| GGB11 | GEBCO_2019_source_data_type_11 | Multibeam - depth value collected by a multibeam echo-sounder. | 2019-03-15 |
| GGB13 | GEBCO_2019_source_data_type_13 | Isolated sounding - depth value that is not part of a regular survey or trackline. | 2019-03-15 |
| GGB14 | GEBCO_2019_source_data_type_14 | ENC sounding - depth value extracted from an Electronic Navigation Chart (ENC). | 2019-03-15 |
| GGB15 | GEBCO_2019_source_data_type_15 | Interpolated based on a computer algorithm - depth value is an interpolated value based on a computer algorithm. | 2019-03-15 |
| GGB16 | GEBCO_2019_source_data_type_16 | Digital bathymetric contours from charts - depth value taken from a bathymetric contour data set. | 2019-03-15 |
| GGB17 | GEBCO_2019_source_data_type_17 | Digital bathymetric contours from ENCs - depth value taken from bathymetric contours from an Electronic Navigation Chart (ENC). | 2019-03-15 |
| GGB18 | GEBCO_2019_source_data_type_18 | Pre-generated grid - depth value is taken from a pre-generated grid that is based on mixed source data types, e.g. single beam, multibeam, interpolation etc. | 2019-03-15 |
| GGB19 | GEBCO_2019_source_data_type_19 | Unknown source - depth value from an unknown source. | 2019-03-15 |
| GGB20 | GEBCO_2019_source_data_type_20 | Steering points - depth value used to constrain the grid in areas of poor data coverage. | 2019-03-15 |
| GGB21 | GEBCO_2019_source_data_type_21 | LiDAR - depth derived from a bathymetric LiDAR sensor. | 2019-03-15 |
| GGB22 | GEBCO_2019_source_data_type_22 | Bathymetric sounding - depth value at this location is constrained by bathymetric sounding(s) from the SRTM15_plus data set (https://topex.ucsd.edu/WWW_html/srtm30_plus.html). | 2019-03-15 |
| GGB23 | GEBCO_2019_source_data_type_23 | Pre-generated grid - depth value is based on the GEBCO_08 Grid. This data set is a global grid at 30 arc-seconds. It was largely generated from a data base of ship-track soundings with interpolation between soundings guided by satellite-derived gravity data. | 2019-03-26 |
