AIS Depth Details
AIS Depth data is displayed around the current vessel position. The depth data is displayed in meters, and is only displayed for depth data that is less than or equal to 50 meters.
Route Depth Details
Route Depth data is displayed as a buffer around the passageplan (if available). The depth data is displayed in meters, and is only displayed for depth data that is less than or equal to 50 meters.
NAVTEX Details
NAVTEX navigational warnings are globally standardized navigational warnings, and each country provides urgently needed information for safe navigation in coastal waters by an automatic reception system. In Japan, the coastal area is divided into five sea areas and the necessary information for each sea area is provided in Japanese and English. The areas are updated hourly on the map.
Company Area Data
Company Area data from before 2022 is now available in the map.
Nautical Charts Details
| Item | Content | Features | Use Case |
|---|---|---|---|
| Day/Night | Standard online nautical charts for displaying approximate depth info | Bathymetric contour info Data updates are less frequent than UTT Certain areas have more detailed info |
When only approximate depth is needed |
| UTT | An online nautical chart specifically for NAR service, which, in addition to depth data, displays additional chart data, and is updated with ENC level data | Provides the most detailed chart data, in addition to depth. The charts may display data which is being updated by the provider, however. | When desiring the most detailed info possible |
| UTT_WOR | A simplified UTT chart, showing only data necessary for actual voyage use | Since only basic depth data is displayed content which is being updated is not displayed | When grounding risk is the primary concern |
| Old Gen | The previous version of the UTT chart | Displays the previous version of the UTT chart | When desiring old chart data |
| Transp | A chart displaying only water depth | No land data is displayed | When needing satellite ground imagery |
Transas terms of use : link
UTT – is a collection based on agreements with Hydrographic agencies. These UTT tiles are built using our cartographic DB Unidata. The primary difference between TX97 and UTT is that the UTT-collection does not contain charts on internal waterways such as channels, rivers, and the like.
UTT tiles & UTT-WOR tiles. This is the same tile collection.
