Coordinate datum code
rrc.lat_lon_datum
Which datum the coordinates on a completion packet were surveyed on. Ignoring this is worth up to about 200 metres of error in West Texas. The pipeline that loads this data resolves the code on the way in, so the warehouse column holds the text below rather than the raw RRC code. Both are recorded here so the original filing can be read either way.
