Geological mapping and structural measurements

JMapper

Map discontinuities directly on textured rock surfaces, link observations to an equal-angle stereonet, and examine structural sets and spacing.

Free during early access with a verified account. Models and project files stay on your computer. Use desktop Chrome or Edge.

Features

What you can do with JMapper.

Inspect the same rock surface in photographic texture, dip direction, dip angle and orientation colours to identify structural patterns.

Pick discontinuity traces and closed area outlines directly on the rock surface, with fitted orientations linked to the stereonet.

Compare alternative groupings of your measurements, inspect the proposed structural sets and confirm the interpretation you want to analyse.

Switch between confirmed sets to compare projected measurements, discontinuity spacing and trace lengths on a reference plane.
