2025 Editor's Rating

OpenSeaMap is a global open-source initiative aimed at creating free nautical charts. Established in 2009, the project has recently garnered significant attention for its expansion of nautical information available at no cost. The platform not only includes navigational aids such as lights and various maritime data but also incorporates additional layers of information, including weather updates and details about harbors. Serving as an enhancement to OpenStreetMap, OpenSeaMap addresses the information gaps pertinent to maritime activities, leveraging the same database as its parent project.

Features:

  • Comprehensive free worldwide nautical chart, including high-definition graphics
  • Global geolocation search functionality
  • Chart plotting with continuous tracking capabilities
  • User-friendly creation, editing, deletion, and exporting of waypoints
  • Ability to mark specific locations directly on the chart
  • Zoom features to customize chart viewing according to user preference
  • Direct input of coordinates for display on the chart
  • Offline caching support for up to 1 million map tiles
  • Option to clean up chart cache data at any time

News:

The OpenSeaMap app has introduced a new in-app product called "PRO," which unlocks advanced professional features upon purchase. This initiative aims to foster continued development and support of the OpenSeaMap app.

Disclaimer:

As a component of OpenStreetMap, OpenSeaMap utilizes the same underlying database. Experienced navigators are advised against relying solely on one source of information for decision-making. It is essential to use OpenSeaMap in conjunction with official nautical charts and in compliance with national and international regulations. Notably, this product does not provide depth information.

Important:

Users should be aware that prolonged GPS use may lead to significant battery depletion.
