ProjectZ runs, but doesn't actually convert elevations #77

Closed aaronpaBMI closed 5 years ago

aaronpaBMI commented 5 years ago

I have been trying to figure out if there is some kind of issue with my inputs for this tool. I am able to run it successfully, but the output Z value has not been changed. The output values are exactly the same as the input values. I have attached an image of the inputs. Maybe there is something that I'm not doing correctly that you'll be able to see. I am using ArcGIS Pro 2.3.2. Any insight as to what is happening?

Thanks!

I have the same issue. I can run the tool successfully; however, my z value does not change.

Danik-B commented 5 years ago

I'm getting the same result as well. No change in z values.

@aaronpaBMI @michellejakson @Danik-B

Thank you for the feedback. I just wanted to confirm the 'Z values' you're referring to. Are you referring to the values in the 'Altitude' field or in the POINT_Z field for the output feature class?

In the screenshot at the top (@aaronpaBMI), I would assume the 'Z' value in your input feature class would equate to the 'Altitude' metadata field (ESRIGNSS_ALTITUDE)?

What are the datums (horizontal and vertical) you're transforming between?

Thanks

I encountered this issue as well and after reading the documentation more closely I realized it is likely because I have not installed the Coordinate Systems Data files from MyEsri. It might be helpful to add an idiot-proof error trap on this (for folks like me) to prevent use of the tool if the specified vertical transformation file is unavailable (and reference the resolution as well), rather than just running the script without a primary input like the GEOID12B file, in my case.

Hi @LowellMA-stormwater

Thank you for the response and for posting your solution with installing the Coordinate Systems Data. Was the tool working successfully after installing that data?

LowellMA-stormwater commented 5 years ago

Yes, Kevin, this resolved the issue and I now have control points surveyed to within 19 mm using Collector from my iPad. Thanks for your work!

Thank you @LowellMA-stormwater!

We will look into improving the tool's validation to check for the coordinate system data being installed or not.
