I am trying to generate elevation data along lines and I have followed the process below:
Here is where everything gets messed up. When I do my Join based on the IDs it locating both a start and an end point on the same line with the same distance and is throwing off the tool by giving me an identical elevation. It ends up with my section of 1 intersection of 3 lines looking like this:
Lines
OBJECTID | StartZ | EndZ | START_FID | END_FID |
3 | 181.1 | 181.1 | 4 | 3 |
19 | 199.6 | 199.6 | 19 | 247 |
21 | 171.1 | 171.1 | 3 | 19 |
Start_Point
OBJECTID | ORIG_FID | StartZ |
19 | 19 | 171.1 |
End_Point
OBJECTID | ORIG_FID | StartZ |
3 | 3 | 171.1 |
21 | 3 | 171.1 |
So what I am seeing is that Line 21 is getting both its StartZ and EndZ from the same spatial location even though it should only be getting one or the other. How can I prevent this from happening?
Solved! Go to Solution.
Nevermind. Trying to use old tools to solve this when I can just calculate the z-values right in the field geometry calculation in the attribute table.
