ULTIMO RILASCIO: 1 Febbraio 2022

Surfer is a grid-based mapping program that interpolates irregularly spaced XYZ data into a regularly spaced grid. Grids may also be imported from other sources, such as the United States Geological Survey (USGS). The grid is used to produce different types of maps including contour, color relief, and 3D surface maps among others. Many gridding and mapping options are available allowing you to produce the map that best represents your data.

 

An extensive suite of gridding methods is available in Surfer. The variety of available methods provides different interpretations of your data, and allows you to choose the most appropriate method for your needs. In addition, data metrics allow you to map statistical information about your gridded data. Surface area, projected planar area, and volumetric calculations can be performed quickly in Surfer. Cross-sectional profiles can also be computed and exported.

 

The grid files can be edited, combined, filtered, sliced, queried, and mathematically transformed. For example, grids can be sliced to create cross-sectional profiles, or the Grids | Calculate | Isopach command can be used to create an isopach map from two grid files. Grids can be edited with an intuitive user interface in the grid editor.

WHAT’S NEW IN SURFER?

There are several new features in the latest release of Surfer! The top new features are listed below.

 

Top Features in Surfer’s Latest Release-

 

IMPROVED 3D SURFACE MAPS

 

New methods have been added to show the base on 3D surface layers. You can now select three different Z value settings to define to what Z value the base is shown. Previously, the base for the 3D surface layer filled the sides from the surface down to the minimum Z value of the grid file. Now you can select to show the base from the surface down to the minimum Z value in the map, to the minimum Z value in the grid, or to any Z value that you specify.

 

 

 

DIGITIZE IN 3D 

 

Before this new release, you could digitize your XY coordinates in 2D maps. Many of you use this feature to create blanking data. You can now perform the same type of digitization of data in the 3D view. 3D digitization collects XY and Z coordinates. Although you can use this new feature in a variety of functions, one function could be to obtain the XYZ coordinates of specific spot locations on a surface or points on subsurface drillhole paths.

 

This new feature works well with our new drillhole map. For example, when viewed in 3D, you can digitize specific locations at depth on each drillhole (e.g. the top of a unit or stratigraphic layer, determined by your displayed drillhole data). You can then go back to the 2D plot view, grid the digitized XYZ data, and add a contour layer from grid file to the existing drillhole map. The new surface will also be displayed in the 3D view with the drillhole paths!

 

 

NEW FRAMES FOR COLOR SCALE BARS AND MAP SCALE BARS

 

We have added two important enhancements to the visual appeal and aesthetics of maps that you need to present to clients or peers. You can now add and customize a frame around color scale bars and map scale bars. You can set the margin between the frame and text in the scale bars and you can define its fill and line properties. This is very useful when overlaying the color or map scale bar on top of a filled map, such as an aerial photograph.

 

 

MORE HELP WITH COLOR SCALE BARS

 

We know that many of you often build maps that have several layers and thus have several color scale bars. A new enhancement makes it easy for you to identify which layer a color scale bar belongs to. In the Contents window, click on one of the color scales and the name of the layer it is linked to is displayed in the Properties window.

 

 

MANAGE WARNING MESSAGES AND WARNING DEFAULT BEHAVIOR

 

Because of Surfer’s flexibility, the application warns you when changes you make to maps may create unintended consequences. For example, Surfer issues a warning when adding new layers to maps when the added layers have data outside the current map limits. You are asked if you would like to adjust the map limits to include all the data, or keep the limits as they are. These warnings give you the option of cancelling out of the change or accepting the change and continuing.

 

Some of you perform routine tasks that trigger these types of warnings repeatedly, always with the same response. To save you time and headache, we have made several of these warnings optional. You can either choose not to show the warnings in the future directly in the warning itself, or you can use the File | Options command and control whether to display the warnings or not, or specify the default action to take.

 

 

SAVE A GRID AS A GEOTIFF 

 

You could always export a map as an image TIFF, but now you can save a grid in GeoTIFF format, so that the Z values are saved to the TIFF file instead of colors for an image. Anywhere you can save a grid, you can select to save it in the TIFF Image as Grid format.

 

 

 

ENHANCEMENTS TO THE MAP WIZARD

 

The Map Wizard has some new wizardry! We have added Point Cloud and Peaks and Depressions maps to the available map types you can create. These enhancements work the same way as creating other map types from the Map Wizard, simply select the Home | Wizard | Map Wizard command, select your data or grid file and click Next. Select the map types you want to create! Note that you can only select Point Cloud map type if you selected a LiDAR LAS or LAZ file in the previous step, and then selected to load it as a point cloud.

 

 

QUICK ACCESS TO GRID INFO

 

We created a quick way to access commonly used grid information, by including this information on the Info property page for any grid-based layer. These new Info page contains information about a grid file itself, its XY geometry, and some Z statistical information.

 

The Info properties page is a quick way to see information for any grid in the plot window or the active grid in the Grid Editor. Simply click on a grid layer and select the Info properties page to view the information. You can even click the Copy button to copy and then paste this information into the plot window, or another application.
