        report:  (DQ_AbsoluteExternalPositionalAccuracy)
            nameOfMeasure:  Horizontal Positional Accuracy Report
            evaluationMethodDescription:  Horizontal accuracy varies from source contributor to source contributor. However, horizontal positions are usually taken from topographic maps of the area being surveyed. Accuracy may range up to +/- 100 feet.

        report:  (DQ_AbsoluteExternalPositionalAccuracy)
            nameOfMeasure:  Vertical Positional Accuracy Report
            evaluationMethodDescription:  Vertical accuracy varies from source contributor to source contributor. However, vertical positions are usually taken from topographic maps of the area being surveyed, monumented benchmark locations, or they are determined by the use of the Global Positioning System (GPS). Accuracy may range from meters to centimeters or better.

            nameOfMeasure:  Quantitative Attribute Accuracy Assessment
            measureDescription:  Statistical analysis.
            evaluationMethodDescription:  Gravity data values are the result of the measurement of small variations in the gravitational field of the earth. The magnitudes and ranges of these variations are well known in the potential field discipline.

                    identifier:  meters
                    unitsSystem:  http://www.bipm.org/en/measurement-units/
                  Record:  Variable: the average acceleration on the Earth's surface is about 980 centimeters per second squared, which is equal to 980 gals, but increases by about 1/2 percent from equator to pole.
