Since maritime navigation across the globe requires nautical charts, we need to represent the world in two dimensions. We can use many different projections to flatten the world, and Mercator is the most common in marine navigation.
The purpose of this talk will be to address world representation and map digitalization processes used in modern and technologically advanced companies. Today's map cartography needs to be easily accessible from users across the world on a significant multitude of different devices. Therefore 3d modelling and vertical data resolution technologies shall allow that cartography content can be readily available.

We will explain the differences between vectorial and raster maps and how in Navionics we use them.
We will also illustrate and demonstrate drawing of cartography content through overlapping layers and how, in Navionics, we address safety constraints specific to the Marine domain while also preventing data cluttering. We will expose the complexity of digital map distribution systems in Multiplatform environments (web, mobile, and embedded) and the caching and optimization techniques adopted to improve the user experience.


The participation is free but it is mandatory to register online by 30 November at 1:00 pm. The workshop will be on Zoom platform.

About the Company

Established in 1984, in Viareggio, Navionics®, a Garmin® Ltd. Brand, produces electronic charts for the leisure boating market.
We were born from a revolutionary idea: the world's first electronic chart display, or chartplotter. Now we use location services every day on our mobile devices, and maybe even take them for granted. But, think about it: how pioneering is that? This state of mind is what Navionics® is founded on and our focus for future goals.
We want to expand as the global leader in marine content and location-based services built on innovation derived from our lifestyle appreciation, digital expertise and crowdsourcing. Our cartography is available to boaters for use in GPS chartplotters, and within our app for Apple® and Android™ devices.
Our head office is based in Massarosa, Tuscany,  but Navionics also has offices in the U.S. in Dartmouth, Massachusetts and Hyderabad, India.
