I've got a geopak cross section stack file in which I have drawn my geology. I would like to create an accurate dtm and then a tin of each geology layer.
Current procedure:
Use DTM Input to create a .dat file of each individual layer.
Build Triangles from that dat to create my tin file.
To check this, I like to re-draw the surfaces that I have created in my cross-section file. I'd say probably 90-95% of them are accurate. There are, however, times when the new surface deviates from the line over a short section.
In other cases, there are great differences between what is returned and what I have drawn, as shown in the picture. The purple dash line is my original surface. The bright pink line is the check. I've double-checked symbology, and that isn't the problem.
So the question is... What's up? Why does it do this? How can I prevent it? I'm worried things like this will affect quantity calculations or other design things on down the road. Is there an alternate method that would serve me better?
Second auxiliary question, when I create surfaces like this, is there a way to prevent a layer from being "triangled" above a certain layer, for instance a road cut where geology persists on both sides of the road, but obviously not above the ground within the roadway.
Bonus question: Is there some sort of check to see if lines of any sort cross each other? I'd like to run a check and verify that none of my geology crosses over the surface line in any location.
Thanks
