Official version history and changelog information for the current version of Surfer Beta.

Surfer Beta 25.0.157 (September 8, 2022)

New Features and Improvements:

• Gridding: interpolate XYZC data and create a 3D grids (DAT, VTK or HDF formats)
• Create 2D maps from 3D grids, using slice Z value
• 3D View: create isosurfaces from 3D grids and calculate volumes
• 3D View: create volume renders from 3D grids
• Base maps: move label anchor points
• Map Limits/Size: when change coordinate system for map, Limits should be converted and size in the longest dimension remain the same

Surfer Beta 24.0.157 (July 5, 2022)

Improvements

• Drillhole layers: add layer leader lines
• Drillhole layers: disperse labels
• Base layers: add label leader lines
• Base layers: disperse labels
• Post layer: disperse labels
• Legend: do not stretch text/symbol/line/fill contents when stretching legend (only adjust the margin property), and only stretch proportionally
• Profile: XY Axis: automatically adjust Scaling and Limits when profile layers are turned off/on
• Profile from grid: update automatically when changing the grid
• Update the information in the About dialog

Fixes

• Internal Error when creating Worksheet window (EditBar.cpp, View.cpp, Worksheet.cpp)
• No longer possible to create a Variogram inside a base layer
• File | Open: some SRF files took a long time to open in due to an invisible color scale attached to a grid layer with a large data range
• Crash when closing worksheet
• Crash when closing Surfer after file not fully loaded
• Grid From Contours: some contours with ZLEVEL or Z Coordinate information are ignored
• Internal Error after assigning NoData to a grid using a DXF file containing polylines with collinear data (polygonutility.cpp)
• Automation: server exception when loading IMG file for relief map and app becomes unusable
• Automation: xMapPerPU and yMapPerPU not reporting correctly after scale transforms are applied
• Color Relief: Data limits don't update when changing from Reflectance to Color only after reload grid
• The "Lock Position" feature still allows a node to be moved when nudging with the arrow keys (some times)
• Bring to Front and Send to Back: Contents needs a refresh
• Colormap Editor: Data Value box is not updating when set to a negative value and clicking Apply
• Map Wizard: Entire grid was blanked error appears too early and prevents gridding
• Crash when adding empty base layer
• Assign NoData: inconsistent NoData assignment around the boundary line
• Moving with arrows moves object always left (or always right)

Surfer Beta 24.0.120 (March 30, 2022)

Improvements

• Convert Coordinates: resize dialog
• Convert Coordinates: improve usability of adding and deselecting control points
• Common graphic files: add GML extension
• Update EULA in Surfer for subscription licensing

Fixes

• 3D View: default camera is far away when Map and layer have different coordinate systems
• 3D View: Export 3D: some surfaces export with the axis labels in the wrong location
• 3D View: Export to VRML: textured surfaces with blanked areas can lose surface color
• 3D View: Surfaces: shading resolution doesn't work anymore
• AutoSave: failure during recovery prevents Surfer from running
• Base (vector) layer: changing Map coordinate system reverses image
• Base Map: Ellipse, Rounded Rectangle, and Rectangle did not name properly using Attributes
• Base(vector): zipped SHP files imported without coordinate system information when there was a PRJ in ZIP
• Copy/Paste Format: undo/redo of actions can create multiple color scales and lead to crash
• Crash when Undo Paste Format
• Frame: Inaccurate bounding box when loading document with color scale in older versions
• Grid Data: text contents keep expanding after error until they're out of the dialog
• Internal Error after redoing unchecking of 'Show color scale' property (ColorScaleNode.cpp)
• Internal Error when certain limits & scale are applied (Axis.cpp)
• Internal Error when gridding some data using CoKriging (anisotropy.cpp)

Surfer Beta 24.0.93 (February 1, 2022)

Improvements

• Map Wizard: remove Cokriging as a gridding method for simple gridding; and if gdMethod is set to Cokriging, change it to Kriging
• Defaults: Grid Data: add Cokriging option to gdMethod in UI and SET file description
• Common Document Files filter: Include .XLSX

Fixes

• Crash when closing plot document after working in Grid Editor
• 3D View: drillholes not displayed when the map had a geotransform
• 3D View: Export 3D PDF: exporting 3D surface layers lost the surface color
• Internal Error when importing some images as a base layer (rasterlayernode.cpp)
• Base from data: Labels: X offset for labels is very inaccurate when map did not have proportional XY scaling
• Grid from Contours: assigning NoData outside the convex hull produced different contours than when not assigning NoData
• Copy Format/Paste Format: does not copy/paste polyline End Styles
• Base(vector) layer: Labels: offset not correct when page units were cm

Surfer Beta 24.0.79 (January 5, 2022)

New Features and Improvements:

• Grid Editor: display post/classed post layers for context
• Grid Editor: display base (vector and raster) layers for context
• Save As from worksheet: always append the file extension from Save as type to file name, if not already entered
• Convert coordinates of base (vector) layers using either a math or a georeference operation
