How can I get elevation data from my ZM Point?

ChristopherClark1 — Mon, 23 Mar 2015 18:07:33 GMT

I have 4 seperate point feature class files. Each one of them has only 1 point. These points were collected with a trimble, and I exported them to shape file then to geodatabase feature class. They do have z value information. I can check te attribute of the point and under the "Shape" column it tells me it is a Point ZM.

I am trying to just get the Z information. I want to get the elevation data for each point. Not sure if I need to convert this point to a 3D point to get this information, or if there is another way.

THANKS!

Have you tried Feature Class Z to ASCII (3D Analyst Tool)?

I have used that tool, and my output is

1 359248.2555 78628.9096 150.5130

I am using HARN state plane south Washington for my projection..

How do I interpret those numbers?

I think I got it, the 3rd value is elevation and is in meters! THANKS!!

First number is your northing, second is your easting, third is elevation value, in whatever unit value your coordinate system is in(you can have HARN State Plane in either meters, international feet, or feet). Check what your linear unit is for your projection and that will tell you what units it is in.

Another option: for features with elevation data (ZM) you can use the Geometry Calculator to fill in a field with the elevation values.
