Lineaments - Lineaments Filtering

This module allows a new IL generation which will have only the lineaments inside an angular stripe or a size stripe in the selected IL (active IL). The IL must have lines and belong to the thematic, cadastral or numeric category.
   
Lineaments Filtering:

  • activate in the "Control Panel" the Thematic, Cadastral or Numeric IL model, that has the lineaments;
  • click on Analysis - Lineaments - Filter...;
  • in the "Lineaments Filtering" window:
    • Select the Direction and the Size to select if the lineaments will be filtered following the angular direction and/or size. When marking the Direction the user has to set an angular interval, Initial Angle and Final Angle, to define the angular stripe to be considered. The valid values for this angle are values in the 0 (east direction) to 180 (west direction) degrees. The direction considered is counter-clock wise. The Initial Angle has to be less than the Final Angle. The sizes are defined in meters and the Initial Size has to be less than the Final Size. In both cases, it will be also considered the initial and final values of the selection.
    • Next the user has to select a Category already defined in the data base and type a name for the Output IL which will have the filtered lineaments.
    • Finally, the user has to press the Apply button so the filtering will be executed. The Output IL will kept only the lineaments inside the Direction and Size interval defined by the user.
