Data Retrieval and Management
Frequency of data transfer
Depending on logger type, CSB data will be transferred at varying intervals. For first-generation loggers like the YDVR, the data transfer timing depends on a few variables. First, the amount of onboard storage (SD card size) will determine how much data can b...
Offload mechanisms
The method of retrieving data varies with the type of logger. For first‑generation loggers, or when using a WIBL in a similar mode, data must be retrieved manually by removing the SD card, copying the files, and uploading them to a secure cloud location. This ...
Data Transformation and Submission
WIBL and YDVR data processing
Getting Set Up You will need to install the following programs to run the WIBL processing scripts: Python 3.14: download here. Choose Customize Installation. Under Advanced Options check the box "Add Python to Environmental Variables." [More detailed instr...
Submission of GEOJSON data to the DCDB
All data submitted to the DCDB need to be in .geojson (preferred) or XYZ format and contain appropriate metadata fields. These requirements are outlined in DCDB guidance documents. For WIBL or YDVR data, you will need to upload data periodically. See the WI...
Graphical user interface
As of March 2025, a Graphical User Interface (GUI) is being developed to aid in the processing and submission of CSB data. The GUI should lower the barrier to entry for organizations interested in becoming involved with Seabed 2030, but lacking the time or exp...
Data Extraction and Processing
If your stakeholders would like to see their data for themselves, it may become pertinent that you download and share the data yourself. To do this, you will need to follow the steps outlined in the NCEI/DCDB data extraction section. Once raw data are obtained...
NCEI/DCDB data extraction
Perform the following steps to extract CSB data from the DCDB: Go to the IHO Data Centre for Digital Bathymetry Viewer. Click the IHO DCDB/NOAA NCEI drop down menu, uncheck the ‘Multibeam Surveys’ layer and select the ‘Crowdsourced Bathymetry Files' la...
Pydro tidal corrections
Support Contact: Anthony Klemm, NOAA Office of Coast Survey anthony.r.klemm@noaa.gov Perform the following steps to process CSB data extracted from NCEI/DCDB to correct for tides and data-derived vessel transducer offset values: You will need to download ...
Data Visualization
Tidal-corrected data should be edited using GIS software and uploaded to a central location which can be shared with your stakeholders. This allows you to provide data to participants in the format that best fits their needs. KML files are typically too large ...
ArcGIS: Editing tide-corrected CSB data
For Trusted Nodes that have access to ESRI software licenses, tide-corrected CSB data can be edited and visualized using ArcGIS Pro. 1. Launch ArcGIS Pro and select 'Map' under New Project. Create a name and select a location to save your project. 2. ...
ArcGIS: Generating CSB data shapefiles
This section provides instructions on how to export shapefiles of CSB data for specific participants, or for upload to an ArcGIS Online CSB Data Portal. If your shapefile contains data from multiple participants, you will need to apply a selection query to cr...
QGIS: Editing tide-corrected CSB data
For Trusted Nodes that prefer to use free and open-source GIS software, the following section describes how to edit tide-corrected CSB data using QGIS, and how to export shapefiles of data that can be shared with program participants. Launch QGIS and select...
QGIS: Data visualization
Motivation Some crowdsourced bathymetry participants may have a clear idea of how they intend to use the depth soundings they've collected and what data format best suits that purpose. Others may benefit from a simple tutorial on how to visualize their data u...
Use Cases and Effective Communication
NOAA data scrape
In 2025, NOAA Hydrographic Systems and Technology Branch, in collaboration with University of New Hampshire Center for Coastal and Ocean Mapping, and the IHO Data Center for Digital Bathymetry, began investigating operationalization of CSB data for safety of n...
Tampa Bay community mapping efforts
NOAA’s hydrographic health model is a risk-based framework that evaluates the safety of navigation by combining factors such as ship traffic, records of groundings, the quality and age of existing data, and the rate of seafloor change. The model produces a “hy...
