HP-SMI_surveyor Posted June 29, 2015 Share Posted June 29, 2015 Hey everyone, I have 2 surfaces, a pre-dredge and then a year later another hydro survey was done. I've got all the points brought in and created point groups, boundaries, and surfaces. The changes in the 2 surfaces are very minor and the client is only wanting to see existing contours and some shading/hatching where the elevations have differed. Any help would be greatly appreciated! Quote Link to comment Share on other sites More sharing options...
Tyke Posted June 29, 2015 Share Posted June 29, 2015 Create a differential DTM, subtract the latest from the first. Quote Link to comment Share on other sites More sharing options...
