Is it possible to automatically convert the gamma angle to true trend and plunge in Leapfrog Geo?

    @GeorgeSmith @ARMUTTAQIEN hi both! Do you any of you know how to convert this in LF Geo?

    Hello @NatsagdorjBatbayar. Yes, you can probably convert your gamma to trend and plunge by using a calculation. It cannot be done automatically.

    If you know the orientation of the bottom-of-core-line (probably the trend of the drillhole), and you know beta, then you should be able to calculate gamma. You could do this in Leapfrog or in Microsoft Excel. The calculation would look something like: [bocl trend + beta + gamma]. If the result is greater than 360, subtract 360.

    See part 1 of the online Leapfrog Structural Modelling Tools course in Seequent Learning, for more information.

    Since Leapfrog geo 2024 (definitely in LF Geo 2025) you can import and convert lineations recorded in alpha-beta-gamma format. Right-click on a Drillholes set name, then Import from file or Import from ODBC and there is an option for 'lineations'. This takes you to the usual import dialog where you select holeid, depth, alpha, beta and gamma columns from your data table.
