I have some topo drawings (contours with Z elevations) and am trying to create lines representing where we did our field work. I then want to extract X, Y & Z coordinates of points along those lines (either where they cross the contour lines or at regular intervals along the lines that I create). I can create surface(s) of the topo that I have, but my questions are what kind of lines would be the best to use to represent our lines of field work (3D poly lines, feature lines, or alignments) and once I get those laid in, how do I extract the XYZ info into a text format of some kind (excel, csv, etc.)?
Any help would be appreciated.
I suggest drawing your lines as polylines. Next use the Map Cleanup tool to break them where they cross the contours and rejoin them using the Dissolve Pseudo option in the cleanup tool settings. This will result in polylines with vertices at each contour. Next create COGO points on the polylines either at a desired interval or at the vertices using the point creation tools. Set the elevations of the points from the surface and export them to a file.
