create stratigraphic hierarchy

 

The create stratigraphic hierarchy module reads a special input file format called a pgf file, and then allows the user to build geologic surfaces based on the input file's geologic surface intersections. This process is carried out visually (in the EVS viewer) with the use of the create stratigraphic hierarchy user interface. The surface hierarchy can either be generated automatically for simple geology models or for every layer for complex models. When the user is finished creating surfaces the gmf file can be finalized and converted into a *.GEO file.

 

Boring States:

• Preserve Bottom tells the module that when the TIN has reached the bottom of a boring don't drop it from the geology but continue to add the same point to the remaining surfaces.

  • The Preserved state is automatically applied when the Preserve Bottom toggle is on, and you reach the bottom of the boring. 

• To Be Dropped is just for your information (this is not a state that you can set).  When the tin continues below a boring that boring gets dropped from the remainder of the surfaces.  

• Boring Dropped is a way of removing a boring from the geology for the current surface and below, this will happen automatically when the TIN reaches the bottom of a boring but can be done at any point by changing this state.
