    I can't imagine a GIS application which couldn't read this data, but the procedures to do so would be sufficiently different to make this a score of different questions. Please edit the question to specify the GIS application you want to use, take some effort to start importing the data, and post a specific, focused question (with details of the software, steps taken, and code, if any) if you have difficulty. – Vince Jan 06 '16 at 17:21
  • Thank you. I'm not an expert in this particular (feature) area. – wonder Jan 06 '16 at 17:36

    ArcGIS and QGIS are still two different applications, generating two different answers. You don't need to be an expert to start work. – Vince Jan 06 '16 at 17:56

    You may need to convert the XYZ coordinates, if they're 3D Cartesian, into latitude, longitude, ellipsoidal height, then also convert the ellipsoidal height into geoidal height (aka relative to MSL/geoid). – mkennedy Jan 07 '16 at 00:03
  • Thanks @mkennedy. Could you describe, in this issue, more detail here http://gis.stackexchange.com/questions/175926/convert-xyz-coordinates-to-lon-lat-to-calculate-height-change-gps-time-series-da?lq=1 And as I understand it is impossible to do in QGIS? – wonder Jan 07 '16 at 19:09

Use the Add delimited text tool or Layer/Add layer/Add delimited text from the menu:

enter image description here

This way you get points in QGIS.

  • Thank you very much. Is it possible to calculate the vertical velocity in mm (z coordinates) using QGIS? – wonder Jan 06 '16 at 19:09

    I think first you should create lines from points using a plugin see: http://gis.stackexchange.com/questions/137585/how-to-connect-points-by-lines or http://gis.stackexchange.com/questions/162072/how-connect-points-with-lines-in-qgis. You should copy the time for the start and end point to the line. Finally, using field calculator to calculate speed. It is an idea, I didn't test it :( – Zoltan Jan 07 '16 at 07:28
  • @wonder Loading data and analyzing it are very different questions. Please ask one question at a time, in separate questions, so that answers can be generated for each. – Vince Jan 07 '16 at 11:51
