Updating mm3d Hydrographic, Datacore and C-MAP Charts – How it is Done

Many of you have questions about updates of nautical charts. We will try to explain here how it works, the relationship between MapMedia and data suppliers such as Jeppesen (C-MAP charts) or Navionics (Datacore charts) and also answer the question of who does what.

MapMedia works with various vendors such as Jeppesen and Navionics, as well as national Hydrographic Services.

MapMediaC-MAP: chart data providers for MapMedia Navionics: chart data providers for MapMedia

MapMedia does not correct the C-MAP and Datacore nautical charts as this is done by Jeppesen and Navionics before we receive their data.

MapMedia then converts integrates their charts into our proprietary mm3d format.

How do nautical chart data providers work? How do they get chart corrections to you?

Providers that supply us with chart data are constantly working on improvements, corrections and updates to their entire chart portfolio (like C-MAP and Datacore).

This can be done either by carrying out surveys in the field, through private partners or via Hydrographic Services. This is a non-stop job and requires substantial resources for these investigations and verifications.

However, when Jeppesen and Navionics release an updated version of their C-MAP or Datacore charts, that does not mean that they have re-surveyed the entire chart area, corrected all mistakes and have integrated all marinas worldwide. Of course everyone would like this to be the case but it is not realistic.

Example of a new vs. old Navionics chart

Providers can focus on a particular area, e.g. improving European Rivers, or the Caribbean etc. In this case a special effort will be made in these regions, so that there is be a greater chance that everything will be corrected, but once again, this is not a certainty if they did not have enough information beforehand.

It is impossible for anyone to be aware of every single navigation change or new marina worldwide comprehensively and all at the same time.

There are still some nautical charts that have not been updated in a couple of years. When you see a chart that is for example from 2004 in the MaxSea product list, this date has been directly extracted from the C-MAP (Jeppesen) or Datacore (Navionics) database. It does not mean that MapMedia is using an old chart, this is impossible.

The same goes for raster charts and this update lag is certainly more prominent with Hydrographic Services as the frequency of their chart updates is quite slow. In fact they are less reactive when it comes to the integration of new marinas. Editions and revision dates are generally older.

This however, does not apply to all Hydrographic Services and the SHOM in France offers very good charts for our country as is the case with the biggest Hydrographic Services in their own countries.

Users are also a good source of information. Their comments and critiques are used to improve product quality.

Each time as Anomaly Report is sent to MapMedia via the form on our website, we check it, analyse it and we pass it on to the supplier who produces data for this region.

In turn, the supplier verifies and analyses the problem, and if the suggestion is confirmed, they correct their nautical charts or tell us if the correction is planned for the next version. We then inform the customer who reported the anomaly.

When we receive their updated chart data, we can begin the job of integrating and converting the data into our mm3d format.

MapMedia releases a new version of each chart zone once a year.

It is therefore possible that there is a maximum difference of one version between a MapMedia and chart supplier version during this time.

The quality of charts and user safety is a priority for MapMedia and for all of our chart suppliers.

We try to continuously improve and evolve produts in order to satisfy your needs.

Please continue to keep us updated on any nautical chart problems you encounter. We thank you for your contributions!

Understanding TIMEZERO nautical chart references

If you’ve ever wondered what is the logic behind the chart references found on our online nautical chart catalogue, here’s the answer.

All our charts present the same information when you make a search on our online nautical chart catalogue: name of the zone (Baltic Sea and Denmark in the example below), number of files that you must download in order to install the chart (8 in the example) and chart reference (WVJENM299MAP13.1):

Timezero chart files download

If you already have the chart reference, you can type it in the search bar (green rectangle in the image above). If you put at least 3 characters, our online nautical chart catalogue will display all the chart zones that start with that 3 characters, that’s called stemming.

chart catalog search

But be careful, old versions of some chart zones may have a different syntax.

Take the UK-Ireland Raster chart for example:

  • First version reference was R28P-MAP/01
  • Second version WR28MAP2.1
  • Latest version WRMEW28MAP7.1

TIMEZERO online nautical chart catalogue only displays the latest version of all charts, so if you try to find your old UK-Ireland chart by typing “R28P-MAP/01″ you’ll never find it!

Here’s how TIMEZERO charts are structured:

MaxSea zone naming

SIZE = W wide or MW MegaWide (do you know the difference?)

TYPE = V vector or R raster (an old and interesting debate among sailors)

PROVIDER = M MapMedia  J C-MAP (previously by Jeppesen)  N Navionics  S S-57

REGION CODE = first 2 characters

AF Africa

AN Asia North

AS Asia South

AU Australia

EM Europe Mediterranean

EN Europe North

EW Europe West

IN Indian Ocean

ME Middle East

NA North America

SA South America

PC Pacific Ocean

CODE NUMBER = 000

To find a chart zone in our website, you have 3 options:

  • Use the filters on the left side of the online nautical chart catalogue
  • Type the chart’s reference in the search bar of the catalogue
  • Check our charts list which is categorized by region, type, size, provider and name

Now, if you still don’t find what you’re looking for, try TIMEZERO search bar located at the  top-right corner across the entire website:

search bar mytimezero.com

Finally, take the time to read these few tips on how to choose the best nautical chart for you, it can help you make a decision!
