In order to provide a useful test set of data, the ONSWG members, and other organizations, have provided a set of example files that demonstrate the behavior of the BAG file in practice. The following data is available for use in testing, but should not be used for navigation, or other purposes.

File Description
H12617_MB_1m_MLLW_1of2.bag High-resolution (1m) BAG from NOAA survey H12617 (Port of Long Beach). See the NCEI Survey Record for more details, metadata, reports, etc.
H12617_MB_2m_MLLW_2of2.bag High-resolution (2m) BAG from NOAA survey H12617 (Port of Long Beach). See the NCEI Survey Record for more details, metadata, reports, etc.
H12617_MB_2m_MLLW_Combined.bag High-resolution (2m) Composite BAG from NOAA survey H12617 (Port of Long Beach). See the NCEI Survey Record for more details, metadata, reports, etc.
H13071_MB_VR_Ellipsoid.bag Variable resolution BAG from NOAA survey H13071 (Yakutat Bay) with ellipsoid heights. See the NCEI Survey Record for more details, metadata, reports, etc.
H13071_MB_VR_MLLW.bag Variable resolution BAG from NOAA survey H13071 (Yakutat Bay) with depths to mean lower low water datum. See the NCEI Survey Record for more details, metadata, reports, etc.
