Follow these 6 steps to map a face and record face samples in Rock Mapper.
You can either capture a face photograph with the iPad's built-in camera or (wirelessly) transfer a picture from a digital camera to your iPad. In both cases we recommend to use a powerful and rugged LED light and a tripod to achieve best possible image quality. You can find more information in the hardware section.
For low-light photography we recommend to install the Camera+ 2 app. It allows to capture long exposure imagery in very dark environments with the iPad's built in camera. No extra camera needed, just a tripod with a tablet mount.
Import any picture that is stored on your iPad. Note that the most recent picture can be found at the bottom of the thumbnail list. Rock Mapper also allows you to 3D register and map on old/legacy face photographs. Just upload them onto your iPad (e.g., via a free iCloud account) and open them in Rock Mapper.
Digitise the face outline, add a scale bar and measure the orientation of the face using the iPad's built in magnetic compass. Then tap on a known point on the face such as the drive direction laser point and enter the distance to the drive direction laser station. Finally, choose a laser station from the reference point list. Done.
Rock Mapper is now able to register and store any mapped data in 3D space, even face samples.
Draw lithological contacts, structures and points of interest (POIs) directly onto the face photograph using user-defined annotation layers. 3D coordinates for all manually drawn lines & points are automatically computed based on the entered reference information (scale bar, orientation, distance to reference point & reference point coordinates).
Everything you draw in Rock Mapper by hand will be stored in a digital file format and send to your computer via the cloud.
Assign different lithologies to the face and record channel samples and point samples by simply drawing onto the face photograph.
Lithology values for each sample are automatically inherited from the map and sample length as well as 3D sample coordinates are computed based on the georeferenced face photograph. Channel samples can be drawn in any orientation, not just horizontally. Rock Mapper is smart and can compute azimuth and plunge values for these linear samples.
3D registered face photographs, mapping data, sampling data & auto-generated PDF reports are all sent to your computer via the Rock Mapper Cloud (licence needed), all by a simple push of the Sync button in the app. The data is then ready to use for 3D modelling (e.g., in Leapfrog Geo) or for planning and grade control purposes. No post-processing or file conversion needed because all data is provided in standard file formats
Last but not least, Rock Mapper generates face mapping and face sampling reports as PDFs. These reports summarise all face information in a standardized and practical format that is easy to share and print.
