSI & GSB, MapInfo MIF, Windows
EMF
Use USGS SDTS DEM and
DLG Files in Native Format
Use the new format USGS SDTS Digital
Elevation Model files (DDF) in Surfer to make contour,
surface, wireframe, vector, shaded relief, and image
maps.
Maximum Plot Size
Increased
The old 32-inch (81 cm) page limit
under Windows 98 and Me has been banished. The default
maximum page size is 110 inches (279 cm), with the
option to increase the maximum size to 2000 inches (5080
cm).
Download the Latest
Version with Internet Update
Check for the latest version of
Surfer 8 using your Internet connection. If there is a
newer version available, download and install it
automatically.
Surfer 8
makes it easier than ever to stay up-to-date with the
