Exploratory Analysis - Lineament 

The purpose of this module is to show the line exploratory analysis, lineament, inside in a selected Information Layer (active IL). The IL has to have lines and has to belong to a Thematic or Cadastral or Numerical category.

The analysis result is presented in plots and/or reports. The reports give information about the total number of lineaments, the total and average length of all lineaments and the total and average azimuth of all lineaments. These information can be presented in histogram or rosette plots, related to angular intervals defined by the user.

Executing Lineament Exploratory Analysis:

  • activate in the Control Panel the Thematic, Cadastral or Numerical IL model, which has the lineaments;
  • click on Analysis - Lineament - Exploratory Analysis...;
  • in the "Exploratory Analysis" window select the  Descriptive Statistics   operation and press the Apply button in order to get the Data Report with general information about the total of lineaments, the total length and average of all lineaments and the total azimuth and the average of all lineaments;
  • back on the Exploratory analysis window, select the Visualize operation to get lineaments distribution plots. In this case, you have to select the plot type, Rosette or Histogram, the angular Interval and the Variable to be considered in the plot generation: linear; bars, filtered linear or filtered bars.

NOTE:  Together with the plots, the Data Report window is presented with the numerical information used to generate the report. In the Data Report window you can save its contents using the ASCII text format, just by pressing the Save... button. In this case a Save As window is presented and you can select the directory and the file name to save the data.
