Create (Interpolate) a terrain profile from GPS (Txt) points

Hey there,
first I wanted to say "hello" as it is my very first thread and I want to apologize in case i chose the wrong sub-forum.
Also my problem might be very easy to solve but im a beginner, so sorry 😉

I have data from a DGPS in a textfile, looking like this:

id_name, x,y,z

GPS_Auto_64265,703719.746,2561495.860,108.817
GPS_Auto_64264,703719.708,2561495.694,108.818
GPS_Auto_64263,703719.651,2561497.727,108.846
GPS_Auto_64262,703717.832,2561499.388,108.907

I can import, but how can i create a profile out of my point data? and prefereably also add a base level?
Thanks a lot,

Basti

Once you have the data in a format where the point name, x, y, z is there then you can import the txt file as an Event Layer and then convert to a point file. With the points(be sure to put in a feature dataset), you can then create your terrain. Generally the workflow is used with LAS/Lidar data and there is a point file spacing associated with that data. You should measure several locations between your points and see if you can determine the average point file spacing. Then you can create the Terrain by right clicking in the feature dataset and then following the prompts after selecting a New > Terrain.
