This is a Point data set.
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000001. Longitudes are given to the nearest 0.000001. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is D_WGS_1984.
The ellipsoid used is WGS_1984.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257224.

The purpose of these data is to provide the navigation for USGS cruise 2010-033-FA as recorded by CSI LGBX Pro Differential Global Positioning System (DGPS) with HYPACK software. This provides an archive of the original navigation as well as allowing others to reprocess the navigation for their purposes.

The navigation receiver used was a CSI LGBX Pro DGPS2. The accuracy of this system is better than 10 meters.
These files represent all the navigation recorded by the HYPACK software version 10.0.5.31 during USGS cruise 2010-033-FA.
These are the original files recorded by the HYPACK navigation software. No additional checks or corrections have been made to these files. ***Of note, although fathometer data appear to be recorded, use with caution. The values recorded by the $SDDPT string appear to be valid (and associated EC1 values). However, $SDDBT values appear to be bogus - which would included the associated EC1 values. Also, two navigation devices were recorded. Device 0 recorded DGPS and are the valid fixes. Device 1 recorded RTK data and are invalid - only collected for test purposes.
Are there legal restrictions on access or use of the data?
- Access_Constraints: None.
- Use_Constraints:
- The public domain data from the U.S. Government are freely redistributable with proper metadata and source attribution. Please recognize the U.S. Geological Survey as the originator of the dataset.
