Vector Charts by Zydro

the Nautical Chart API for web apps & maritime robotics. Add beautiful, informative vector nautical charts to your maritime product. Built by @zydromarine

At @zydromarine we love pushing the limits of maritime geospatial data in the browser.

Pictured: our recent work visualizing charts, bathymetry, subsea perception & more... pushing the boundaries of what you can do with vector tiles

If this seems cool, we're hiring! (below)

New feature: we’re working on deriving buoy pairs, route centerlines, and other semantics, to help deliver navigation recommendations!

Lots of possibilities for great maps on top of the vector charts api:

Coming soon: We're building a style editor into the Vector Charts dashboard, allowing our users to deeply customize the chart styling for their application!

We had a busy 2025 releasing the Vector Charts API, helping leading USV & AUV companies integrate our product, and hanging out on boats.

What's next? More data, better chart-informed path planning, and integration into @zydromarine's larger ecosystem for C2 & autonomy.

New chart data available in Vector Charts: We've just added support for major US inland waterways, with charts provided by the US Army Corps of Engineers.

Along with this new data, we're rolling out improved inland symbology.

We're showing off Vector Charts at Workboat - Stop by Booth 3773 to chat maritime data & see our point-to-point routing APIs, map rendering, and more!

Who builds Vector Charts? @zydromarine!

Zydro builds foundational building blocks for trusted autonomy at sea, from maritime geospatial data to autonomy & mission planning.

More news coming soon from Zydro...

We just dropped a new API for our business customers: the Shoreline API provides a dead-simple method for obtaining a land/water shoreline mask based on ENC data.

Our Point-to-Point Routing API can be used to build powerful user experiences for route planning.

In this example, our demo app shows multiple route alternatives - One for "Shortest distance" and one with wider safety margins - and allows the user to swap between them.

We're rolling out our Point-to-Point Routing API in select to our pilot customers.

Watch how the algorithm routes to avoid shallows & follows fairways.

We're constantly improving our system and checking it against the domain knowledge of expert boaters.

Vector Charts isn’t just for integration into new products. You can also drop it directly into tools you already use!

For example, here’s how you can add our charts as a background layer in #QGroundControl, for use mission planning with #ardupilot USVs:

Next on our list of compatible libraries: MapLibre GL JS. Born as a fork of Mapbox, MapLibre has the same capability to render Vector Tiles with WebGL!

This week, we’re diving into how you can use our API with some common mapping libraries, GIS tools, and drone command & control software.

Follow us to learn how you can add nautical charts to Mapbox GL JS, OpenLayers, QGroundControl, QGIS and more!

Satellite imagery, 3D terrain, AND nautical charts? All possible when you combine modern web mapping libraries with our nautical chart tile API.

[Vector Charts by Zydro @vectorcharts]

We just shipped a HUGE style update improving portrayal of navigational aids & lights, transit lanes, landmarks, and 100s of other layers.

We're building the world's best nautical chart by thoughtfully combining the maps mariners understand with new tools for the modern web.

1 month from now, we'll be at IBEX 2025 - The leading marine industry event for boat builders, electronics manufacturers, innovators & entrepreneurs.

If you have an interest in nautical charts or just want to talk about maritime data, let's meet and chat!

Our vector tiles are supported by many modern map libraries including Mapbox GL JS, MapLibre, and OpenLayers.

For older libraries that only support raster imagery, we also serve raster tiles.

We're publishing examples for many libraries here: https://t.co/nBuegQTo85
