The curvature of the earth into consideration. This survey covers large areas of land and provides a high level of accuracies. It also provides a series of control points across the Earth’s surface that makes accurate plane surveys possible.
With the introduction of the Global Navigation Satellite Systems (GNSS), we have been able to conduct this type of survey using geodetic receivers. This has been achieved by doing static observations for long durations and processing using a GNSS software.
