Dips is designed for the interactive analysis of orientation based geological data. The program is capable of many applications and is designed for both the novice user and for the accomplished user of stereographic projection who wishes to utilize more advanced tools in the analysis of geological data. Dips allows the user to analyze and visualize structural data following the same techniques used in manual stereonets. In addition, it has many computational features, such as statistical contouring of orientation clustering, mean orientation and confidence calculation, cluster variability, kinematic analysis, and qualitative and quantitative feature attribute analysis. Dips is designed for the analysis of features related to the engineering analysis of rock structures, however, the free format of the Dips data file permits the analysis of any orientation-based data.
