We were asked to survey some sections on a road where overhead signs need to go. They shot a series of points in a straight line and want me to create a section from them. So I am able to use Surface to Geometry to get a alignment that I can also plot in a profile window and make it look like a cross section. But I am also trying to get a label at each point. They shoot the points as PGL and use an ST to begin each section/profile. I tried dual coding the points with additional alpha codes to pick up edge of road and top of bank, etc. But it seems like the dual codes did not create a bunch of single point features which meant I could not project feature points to the profile and annotate them.
Is this a WAD?
How can I create a linear feature and get the dual coded random points from what are usually linear features and have them as separate features in the DTM?
Hello Caddcop,
I see there has been a defect logged for the Survey Data to Geometry command not holding the dual codes, D-47725. This issue has been submitted to development and is under review.
Hi caddcop,
Might need an example FWD/XIN here. I tested real quick with three points coded as follows:
1 - TC ST CP
2 - TC SP
3 - TC CP
When I ran Survey Data to Surface, I got three features, TC, CP and SP. TC had a line of 3 points, CP had to points, and SP had one. When I ran Survey Data to Geometry, I got one alignment, TC, and 6 cogo points.
Thanks,
Kevin
After further review, this defect does not specifically match the scenario you have mentioned. Please provide us with an example dataset and a more detailed description of what you want as a desired output.
When I wrote Survey to surface, sometimes the points would get written as features and other times they were missing. But when they were written - they were listed in the Feature Properties dialog boxes with no description (and possibly style.)
And, I could not select them in the list - the bottom area where it should populate with the selected feature information, would show only the features that came across normally. If I pressed the OK button and closed the dialog box, when I reopened it, the problem features would be missing.
I was able to write them to Geometry and then use the import surface from geometry tool and then I was able to annotate them in my profile displays.
The only way I was getting these single point linear features into a surface was by adding an ST to every shot so that it created a new feature every shot.

After reviewing your dataset, I was able to export the data to a surface with the Survey Data to Surface. I looked at point 2522 and saw that the PGL JW features were created in the surface. Instead of having an individual random feature (point) for each JW object, one random feature that held all the JW points was found. This is actually WAD (working as design). Then, I ran the Survey Data to Geometry and saw the individual geometry points created.
Were you wanting an option in the Survey Data to Surface command dialog that appears in the Import Surface Advance below?
This potentially will allow you to specify how the features are created for random points. Note, all the points were still found in our scenario they were just lumped into one random feature instead of individual random features.
