1. vb. [Geophysics]

To annotate a map or other display with data at the appropriate location. For example, geologists post formation tops on well logs, isopach maps and seismic profiles. Geophysicists post velocity values and traveltimes on maps before contouring. Engineers contour maps posted with pressure or production data. Posting can become an iterative process as new data become available and interpretations are updated.
