Rock Mapper Knowledge Base - Rock Mapper 3.5

Release Date: April 2, 2026

New Liquid Glass design
Rock Mapper now follows Apple's latest iOS/iPadOS 26 design language.
Digital Geological Compass
Use your iPad to capture orientation measurements of planes and lineaments (e.g., faults, lithological contacts, intersection lineations, fold axis, etc.).
Pan and Zoom for rock face photographs
You can now zoom into face photos, and pan to the left wall, right wall as well roof / backs. Double tap to maximise the view.
Sample Bag ID Scanner
Instead of manually entering IDs printed onto sample bags, simply scan them using the iPad's camera.
Pictures and Attributes for POIs
Assign a picture and customisable attributes to POIs. Great for (geotechnical) inspections or to capture that small geological details (like a speck of visible gold). You can even annotate POI pictures. All POI pictures and attributes are included in the Mapping Report PDF.
Edit Annotations, Report Fields & Attributes
Annotation layers, report fields and attributes can now be edited or duplicated in the Settings. Simply long-press to open the contextual menu.
Other improvements & changes
- Improved/smart label placement and sizing on photographs and LiDAR scans.
- Auto-detect structure type when placing structural measurements on annotation lines (e.g., on a fault line).
- Copy / paste for sample interval data.
- New, simplified user interface for Structural Measurements / Orientations to streamline input. Structure type (Plane or Lineament) now directly defined in Settings > Mapping > Structures. All Contacts are automatically classified as type Plane.
- ❗New column SiteID added to [FaceID]_metadata.csv file.
- New green globe icon on thumbnails to indicate fully georeferenced rock faces.
- Device storage warning when device is running low on it.
- Zero delay face photo scaling and sampling grid generation after adding scale bar. Previously it could take a few seconds for complex / jagged face outlines.
- Orientation value check. If entered structural measurements are outside of valid range (e.g., dip = 124), then value is highlighted in red and can't be saved.
- Improved input for laser station and survey point coordinates. Pressing the return button on the virtual keyboard automatically moves cursor to next field.
- New show / hide POI comments. Previously POI comments were always visible, now they can be hidden on the photograph and 3D LiDAR scan.
- Mapping and Sampling report PDF preview and quick-share option. Long press thumbnail on rock face gallery page to open contextual menu and then choose PDF Report.
- What's New window to inform users about the most important new features and changes after updating.
- ❗New [FaceID]_history.csv file. Records events CREATE, UPLOAD, DOWNLOAD, EXPORT, IMPORT, SAVE, DUPLICATE, RENAME, GEOREFERENCE as well as DATETIME, RMVERSION, RMID and SITEID for each rock face.
- ❗New [FaceID]_POIs.csv file. Saves all info regarding POI pictures (PICTURE_NAME, VIEW_ORIENTATION, X, Y, Z) as well as all user defined POI attributes.

❗Indicates new files or files where format / structure has changed

IMPORTANT. Before updating to version 3.5, please follow these steps:

Upload OR export all rock faces and back up all your data (save the original ZIP files on your PC).
Make sure that you are running the latest version of iPadOS (26.4). Go to Settings > General > Software Update to check.
Make sure to perform step 1 and 2 on all your devices.
