i'm trying to convert some *.xyz files into shapefiles but unfortunately it does't work out correctly! I use the tool "ASCII 3D to Feature Class" (ArcMap extension "3D Analyst") because I've read this is a good and easy way to do this. But for some reason the attribute table of the resulting shapefile does not contain the z-values:
This is a problem because I want to generate a DTM out of the shapefiles.
Is there any solution for this? I've tried several options within the tool but without luck.
I don't think it's that important but for your information:
I have two different kind of *.xyz files which I can use representing the same area (2 meter grid width and variable grid width). they are build like this:
variable grid width:
(no header) – (2x space)x-value(4x space)y-value(5x space)z-value
2 meter grid width:
(no header) – (2x space)x-value(2x space)y-value(2x space)z-value

As FelixIP said in the comments, the Z values should be in there: the "Z" in the Shape type of "Multipoint ZM" indicates that your layer is z-enabled, so if you did the conversion from .XYZ to Shapefile correctly, your Z values are in there. It's just that Z values don't show up in a feature's attribute table by default, you need to add them manually. You can use the 3D Analyst Add Z Information tool to do that if you want to check your data, but any of the ESRI tools which operate on Z values should work fine with your shapefile the way it is.
