A common problem that underground surveyors have is how to post process their CMS surveys to make them valid. I have travelled to many sites and seen many different ways of doing this, but the problem remains that some of these CMS surveys are difficult to validate in a timely manner.
We’ve received a recent question from one of our Surpac users about combining DTMs, and I thought I would share this on the blog. The specific query was:
I have 2 DTMs that I want to combine, one represents the surface up to the crest of a pit and the other the floor. When combined, they will represent a pit design with the surface extending away from the pit.
Also, is there a Z factor or vertical exaggeration tool that can be applied temporarily to DTMs?
