OpenSeaMap vs V2X2MAP

OpenSeaMap is a worldwide Opensource-project for creating a free nautical chart. Founded in 2009 the project gained a lot of attention lately adding more and more nautical information for free. Not even lights and other nautical infos are provided, but also more and more info layers like weather data, information about harbours and so on. As an add on to the OpenStreetMap this provides all missing info for nautical activities. OpenSeaMap is part of OpenStreetMap and uses the same database. FEATURES: - Free worldwide sea chart (incl. HD chart graphics) - Search for geolocations worldwide - Chartplotting with continuous tracking - Waypoints can easily be created, edited, deleted & exported - Mark locations in the chart - Zoom chart optically to fit your preferred reading size - Enter coordinates directly to be displayed in the chart - Offline caching of up to 1 million map tiles - Cleanup of chart cache data at any time To ensure future development and support of the OpenSeaMap app we encourage you to buy the In-App-Product "PRO". This will help keeping new updates and features coming. DISCLAIMER: OpenSeaMap is part of the OpenStreetMap and uses the same database. As an experienced navigator you should NEVER rely your descisions on one source of information alone. Please keep in mind that the OpenSeaMap can not replace official sea charts on bord of your boat. Please use the OpenSeaMap app only in conjunction with official sea charts and conforming to national and international regulations. Please recognize that no depth information is provided by this product. IMPORTANT: The continued use of the GPS can significantly decrease the battery level.

V2X2MAP makes invisible traffic radio visible: the app shows the C-ITS/ITS-G5 messages that traffic lights, vehicles and roadwork warning trailers around you broadcast on 5.9 GHz – live on the map, on the Lock Screen and in CarPlay. IMPORTANT – RECEIVER REQUIRED: An iPhone cannot receive this radio by itself. Check https://v2x2map.com/ how to get a receiver. The app needs an ESP32-C5 microcontroller as receiver, flashed once with our free open-source firmware. Without the receiver the map stays empty – to try it out, start the demo drive. WHERE IT WORKS: the app receives the European standard ETSI ITS-G5 (5.9 GHz) as broadcast by traffic lights and vehicles mainly in Europe. Other V2X systems such as C-V2X (e.g. China) or ITS Connect (Japan) cannot be received. The demo drive works everywhere. HOW TO SET UP THE RECEIVER (once, about 2 minutes) 1. Connect the ESP32-C5 to a computer with a USB cable. 2. Open v2x2map.com/flash in Chrome or Edge and click “Connect & Flash” – the firmware is written in about a minute. 3. Unplug the receiver once and plug it back in. From then on it runs from any USB charger, power bank or the USB port in your car. 4. Open V2X2MAP – the setup guides you through every step: the app finds the receiver “ITS-G5-RX” via Bluetooth and connects – no account, no pairing code. After that it connects automatically in the car. FEATURES • Traffic-light assistant: when approaching, the signals of your approach per direction (left / straight / right) with the colour as a word, remaining time and distance – already from about 300 m as a preview • Green-wave speed: the speed at which you arrive on green – never above the speed limit • CarPlay: a large, easy-to-read traffic-light board and an info overview right in the car • Live Activity on the Lock Screen and in the Dynamic Island • Warnings about emergency vehicles heading your way and hazard warnings (e.g. roadworks, end of a traffic jam) as notifications – also in the background • Lane-level intersection maps with your lane and turn arrows on Apple Maps • Country rules for Europe and the UK: red-and-amber, turn signals, left-hand traffic, km/h or mph • List of all stations nearby with details • Record drives and replay them later • Optional: forward received messages to the open project OpenTrafficMap (off by default) The displays are for information only and never replace watching the road and the actual traffic lights – traffic rules and the real signal always apply. Receiving radio services may be regulated in your country – see the note inside the app.
