![]() ![]() ![]() It has the power to show the detail of wrecks, for instance, and in the future this could be enriched with a POI of a photograph showing the boat before it sank – something C-Map has discussed already. ‘There are no obvious benefits to sailors, other than it looks cool,’ Svensson admits. It looks great, and fishermen must be cock-a-hoop, but how useful is this type of digital chart really to sailors? You don’t have to be a fisherman to find this interesting – humans are very curious by nature.’ ‘Reveal is something that anyone can understand – the shallowest part the deepest part. ‘In the end, you can’t see the forest for the trees if we add too much content,’ says C-Map’s Svensson. ‘We have a team of 10 to 20 people around the business handling the quality control and this sets us apart from the competition,’ says Svensson.Įasy Routing is what C-Map calls it automatic route-planning tool, built into its 4D chartsĬalled Reveal, it is almost like a video game. Only then is it made available as community data. The logs are corrected for tidal heights, then compared with other users’ data of the area for continuity. These logs are built from a combination of GPS positions, depth data and the time which is stored by the plotter or phone until it can connect to WiFi ashore. £228 (4D) £155 (Discover) £210 (Reveal) Annual subscription: £34 ($45)Ĭhief among the ways of differentiating the products is the integration of modern sonar logs, which are recorded and uploaded by ordinary boat owners. Where plotters or apps support it, your digital chart can even suggest the best passage plan for you. The result is that sailors can now access very accurate bottom relief contours for most of the UK’s waters, plus embedded photographs, satellite overlays and details of points-of-interest. ‘We want to crowd-source data and enrich the charts with unique content not available anywhere else.’ ‘We’re all competing with more or less the same content,’ agrees Jakob Svensson, C-Map product manager. That’s not necessarily a bad thing: many of the surveys undertaken by the Navy using lead lines and bearings were extremely accurate.īut it means that everyone is using the same basic cartography data. The fact that they have been digitised and appear on a gleaming piece of 21st century technology doesn’t change the antiquity of the data. Well, much of the world’s waters are charted according to surveys that go back decades, if not centuries. ‘The benefit is that we’re fully aligned between the design of the charts and the plotter,’ explains Garmin sales manager Nick Meadow. Garmin owns Navionics and Raymarine is rolling out its own Lighthouse charts, named after its award-winning MFD software. ![]() Garmin takes a different approach, blending Navionics cartography and its own proprietary data in the form of its BlueChart product.īut in fact, each MFD manufacturer is keen to steer you to a specific source of data.ī&G is part of a large group of marine brands that includes C-Map, so it is naturally leaning that way. Modern MFDs from Raymarine and B&G are flexible and support the two main sources of charting: Navionics and C-Map. Or you could be planning to navigate on a tablet, dispensing with pricey fixed equipment and giving your charts total mobility. Big changes are underway with 3D depth contours that rival video gaming detail now available with C-Map Reveal ![]()
