I’m Looking for a Vector Marine Chart for Routing Software

Introduction

Are you looking for a vector marine chart for routing software to plan coastal navigation, an offshore passage or an ocean crossing? Vector marine charts are now an essential source of data for many navigation, weather routing and voyage planning software solutions.

Unlike a raster marine chart, which essentially reproduces the image of a paper chart, a vector chart is made up of structured geographic data. Each piece of cartographic information can therefore be identified, interpreted and displayed by the software: soundings, depth contours, lights, buoys, wrecks, channels, regulated areas, ports and other hazards.

Choosing a digital marine chart suitable for routing software therefore requires several criteria to be considered: the geographical area covered, data format, software used, level of detail, source of hydrographic data and update frequency.

What Is a Vector Marine Chart?

A vector marine chart is digital cartography made up of geographic objects rather than a simple image. Each object contains characteristics that can be interpreted by navigation or routing software.

A single chart may contain:

• soundings and depths;

• depth contours;

• shoals and hazards;

• buoys and other navigation marks;

• lights and their characteristics;

• wrecks;

• rocks and underwater or surface obstacles;

• channels and navigable waterways;

• ports and harbour facilities;

• regulated or special areas;

• aids to navigation.

This structure allows software to select, hide or display specific information depending on the zoom level or settings being used.

Vector cartography is therefore particularly useful for software that does more than simply display a chart, but also uses chart data within its navigation or route-planning environment.

Vector Chart vs Raster Chart: What Is the Difference?

The main difference between a vector marine chart and a raster chart lies in the way the cartographic information is stored.

A raster chart is generally a digital image derived from a paper chart or rasterized cartographic data. When it is enlarged significantly, the image will eventually lose sharpness.

A vector chart, on the other hand, is based on geographic objects. The software can therefore manage the different chart elements separately and adapt their display.

For routing software, this difference can be important. The software needs to work with structured geographic data and associate this information with the calculated route, navigation parameters or other information used to plan a voyage.

What Is a Vector Marine Chart Used for in Routing Software?

Routing software is used to prepare and analyse a maritime route according to various parameters. Cartography is therefore one of the fundamental components of this digital environment.

Depending on the software and the available data, a vector marine chart can be used to:

• plan a coastal route;

• plan an ocean crossing;

• identify hazards located near a route;

• display depths and bathymetric contours;

• plan navigation between ports;

• analyse a route before departure;

• combine chart data with weather information;

• perform weather routing;

• prepare offshore navigation;

• compare different route options.

For example, when planning an Atlantic crossing, routing software may use chart data covering the departure area, destination and all the regions crossed along the route. The route can then be analysed together with weather forecasts, wind, swell or currents, depending on the software's capabilities.

Which Vector Charts Are Used by Routing Software?

There is no single vector chart format that is compatible with every routing software solution.

Data may come from official hydrographic offices or specialist digital chart publishers. They may also be distributed according to different standards or proprietary formats.

ENCs, or Electronic Navigational Charts, are an important category of digital vector marine charts. They are produced according to international hydrographic standards and are intended for compatible navigation systems.

ENC data can notably be associated with the S-57 standard and, as digital hydrographic data continues to evolve, with the newer generation of S-100 standards.

It is therefore important not to choose a chart solely according to its geographical coverage. Compatibility with the routing software must also be checked.

How Do You Choose a Vector Marine Chart for Routing Software?

The first criterion is naturally the navigation area. A chart intended for the Mediterranean will not meet the same requirements as one covering the Atlantic, English Channel, North Sea, Caribbean or Pacific Ocean.

You should then check the specifications of the routing software being used.

The main criteria to consider include:

• the navigation or routing software;

• the accepted data format;

• the required geographical area;

• coastal and offshore coverage;

• the level of cartographic detail;

• the source of the data;

• the frequency of updates;

• any licensing or usage conditions;

• compatibility with the computer environment being used.

This verification is particularly important for professional software and specialist maritime routing solutions.

Vector Marine Charts for Coastal Routing

For coastal navigation, the accuracy and level of detail of the chart data are particularly important.

Close to the coast, the software may need to display numerous objects: channels, navigation marks, lights, rocks, wrecks, regulated areas, ports, anchorages and other hazards.

