Method and system for evaluating geophysical survey data

A method for evaluating geophysical measurements comprising:

• receiving geophysical data recorded from a geophysical survey flight, wherein the geophysical data is recorded from a series of flight paths covering a survey areas and wherein the geophysical data includes full-tensor gravity gradient data;
• selecting a first set of data from the geophysical data, wherein the first set of data is recorded from a first flight path;
• generating a grid using neighboring geophysical data from the geophysical data, wherein the neighboring geophysical data is recorded from flight paths that neighbor the first flight path;
• and
• comparing the first set of data and the grid to estimate a quality of the first set of data.

A method for evaluating geophysical measurements comprising:

• recording geophysical data during a geophysical survey flight, wherein the geophysical survey flight comprises a series of flight paths covering a survey area, and wherein the geophysical data includes full-tensor gravity gradient data;
• and
• during the geophysical survey flight, evaluating the geophysical data to estimate a quality of the geophysical data by:
• selecting a first set of data from the geophysical data, wherein the first set of data is recorded from a first flight path, the first flight path being one of the series of flight paths;
• generating a grid using neighboring geophysical data from the geophysical data, wherein the neighboring geophysical data is recorded from flight paths that neighbor the first flight path;
• and
• determining a standard deviation between the first set of data and the grid to estimate a quality of the first set of data.
