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Paper charts aren’t “wrong” or “outdated.”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.

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.

Marine chart data treatment

Benefitting from 18 years’ experience in the field of cartography, MapMedia selects the best marine charts available, based on several different criteria: coverage, reliability, level of detail and the date of last update.

MapMedia works with Hydrographic Offices all around the world, as well as with private providers who have demonstrated their reliability and professionalism over many years.

Different marine chart sources

Choosing a local supplier is often the most appropriate option due to their knowledge and expertise in that region. MapMedia therefore consists of a very large marine cartography library, sourced from multiple different vendors, which acts as a very strong basis to start from.

The first stage of production is to create a large digital database in order to make the most of the compiled information.

Compilation of marine charts

There are several forms of delivery media for Raster marine charts, whether paper or digital. The important step of scanning the charts and entering data is required. The title of the chart, the scale, the date of issue, date of revision … all make up what we call meta info.

This information will be available later for MaxSea and Nobeltec software users as well as for users of Furuno products. This information is integrated within digital and vector maps.

The second step involves the geo-referencing and compilation of these marine charts. This process is what allows the chart to be well-positioned in relation to the GPS. Particular attention is always given to this crucial step, to ensure the safety of users.

Division in marine chart zonesThe third step is the conversion of all the data into our own proprietary format called mm3d. This format is optimized for and exclusive to MaxSea marine navigation software and related products.

Again, during this third step, stringent controls are in place in order to ensure the reliability of the finished product. Once this work is completed and validated, the final step may begin: the division of the marine chart into “zones” that will be available to users.

A whole series of tests are then carried out on each product to ensure the reliability, consistency and security of data used in the chart. These marine charts are available for download through our online nautical chart catalog.

The Life Cycle of a Hydrographic Marine Chart

Hydrographic charts are an essential source of data for MaxSea marine charts in order to guarantee the quality of this basic onboard tool for safe sailing while at sea.

Did you ever wonder how MapMedia marine charts are produced? Although the charts are edited by MapMedia, this company uses hydrographic charts collected and then updated by hydrographic offices all around the world. Here, we explain the steps of this process.

To draw up a chart, first we must compile data, edit it and then keep it continuously updated.

The data collection

The hydrographic office first acquires bathymetric, topographic and sedimentological surveys as well as satellite imagery and any additional data needed.

Production of the chart

Once all this data has been compiled and verified, a paper chart is drawn up, following very precise specifications in order to comply with sailing requirements in each specific area.  All the necessary information for sailing and safety are provided on the paper chart. The chart must be both precise and easy to read so that you can sail safely.

This first date of publication is always included on the hydrographic chart. We have included images from the French Hydrographic Office to to explain each point in this post.

Chart Updates

Every week, minor or major corrections are reported on the hydrographic chart and then released via the « Groupe d’Avis aux Navigateurs GAN » or “Notice to Mariners – NTM”.

In the case of minor corrections that are not essential for sailor safety, the marine chart is printed again. The date of this new print is mentioned on the chart. A chart can also be printed again if out of stock. The date of the reprint is mentioned on the chart.

When major modifications occur, the hydrographic chart is reprinted. A new publication number and date are added to the chart:

A hydrographic chart publication number and date

A hydrographic chart in Raster format from the SHOM

New chart  SHOM N° 7428

MapMedia compares marine charts and different catalogues and selects the best chart for a specific location in order to provide the most reliable information for safe sailing.
