Shape file with Z and M,

[JamalNUMAN]

Shape file with Z and M,

I couldn???t figure out the distinction between having point shape file, pointZ and PointM.

What is the impact of these shape files as points are captured from the field?

Thank you

Best

Hi Jamal,

A quick answer to your question is that Z-Values (PointZ) have the ability to store elevation (such as GPS height) along with the default X,Y coordinates whereas M-Values allow the ability to store linear measurements (such as offsets within ArcPad). A few links below discuss these options a bit more in depth.

Working with offsets
GPS Height

Feature class basics (under the 'Vertical measurements using z-values' and 'Linear measurements using m-values' sections)

Hope this helps.

Many thanks Luke for the help.

I aimed at creating a shape file that stores XY and Z as points are captured from the ground. This is why I selected the pointZ.

At the end, I tried to open the pointz shape file from the ArcMap but it appears no field that stores the elevation values.

What might be the issue here?

Enabling the z-value as a shape file is created

• allows collecting the Z (elevation) when adding a shape file in an application (like ArcPad) installed in GPS device,
• allows adding the Z value through the “edit sketch properties” in the ArcMap

Hola Jamal,

I wanted to add my two cents to your post, and hopefully this applet will assist you and make things easier for you. Since I see you are looking to capture Z & M values for your data, here is a ArcScript that may make things easier for you in your workflow. This is not written by Esri or supported by us (Support Services/Esri) but we do post items that may assist our customers.

Good Luck!

Gracias, Jamal!

Thanks Juan,

My issue here is how to stick the Z-value in the attribute table in case the Z-value is set to be enabled. The XY coordinates can be calculated using the “add xy coordinates” tool but how about the z value? How it can be incorporated in the attribute table as a field?

the help topic is useful

It works fine

[DanPatterson_Retired]

Yes, that is what it said...but only for ZM enabled files

Thanks Dan.
