Including Drillhole data to draw cross-sections

Hi Guys

So far Im a major fan of GM, would it at all be possible to add borehole data input functionality so as to draw crossections from borehole data (lithologies). Other than that its a great product keep up the good work.

Regards

    Darryn,

    I can add that to the todo list, although it is a bit more specialized than the general thrust of Global Mapper and might be a bit out of my area of expertise.

    Thanks,

    Oh, I second this one! I realize it is stepping a bit out of GM typical domain but would be extremely helpful. I replicate this feature by putting in elevations of my lithology and set each soil/bedrock type in turn as "Elevation" for the points. You can then generate surfaces but it is a bit of a hassle to cut, export, and bring back each lithological layer in turn to generate the cross-section.

    Hi guys
    i was curious to know that if i can generate fault features as planes by assigning a dip angle and depth to them. Currently i am using line features to represent them.

    Hi Everyone!  I am following on the same topic.  

    1. How do you enter drill hole data with that is drilled at an angle?

    Can you explain your workaround?

    I would like this same feature to be added.  
    I believe that Global Mapper can already do all individual steps computationally, it would just be tying them together as a single function.  

    1. Distance, bearing, cogo line:  for drill data azimuth and dip angle are required, adding Z component to the feature.  
    2. For different lithologies or stratigraphic units intersected in borehole, points on a polyline could be used with attributes associated to each unit (bedrock, soil type, ore /mineral type).  

    3.  Gridded surfaces could be generated from all features with equal attribute:  Lithology, or stratigraphy, or water table, or ore/mineral type.
