Outcrop Mapper

Magnetic Declination

Outcrop now automatically calculates magnetic declination to improve the accuracy of bearing inputs and streamline data entry. A new Calculate button has been added to the Outcrop Bearing control, providing quick access to a dedicated Magnetic Declination dialog.

This dialog allows you to calculate declination using either the photo’s creation date (which is filled in by default) or a custom date. You can easily switch between these options using radio buttons and enter a custom date through a validated input field or date picker. This enhancement ensures that declination values align with the appropriate time-frame for your data.

Topography

Previously, when users added a Digital Terrain Model (DTM), it was imported only as an elevation surface that could be viewed in 3D. While this format was useful for terrain-based calculations, elevation surfaces were not easily visible on the map, often appearing as blank or white layers that provided little visual feedback. Now, the outcrop can be added as a 2D layer in the Map window and can be visualised with other GIS data.
