A dense receiver grid seismic project without receiver point surveying, an example from Romania

Given the prohibitive surveying duration of a dense receiver nodes grid on a seismic project in Romania, a new methodology was developed to layout the receiver nodes and then extract their coordinates from the internal GPS records. Coordinates accuracy was further enhanced with post-processing of GPS information combined with a LiDAR elevation model. Restrictions on receiver count associated to surveying is thus lifted and allows for the full use of dense receiver grids in a forested environment.
