New Features in Surfer 8
.
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).
Drape a raster or vector base
map on a 3D surface
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).
