Geology

Geology RMR is a specialized mobile app for geotechnical engineers performing Rock Mass Classification (RMR) surveys at tunnel excavation sites.

■ Key Features

• Create Field Stations

Capture up to 18 high-resolution photos at each station in the tunnel site and automatically upload them to the server to begin 3D reconstruction.

Record the Station ID, K+ location, excavation type and section, rock mass type, and mapping date.

• RMR Evaluation Report

Evaluate the following 6 criteria directly in the field according to Bieniawski’s Rock Mass Classification (RMR) system:

- R1: Undefective Strength (UCS)

- R2: Rock Quality Designation (RQD)

- R3: Discontinuity Spacing

- R4: Joint Condition (Continuity, Fractures, Roughness, Filling, Weathering)

- R5: Groundwater Condition

- R6: Orientation Correction

• Dashboard

Check the complete list of stations in the tunnel site and the processing status of each station (In Progress/Completed/Failed) in real time. • 3D Reconstruction Integration

When site photos are sent to the server, 3D tunnel model reconstruction begins automatically, and the results can be viewed in the app after completion.

• Multilingual Support

Supports Korean, English, and Vietnamese.

■ Target Audience

Geologists, rock engineers, and site supervisors at tunnel construction sites

■ Required Permissions

• Camera: Taking photos of the site rock mass

• Photo Library: Uploading existing photos

• Physical Activity Recognition: Optimizing screen orientation during shooting (using system library)
