i dati nei seguenti tipi di mappe: contour, 3D wireframe, vector, image, shaded relief, post, base.
La mappa può essere scelta tra quelle in archivio o creata miscelando gli elementi di diverse mappe; può essere poi personalizzata in tutti i suoi elementi al fine di arrivare al risultato desiderato.

Con Surfer la produzione di mappe di qualità è non è mai stata cosi veloce e semplice.

New Features in Surfer 9 torna su

See all your data! Make colors, map layers, fill patterns, images, and missing data for image maps and shaded relief maps transparent! You have full control over the opacity percentage.

No more guesswork! Save time and frustration by importing georeferenced image files in their real world coordinates, ready to combine with other map types. Also export your maps in georeferenced images files! You can save the spatial reference information in Golden Software Reference format, internal referencing format (ie. GeoTIFF), with an ESRI world file, or Blue Marble RSF format!

Surfer 9 adds the ability to expand your base maps to show you all the individual components of the base map! You can add, copy, paste and delete objects from a base map, or double click on a particular object to edit its individual properties. You can even reshape polylines and polygons in a base map! You can still collapse the base map, double click on Base and globally change the properties for all items in the map.

Project your data from more than 1,500 predefined coordinate systems or define your own custom projection or datum! Add frequently used coordinate systems to your Favorites list to be easily accessible in the future.

Area and length calculations are here! Surfer reports the area and perimeter length of polygons and the length of polylines in a base map. Simply double click on the polygon or polylines and the information is reported. The polygons and polylines don’t even have to be a part of the original base map file. Import the base map, enter the base map group and simply draw the polygon or polylines right on the base map! It’s that easy to get area and length values! 

Eliminate overlapping and unreadable post map labels by effortlessly moving individual post labels to new locations by dragging and dropping them with your mouse! Labels that have been moved can optionally be linked to the corresponding post map symbol with a connection line. 

Create your classes for a classed post map exactly how you want them, and save the settings to a file! Make your classed post maps consistent every time without having to manually enter the same class specifications and class settings over and over again.

Save classes and class settings to a file and load them into
other classed post maps!

Know Exactly Where You Are! Surfer 9 displays the exact XYZ coordinates of the cursor location when traversing a map! The coordinates update automatically as the cursor is moved.

Enable or disable the cursor tracking between multiple maps! Click the mouse on one map to see the location of the cursor click on all other maps in the plot window that use the same coordinate system! You can also link post maps to the worksheet data. Select a point in the plot window and the closest point in the worksheet will be highlighted, or select a point in the worksheet and that point will be identified in the plot window! 

Spatially filter your X, Y and optional Z coordinates in the worksheet. Filter your data prior to creating post maps, variograms, or grid files and saving the data for use in other programs. The spatial filter can be used to remove duplicates and exclude data based on an expression using the built-in, powerful expression language. 

Your maps are smoother than ever! Surfer 9 supports antialiased text and line display to help your maps look their best! Antialiasing is easily turned off at any point.

The plot window, worksheet window, and grid node editor windows are displayed as easily accessible tabbed documents! When more than one window is open, tabs appear at the top of the screen, allowing you to simply click on a tab to switch to that window.

Plot, worksheet and Grid Node Editor windows are displayed as tabs! 
Simply click on any of the tabs to access that window.

Easily create just the color you want! Choose from a standard palette of colors, select to match any color on the screen, or easily create custom colors!

Select the exact color and shade you want!

Use the new colormap system to assign just the right colors to your color spectrum! Quickly and easily choose one of the predefined colormaps from the Presets drop down menu, or create your own! Use the scroll control to zoom in to a particular area in the colormap to set the color nodes at precise data values.

The new colormap system makes it easier than ever to select a color
spectrum or create your own custom color gradient.

Surfer 9 makes it easy to overlay and remove map layers from maps! Simply drag map layers into and out of map frames, and delete individual maps layers from maps without having to break them apart first.

Post Maps

Post maps show XY locations with fixed size symbols or proportionally scaled symbols of any color. Create post maps independent of other maps on the page, or combined with other map layers. 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 sample locations, well locations, or 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 3D 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 data from any number of files
• Use proportional or fixed size symbols
• Full control of symbol style, color, and frequency

• Drag post map labels to place them exactly where you want them
• 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
• Save and load classes for a classed post map 
• Adjust the layer opacity

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!

Superior 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. Use Surfer’s default settings or choose from twelve different gridding methods. Each gridding method provides complete control over the gridding parameters, so you can produce exactly the map you want. If your data are already collected in a regularly spaced rectangular array, you can create a map directly from your data. Computer generated contour maps have never been more accurate.

Grid Functions

In addition to creating maps, you can perform a variety of functions using grid files. Just a few of the possibilities include:

• Calculating the volume and areas of grid files! You can calculate the planar and surface area, and calculate the volume between two grid files, or a grid file and any horizontal plane.
• Applying a mathematical equation to grid files. Examples include subtracting one grid file from another to create an isopach map, converting outliers to a minimum or maximum value, or multiplying one grid file by a conversion factor to convert the Z units from meters to feet.
• Applying grid filters to emphasize details or remove background variation in the grid file.
• Blanking specified regions in a grid file to prevent contours or map data from being drawn through those areas (ie. buildings, roads, or outside of field areas).
• Creating cross sections and topographical profiles.
• Combining multiple grid files into a single, easy to use grid file.
• Extracting subsets of grids or DEMs based on rows and columns.
• Transforming, offset, rescale, rotate, and mirror grids.
• Smoothing grid files to create smoother maps.
• Calculating first and second directional derivatives at user-specified orientations.
• Calculating differential and integral operators utilizing gradient, Laplacian, biharmonic, and integrated volume operators.