Vector cartography makes it possible to manage this information dynamically and display it according to the selected zoom level.

When planning a route between several ports, the navigator can therefore visualise the coastal areas along the route and check potential hazards or cartographic constraints before defining the itinerary.

Vector Charts for Offshore Routing and Ocean Crossings

For offshore navigation, the requirements are different. The navigator generally needs much wider geographical coverage, allowing a route extending over hundreds or thousands of nautical miles to be planned.

A vector marine chart for ocean routing can be used to:

• plan a transatlantic crossing;

• analyse a route between Europe and the Caribbean;

• plan a passage to the Azores;

• prepare a route towards the Canary Islands or Cape Verde;

• plan a Pacific crossing;

• study a round-the-world route;

• analyse offshore navigation.

In this context, the chart data must cover the entire planned route and remain consistent with the data used by the routing software.

Weather Routing and Marine Cartography

Some software combines marine cartography with weather routing functions.

The principle is to analyse a route while taking into account parameters such as wind, waves, currents or weather forecasts. The marine chart then provides the geographical context in which the route is calculated.

For example, during an Atlantic crossing, routing software may propose different trajectories depending on the expected evolution of weather conditions. The marine chart simultaneously makes it possible to visualise coastlines, islands, maritime areas and geographical constraints associated with the route.

Cartography and weather data therefore fulfil two complementary functions: the chart describes the geographical and hydrographic environment, while weather data is used to analyse expected conditions.

Vector Cartography for Professional Navigation

Vector charts are also used in many professional maritime environments, including merchant shipping, maritime transport, offshore operations, research, maritime services and other activities at sea.

In these contexts, requirements regarding data, formats, updates and compatibility with navigation systems may be considerably more specific than for recreational sailing.

It is particularly important to distinguish chart data intended for routing or voyage planning from chart data meeting the specific requirements of a regulated system such as an ECDIS.

The choice of data must therefore be based on the software being used and the intended navigation purpose.

Why Are Vector Marine Chart Updates Important?

The maritime environment is constantly changing. Navigation marks may be modified, new structures may be built, certain areas may become regulated and hydrographic information may be corrected or supplemented.

Updating digital chart data is therefore an essential part of modern digital navigation.

For routing software, using recent data makes it possible to work with a chart representation that more closely reflects the available hydrographic information.

However, the frequency and method of updates depend on the data provider, format, software and type of licence.

Vector Marine Charts: Mistakes to Avoid

Before choosing digital cartography for routing software, several common mistakes should be avoided.

• Choosing a chart solely according to its geographical area.

• Failing to check compatibility with the software.

• Confusing vector and raster charts.

• Confusing official ENCs with commercial vector chart products.

• Overlooking licensing conditions.

• Failing to check complete coverage of the planned route.

• Ignoring the update frequency.

• Using chart data that is not suitable for the intended purpose.

A chart that theoretically covers a given geographical area is therefore not necessarily compatible with every routing or navigation software solution.

What Type of Navigation Can Vector Marine Charts Be Used For?

Vector charts can meet a wide range of navigation requirements:

• recreational boating;

• cruise planning;

• coastal navigation;

• offshore navigation;

• transatlantic crossings;

• offshore operations;

• weather routing;

• round-the-world voyage planning;

• professional navigation;

• maritime route planning.

The choice always depends on the equipment, software, geographical area and required level of detail.

Why Use Vector Cartography to Plan a Maritime Route?

Vector cartography provides a structured digital representation of the marine environment. Compatible software can manipulate the different chart objects and display them dynamically.

It is particularly suitable when chart data needs to be integrated into a digital route-planning environment rather than simply viewed as an image.

For a navigator preparing a long-distance passage, routing software combining chart data, weather information and navigation parameters can therefore provide a comprehensive voyage-planning environment.

Conclusion

A vector marine chart for routing software should not be selected solely according to its geographical coverage. Data format, software compatibility, chart coverage, level of detail, data source and update procedures are all important criteria to consider.

Whether you are planning coastal navigation, a transatlantic crossing, an ocean passage or professional maritime operations, vector cartography provides compatible software with structured data that can be used to accurately represent the marine environment.
