Follow these 5 simple steps to map a face, to record face samples and to sync all data in a fully georeferenced format via the cloud.
1. Capture photo ...
Capture a face photograph with the iPad's built-in camera (recommeded) or (wirelessly) transfer a picture from a digital camera to your iPad. Please use a powerful and rugged LED light for best image quality (more light, better pictures). Please visit the hardware section for more details about LED lights and other gear.
For tricky environments we recommend to use a tripod and install the Camera+ 2 app. It allows to capture long exposure imagery in very dark environments with the iPad's built in camera.
... or import photo
Import any picture that is stored on your iPad. Note that the most recent picture can be found at the top of the thumbnail list. Rock Mapper allows you to 3D register and map on old/legacy face photographs. Just email or upload them onto your iPad (e.g., via a free iCloud account) and then use them in Rock Mapper.
Use the georeferencing toolbar (lower left corner) from left to right. First, digitise the face outline, then 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 to compute the projected coordinates of the reference point. Done.
Rock Mapper is now able to register and store any mapped data as well as the face photograph and face samples in 3D space.
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 forwarded to your computer via the cloud.
Assign different sampling domains to the face and record Linear Sample Sets and Point Sample Sets by simply drawing onto the face photograph.
Domain values are automatically inherited for each sample and sample length as well as 3D sample coordinates are computed based on the reference information of the face photograph. Linear Sample Sets can be drawn in any orientation, not just horizontally. Rock Mapper is smart and automatically computes azimuth and plunge values for them.
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.
