Rock Mapper is compatible with any iPad that supports iOS 12.1 or later. For best user experience we recommend following hardware.

Apple iPad Pro with Apple Pencil

Rock Mapper is an iOS app that runs on any iPad (no Android version available). We recommend to use a 2018 or 2020 Apple iPad Pro (11 inch) because both have a high-quality, 12 Megapixel camera and support the 2nd generation Apple Pencil.
For the best experience when drawing on the screen we recommend to get a 2nd generation Apple Pencil. It's light-weight and very comfortable to use. It gets charged as soon as it is magnetically attached to the side of the iPad Pro.

Rugged / waterproof case

In order to protect your device from the rough conditions that are encountered when working underground it's advisable to get a ruggedized case for the iPad Pro. Some of them include a dedicated holder for the recommended Apple Pencil. Here is a list of selected cases that are currently available.




Unicorn Beetle Pro
Dux Plus
Survivor All-Terrain
Survivor Tactical

Please note that there are two different versions of the iPad Pro. Based on the year they were released, there is an iPad Pro (2018) and an iPad Pro (2020). They look very similar, but the iPad Pro 2018 has a single lens camera at the back whereas the iPad Pro 2020 features a multi-lens setup. Make sure to purchase a case that fits your model.

Laser distance meter

Most geologists already use a laser distance metre (aka laser disto) to measure the width of the face. In Rock Mapper this measurement is used to scale the face photograph. Additionally, using a laser disto the distance between the face and a reference point such as a drive direction laser station can be measured as well. Rock Mapper uses this distance to compute the 3D location of the drive direction laser point that is visible on the face. Here are a few selected laser distos:
Leica D2 (100m range)
Leica X3 (150m range)
Bosch GLM 100 (100m range)
Bosch GLM 250 (250m range)
Stabilia LD 520 (200m range)

LED light

In order to achieve best image quality we recommend to use a high power, rugged/waterproof LED light such as the BOSCH GLI 18V-1900 (1,900 lumens), Bosch GLI 18V-4000 (4,000 lumens) or Bosch GLI 18V-10000 (10,000 lumens) for underground face photography. More light, better pictures, even with a small camera/sensor.

Tripod (optional)

When increasing exposure time in order to acquire pictures under low-light conditions it's recommended to place the camera on a tripod (or stable monopod with base/feet) to eliminate motion and the associated motion blur. Even when capturing pictures directly with the iPad Pro the use of a tripod with a tablet mount can improve the image quality.

Digital camera (optional)

Underground face photographs can also be captured using a dedicated digital camera. We recommend to use a lens with a focal length between 12 and 18mm. Note that most modern digital cameras have WIFI built in, therefore images can be wirelessly transferred to the iPad while at the face and subsequently used in Rock Mapper. Based on the camera brand, please install the necessary image transfer app on your iPad.
Canon: Canon Camera Connect
Sony: Imaging Edge Mobile
Nikon: SnapBridge
Panasonic: Panasonic Image App

If you have a camera without WIFI then we recommend to get a SD card with built-in WIFI, such as the FlashAir W-04.
Use it with the FlashAir iOS app.
