Coltop3D is now developed by Terr@num. Get more information here:

Coltop3D is a full featured LIDAR data processing and analyzing software for geologists. It is designed for the interactive analysis of orientation of airborne and terrestrial LiDAR data and digital elevation models (DEM) at local and regional scale. The software is capable of many applications; it is optimized for data visualization and structural analysis in different domains:

  • Structural geology
  • Natural hazards
  • Mines and quarries
  • Civil engineering


Input data

Coltop3D can import LIDAR data point and Digital Elevation Model. The software computes for each point an estimation of its orientation.

Data visualization

Coltop3D provides many types of coloring schemes, notably its outstanding combination of a Stereonet plot and a computer graphics Hue-Saturation-Luminosity wheel. Hence, any Dip/Dip direction is mapped to a unique color. Structural features (joints, faults, folds) are easily detected.

Structural analysis

Coltop3D is a powerful tool for extracting and highlighting structural features, thanks to its unique selection tool. Selected data can be shown on Stereonet plots and basics statistics are computed.

Data exporting

Coltop3D provides an easy mechanism for exporting data to third party software’s. Data format can be completely customized by the user.
