Marine Digimap has updated datasets in its brand new Marine Download facility.  The new interface provides a single place to get both Hydrospatial data and charts. The Hydrospatial data is now the newer Hydrospatial One dataset from SeaZone which also provides access to much higher resolution gridded bathymetry data, one arc second instead of six.  The Charted Raster dataset has been replaced with Hydroview Charts; these are still the same scanned Admiralty Charts though they are much more recent and include some small scale charts covering whole oceans (still not for navigation though!).

Marine Download works in the same way as Data Download, Environment Download and Geology Download; you select your area, pick your products and download the  data. The main difference is with datasets as these don’t all form continuous coverage of the UK Coastal waters. We have therefore included overlays that show where the tiles of each dataset can be found. These are very useful when choosing your data, just open the “Show Grid / Overlay” menu on the right of the map and pick the overlay for the data you are selecting.

Remember there can be a lot of overlap between the Hydroview Charts and also large areas with no data, you will get all the charts that present for the area and scale band that you choose. If there is no data for the area you have selected then you will not be able to add anything to the basket, if you try you will get an error message informing you of the products with no coverage.

For a full description on how to use the new interface, have a look at the help page: How to use Marine Download

The data in Marine Download is broken into three categories, Hydrospatial, Hydroview Charts and Bathymetry. In the Hydrospatial category the same themes as before can be found, the Hydroview Charts are broken up into categories depending on their scale including those extra charts with wider ocean or global extents.

The old interfaces for downloading data, Hydrospatial Download and Charted Raster Download, will be withdrawn in the coming weeks, if you have teaching materials that include them then please update these as soon as possible.

If you have any questions about the new download or the withdrawal of the old interfaces then please get in touch:
