Import CG-5 Data#

This module imports CG-5 gravimeter data from either a TXT or a XYZ file (as exported by the gravimeter). The user is also expected to input a comma delimited Global Positioning System (GPS) file with Station, Latitude, Longitude and Elevation columns.

The options on the interface are :

  1. Load CG-5 File – Select the file that contains the recorded gravity data.

  2. Load GPS file – Select the GPS CSV file.

  3. Line – Select the column in the GPS file that contains the line number.

  4. Station – Select the column in the GPS file that contains the station number.

  5. Longitude – Select the column in the GPS file that contains the longitude.

  6. Latitude – Select the column in the GPS file that contains the latitude.

  7. Ellipsoid (GPS) Elevation – Select the column in the GPS file that contains the elevation. Elevation must be in metre.

  8. Minimum Base Station Number – All station numbers larger than this are base stations.
