Coltop3D is a full featured software for the structural geological analyses of 3D point clouds. It is designed for the interactive analysis of geological structures from high resolution LiDAR or photogrammetric 3D point clouds and digital elevation models at local and regional scale. The software is capable of many applications and is optimized for data visualization and structural analysis in different domains:
Coltop3D can import LIDAR and photogrammetry point clouds and Digital Elevation Models. The software computes for each point an estimation of its orientation.
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.
A complete module for the visualization and formatting of stereoplots is under development and will be deployed in future versions.
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.
Coltop3D provides an easy mechanism for exporting data to third party software. Data format can be completely customized by the user.
