TZ MAPS: The Future of Nautical Charts

For centuries, navigators sailed with help from the stars, but most importantly, paper charts. They were the only way to plan and follow a safe route. But today, many skippers are moving away from paper charts and going digital—many of them choosing TZ MAPS.

This post explains why. It shows how you can try TZ MAPS yourself with a free 7-day trial. The trial is available in the TZ iBoat boating app for iOS.

What’s So Great About Paper Charts?

Paper charts aren’t “wrong” or “outdated.” They are a reliable method of navigation and still offer real benefits to navigators, like:

  • Not needing any batteries or software to work
  • An easy-to-use “big picture” overview of your area
  • Serving as a solid backup if your electronics fail
  • That sense of nostalgia for the way things used to be

If you enjoy plotting with a pencil, paper charts can still be part of your navigation setup. But fewer and fewer navigators are using paper charts as their primary navigation tool, and here’s why.

Why Are Navigators Going Digital?

Put simply, modern boating has changed a lot. We move between areas more often. Coastlines, buoys, and depths are updated more regularly. We expect fast answers to questions like: “How far?” “How long?”, and “How deep?”.

With paper charts, this can create real problems. Updates are slow and manual. You need several charts to cover even a modest distance. There’s no GPS position on the paper. Nighttime or bad weather can make small details hard to read. And in many parts of the world, paper charts are slowly being phased out.

So, What Is TZ MAPS and Why Is It So Popular?

TZ MAPS is the next generation of nautical charts from TIMEZERO. TZ MAPS offers great value. It includes multiple chart formats. It also has advanced features and the latest data. TZ MAPS includes:

  • Raster charts – digital versions of official paper charts from hydrographic offices, with the same familiar look and symbols
  • Vector charts – modern, interactive charts where you can zoom and tap features for more information
  • Detailed land information – roads, coastlines, and landmarks that help you recognize what you see around you
  • High-resolution satellite photos – to better understand harbors, anchorages, and your surroundings
  • High-resolution BathyVision – very detailed depth contours that reveal underwater structures and topography

All of this is packaged as a single TZ MAPS area. You don’t have to choose between raster, vector, or bathymetry. When that data exists for your area, you get it all.

How Do I Get TZ MAPS?

Easy! TZ MAPS is available on all TIMEZERO software. The most affordable option is TZ iBoat, TIMEZERO’s marine navigation app for iPhone and iPad.

TZ iBoat transforms your device into a comprehensive navigation system, that rivals even some of the best systems out there. By accessing TZ MAPS via your TZ iBoat app, you’ll have everything you need for both fun and serious navigation. That means charts, weather forecasts, GPS, Route Assist, and a whole lot more!

In short, TZ MAPS provides the chart data, and TZ iBoat provides the interface that brings it to life.

How Does TZ MAPS Compare?

Here’s a simple comparison to make the differences clear.

FeaturePaper ChartsTZ MAPS
Continuous UpdatesNoYes
Multiple FormatsRasterRaster, Vector, Bathymetry
InteractiveNoYes
Mooring AssistanceNoYes
Route AssistNoYes
Estimated DistanceNoYes
GPSNoYes
Community Data SharingNoYes

Still Not Convinced?

How about this? Paper charts can be expensive, but TZ MAPS on TZ iBoat offers a different approach: you can use a device that you already own; you pay an affordable subscription for your TZ MAPS area—which are always up-to-date—instead of buying stacks of individual charts; and, you can try TZ MAPS free for 7 days before spending a single cent.

That free trial is a great opportunity to navigate your usual area and plan a real trip to see if you like it, with zero consequences. Now to the important question…

Do You Still Need Paper Charts?

Many experienced skippers choose a hybrid approach: TZ MAPS + TZ iBoat as their primary, day-to-day navigation tool, and paper charts as a backup—especially for longer trips or remote navigation.

This way, you get the best of both worlds: the speed, clarity, and power of modern digital charts, and the comfort of knowing you have a usable backup if something goes wrong.

So… Are You Ready to Try TZ MAPS Yourself?

You don’t have to guess whether TZ MAPS is right for you—you can test it on your own boat, in your own waters. Just:

  1. Download TZ iBoat from the App Store on your iPhone or iPad
  2. Open the app and select the TZ MAPS area that covers where you usually sail or cruise
  3. Start your 7-day free trial
  4. Plan a simple day trip and follow it with TZ MAPS on the water

You’ll see the difference instantly: cleaner charts, easy planning, and more awareness and peace of mind.

Paper charts had their golden age. Now it’s time for TZ MAPS. Enjoy the next chapter of navigation.

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.

Navionics nautical chart
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.

SHOM logo – the French Hydrographic Office

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!
