What’s New in Leapfrog Hydro 2.5.2

New features and enhancements in Leapfrog Hydro 2.5.2 are:

Import LAS Points

LAS 1.2 and 2 borehole logs can now be imported into Leapfrog Hydro. This import workflow can handle multiple LAS files and will convert them into a single borehole points table. Imported LAS files can be viewed in 3D as a single object, and columns of data common across all LAS files can easily be used as input into a numeric interpolant. Query filters are automatically created on import for each of the original LAS files, making it easy to see each of the individual files. See Importing LAS Points Down Boreholes for more information.

Batch Importing and Reloading GIS Data

Imported ESRI Geodatabases and MapInfo batch files are now added to the project tree as part of a parent object. This makes it clear whether individual GIS objects came in on their own or as part of an import from a Geodatabase or MapInfo batch import. These GIS collections can also be reloaded.

Extended Multicore Processing

In 2014, Leapfrog introduced the ability to use up to 4 cores when processing. Leapfrog Hydro 2.5.2 increases this capability to 8 cores. Those with high end computers with 8-core processors can now access all of their computer’s power to significantly reduce processing times when tackling complex modelling problems.

Updates to Previous Versions

Leapfrog Hydro 2.5

Exact Mesh Clipping

Switch on exact clipping for meshes, removing tags that overhang the clipping mesh.

For more information, see:

Colour Gradients

Enhance data visualisation with colour gradient import and export. Import colour gradients from various GIS or geophysics packages (.tbl, .clr & .lut).

To learn more, see Colour Gradients in the Colourmaps and Colour Gradients help topic.

Cross Section Layouts
  • Display assay data as bar and line graphs in section layouts.
  • Evaluate flow models on cross sections and add to section layouts.
  • Display sections in the 3D scene.
  • Export section layouts as GeoTIFFs.

To learn more, see the Section Layouts help topic.


Create subfolders to sort and file objects in projects.

To learn more, see Subfolders in The Project Tree.

Set Elevation of Points

Project onto a surface and overwrite the elevation/z value for points. Set the elevation of points that don’t project onto the surface.

To learn more, see the Setting Elevation for Points help topic.

Stratigraphic Sequence Improvements

Reduce the number of polyline edits needed. Constrain stratigraphic sequence surfaces using drillhole intervals and contact points.

To learn more about using stratigraphic sequences, see the help topic.

Add Interval Mid-points to Surfaces

Use extracted mid-points in the Points folder as inputs for surfaces.

Improved Project Tree Controls

Display lines in the project tree to better show relationships. In the Settings window, click on User Interface and enable Show Tree Lines.

More options enable rapid opening or closing of folders. Collapse the entire project by right-clicking on the top of the project tree and selecting Collapse All. Hotkeys for opening and closing folders include:

  • Ctrl + shift + left arrow collapses all folders.
  • Right arrow expands a collapsed folder or object but keeps child objects collapsed.
  • Shift + right arrow expands a collapsed folder or object and child objects.
  • Left arrow collapses an expanded folder or object but keeps child objects expanded.
  • Shift + left arrow collapses an expanded folder or object and child objects.

Hotkeys work with more than one object selected.

GIS Visibility in the Project Tree

A copy of all GIS data is created on import and projected on the topography. This projected copy is now visible in the project tree underneath the topography object.

Improved Tabbed Interface

In order to improve the way large dialogs interact with the scene view, there are new options in the project Settings window. You can choose whether tabbed dialogs open to the main window, a separate window or where the last tab was moved to. This improvement has been applied to drillhole tables, section layouts, image georeferencing, movie editing and image rendering.

Reload GIS Data

Reload GIS data to reflect changes during the project life-cycle. Automatically re-run and update dependant surfaces and models.

To learn more, see the Reloading GIS Data help topic.

GIS Line from Mesh Intersections

Create a new GIS line from two intersecting meshes. Use this for visualisation or as an input into Leapfrog models.

To learn more, see Creating a New GIS Line from Intersecting Meshes in the Creating a New GIS Line help topic.

Fast Copy for Geological Models

Rapidly copy the geological model for easier scenario testing.

Unshare Polylines

Create a local copy of any polyline when it is no longer correct or useful to share the same polyline.

To learn more, see Unsharing a Polyline in The Project Tree.
