elevation query

[MarcusHumphrey]

There's a few parts to this question.

How do you get points of a DTM? I managed to get it working by doingrastor to multipoint.

I did try extract value to point before and the DTM havd no features until I did rastor to multipoint.

Is there a quicker way or easier way?

Also how can elevations be added to end points of lines?

The Raster to Point tool is the easiest way to convert a raster to point elevation.  The Extract Values to Points tool will extract values from an underlying elevation raster to an existing points feature class/shapefile.

If you have 3D Analyst, you can use the Interpolate Shape tool to convert your line to 3D based off of an elevation raster.  There is an option within this tool for the interpolation to use the input vertex locations.

Thanks.

I've managed to get the points, but how would be able to select only the points that on the end of lines or closest point? I need to code it in for a new tool, but trying to find the tools that already do it, and looking at how the code is and how it can be altered.

You can extract the endpoints from lines using the Feature Vertices to Points tool.  Choose the option BOTH_ENDS for the Point Type.

I have done that for something else created.

How would I get the elevations of those specific points? There is only elevation on the DTM and got the points from that.
