Minor changes, i.e. informative and/or already implemented in tools/versions currently in use. For NOAA ISD, unless notified otherwise by the HSD/NSD project manager, these changes are applicable as of the date of publication.
- 4.2 Raw Data Submission
- Added note (in parenthesis) to clarify where water column data (if submitted) should be located in the raw data submission.
- 6.1 File Formats
- Added text to make explicit additional BAG requirements:
- Must contain all the critical components of the BAG structure as defined by ONSWG.
- Elevation and uncertainty layers must have values and must not be composed entirely of NaN.
- The uncertainty layer must only contain positive values and no zeros.
-
Every node with a value in the elevation layer must have an associated value in the uncertainty layer, and every node with a value in the uncertainty layer must have an associated value in the elevation layer.*
-
VR BAGs must not have more than 10,000,000 refinement grids.*
- 6.3 Required Metadata
- Added text to make explicit additional BAG metadata requirements:
-
BAG 2.0+ submissions must have the coordinate reference system as defined in CRS. For BAG versions prior to 2.0, the spatial reference system must be projected and the vertical datum must be defined per the project CRS.*
-
All BAGs submitted must also include the creation date, and the survey start and end dates.*
- 6.4 Resolution
- To make it explicit that grids with heights must not be cut-off at 0 meters depth, edited Table 6.4.2 General 1 Minimum Required Grid Resolution so that grids of 1m resolution must include depths less than zero (if present).
- 6.5 Data Gaps
-
For improved clarity and understanding of grid holiday definitions, edited text and added Table 6.5.0 Holiday Dimensions per Minimum Required Grid Resolution to show holiday sizes in meters.*
- 14.1 Report of Survey
-
Added requirement that the reports required for submission must be combined, printed to PDF, and digitally signed.*
- 14.5 Seep and Pipeline Reports
-
Added requirement that all uncharted, non-dangerous pipeline reports sent to the Marine Chart Division Nautical Data Branch:
-
Have a subject line as a <registry number> Non-Dangerous Pipeline Submission ##, to clearly differentiate it from a DTON submission.*
-
Must be delineated as PIPSOL line objects.*
- 14.6 Potentially Sensitive Data Findings
-
Added requirement that if there were no potentially sensitive data findings identified:
-
An email must still be sent to indicate so.*
-
The date the email was sent must be listed in the Supplementals section of the Report of Survey with a comment that none were found.*
- 15.1 Weekly Progress Reports
-
Edited so that the coverage grid of GeoTIFF must be submitted to the project CRS.*
- 15.3 Survey Outline
-
Edited so that the final survey outline must be submitted in GeoJSON format, in unprojected WGS84, and attributed with the Survey Unique ID and area in square nautical miles.*
-
Removed all requirements for submitting the survey outline as a Geopackage or Shapefile, and removed all associated attribution requirements.*
-
Updated the email address where survey outlines must be submitted to.*
- 16.1 Folder Structure
-
Clarified the syntax requirement for Project Unique ID as OPR/S-X###-<KR or NOAA field unit code>-##.*
- 16.2 Naming Conventions
-
Added requirement that the Survey Metadata XML and any report images used must be included for submission as a compressed file.*
-
Added new required deliverable formats:
-
<Survey Unique ID>_Outline.GeoJSON*
-
<Survey Unique ID>_Survey_Metadata.zip*
-
<Survey Unique ID>_Survey_Metadata.pdf*
-
Updated the naming convention of the WKT file.*
- 17.5 Other Common Features by Acronym
- Added requirement that permitted features (e.g. dumping grounds and fish havens) must not be submitted with edited geometry (i.e. descrp = "Update") in order to encompass uncharted obstructions that reside just outside of their boundaries, and that the uncharted obstructions, if warranted, must be submitted as new obstructions (i.e. descrp = "New").
- Added PIPSOL line objects to the table of additional features with conditional attribution to describe the category of pipeline/pipe.
- Removed M_COVR (and associated attribution requirements) from the table to additional features.
* For NOAA ISD only.
