INFOMAR Survey Data Download

Open Download Site

The Interactive Web Data Delivery System (IWDDS), was developed by Intrepid Geophysics of Australia and is hosted by the GSI. It allows users to browse a catalogue of all the available data and to then pull
their own raw data selections onto their own machines. Data such as bathymetry and backscatter grids, ascii files, fledermaus scenes, google .kmzs and leg reports for all INSS and INFOMAR surveys can be downloaded.

The site contains a very basic map covering the entire Irish land and sea area. A user can choose their area of interest by coordinate map extent, or by map number if they already know the area well, or by
drawing a map-extent box on the map.

If a user is unsure with regards to their area of interest they may prefer to use the INFOMAR webmapping viewer to locate the data. The viewer allows the user to choose by survey leg for example.

When a user is happy with their selected area, they then proceed to the download page. The user then selects a data type (vector, gridded, report, fledermaus, google), a region (onshore or offshore) and a theme (bathymetry, backscatter, bedrock etc).


Depending on the user’s chosen criteria and area of interest, the system then returns a listing of all of the data it contains of that type within that area. The user can browse through and preview this listing.


After making selections for parts or all of the data listed, a user submits their data request. The request gets queued for action by the system. When the request has been acted upon and completed by the system, the IWDDS then emails the user who made the request, giving them a secure FTP link to download the data.

Additional features such as end user map creation on the fly and end user on the fly gridding of the XYZ datasets is also available.

INFOMAR raw Multibeam Bathymetry Data Download from NOAA

Open Download Site

INFOMAR sends raw multibeam bathymetry data to NOAA's National Geophysical Data Center (NGDC). NGDC is the US national archive for multibeam bathymetric data and presently holds over 15.7 million nautical miles of ship tracklines (1187 surveys) received from sources worldwide. In addition to deepwater data, the multibeam database also includes hydrographic multibeam survey data from NOAA's National Ocean Service (NOS).

Locating and Downloading Data:

Multibeam bathymetric data at NGDC can now be selected via an interactive map (ArcGIS) Web interface. Data selections are downloadable for free.

Frequently Asked Questions:

Why can't ESRI read the data I downloaded?
You probably downloaded the raw multibeam files. These can't be read by ESRI. You can go to autochart (http://www.ngdc.noaa.gov/autochart/) which will allow you to create a NetCDF binary grid of the data in your area of interest which ESRI can read.

What other programs can I use to read raw multibeam data?
Some of the products known to read raw multibeam data are: MB-System, CARIS, and Fledermaus. This list is provided for information only, NGDC does not recommend or endorse external products.

Webmapping Viewer

Click Here to open the Webmapping Viewer in a new window

The webmapping viewer has been designed to display the large raster datasets. This includes bathymetry (water depth), seabed classification, backscatter and shaded relief datasets.

Bathymetry grids are scaled and you will see a higher resolution as you zoom into the map. The resolution varies between 2 - 100m resolution. There is a variation in the standard of the data used in the viewer, these are divided into surveys that meet IHO standards and surveys that don’t meet IHO standards. Both layers can be viewed in the Survey Coverage layer.

Data from associated projects/organisations is also used within the viewer and again you can see the name of the associated organisation or project in the Survey Coverage Layer.

The seabed classification divides the seabed into different sediments types. The resolution varies between 5 - 20m resolution.

The backscatter images can be used to interpret the composition of the seafloor. High backscatter is shown as dark areas and represents rock outcrops and the soft sediments are lighter grey areas. The resolution varies between 2 - 20m resolution.

The shaded relief images are created by artificially placing a sun at an angle to the terrain model created from the XYZ values to give light and shade to the terrain and are excellent for showing the texture and general composition be it sediment or rock or the seafloor. The resolution varies between 2 - 100m resolution.

Vector datasets are also available including shipwrecks, survey areas, tracklines and grab sample data. 

The ARCGIS REST service link for this viewer is

http://maps.marine.ie/arcgis/rest/services/Infomar

You can use the link to view all of our data in the ArcGIS desktop software.

Within the service there are two image services available (Bathy_All_Surveys and Bathy_CoastalSurveys) which enable users to view and identify values in the bathymetry data.

Open ArcCatalog. Go to GIS Servers. Add ArcGIS Server. Use GIS Services. Paste in the link.

Dynamic Web Mapping Viewer

INFOMAR Dynamic Web Mapping Viewer allows users to manipulate and analyse the bathymetry data within the browser. View the INFOMAR Dynamic Web Mapping Viewer Quick Guide on YouTube https://youtu.be/A54mWGW-egw

The viewer enables dynamic rendering of the bathymetry data so it can be manipulated to best suit each individuals requirements.

It is also possible to extract water depths for specific points and carry out basic analysis of the bathymetry data such as slope and aspect analysis....Open Viewer

Global Shaded Relief Bathymetry - ESRI Ocean Basemap

INFOMAR data included in dataset

http://services.arcgisonline.com/ArcGIS/rest/services

INFOMAR bathymetry has been incorporated into ESRI's Ocean Basemap. The Ocean Basemap is now available as a cached map service in ArcGIS Online. This map service is designed to be used as a basemap by marine GIS professionals and as a reference map by anyone interested in ocean data. The basemap includes bathymetry, marine water body names, undersea feature names, and derived depth values in meters.

You can view the basemap using the ArcGIS.com online viewer or ArcGIS Explorer online

An ESRI layer file can also be downloaded and used in ArcGIS Desktop. Click here
