2.3.4.1. How To Use?

Export elevation values as a point cloud.

  • Select the Grid xyz tab on the bottom of the QC Tools interface.

  • Choose the coordinate reference system that the user would like the file to be exported. The user may keep the original coordinate reference system, convert to Geographic WGS84, or convert to a specific EPSG code using the radio buttons.

  • Choose the Z convention of either Depth (positive down) or Elevation (positive up).

  • The user optionally can choose to truncate the depth after a specific decimal place.

  • The user may also choose the output order of the latitude/northing, longitude/easting, and depth/elevation to suit their needs.

  • In Execution (Fig. 2.73), click Grid XYZ v2.
