The Kpler feed type in ArcGIS Velocity connects to Kpler to ingest automatic identification system (AIS) data, providing real-time visibility into global maritime vessel movements.
Examples
フィードの使用例を次に示します:
- A maritime logistics company uses the Kpler feed to monitor real‑time vessel movements, identify expected arrivals, berthing delays, and deviations from scheduled routes.
- A national government agency uses the Kpler feed for vessel tracking congestion monitoring and to assess maritime traffic density and high-risk congestion zones for safety and compliance.
Usage notes
フィードを操作する際には、以下の点に注意してください:
- The feed uses port 9196; you will need to have this port opened in your firewall to use the Kpler feed.
- You can create consumer groups by using your provided consumer group prefix and appending a unique suffix. For example, if your prefix is cityname-group, the new consumer group IDs include cityname-group-example1 or cityname-group-example2.
- Velocity automatically handles the data schema. Adding fields is not supported because the schema is predetermined and based on the data provided by Kpler.
- Velocity automatically handles the Date and time and Track ID parameters for the feed.
- The data provided by Kpler is in the JSON data format, so the Location parameter is handled automatically when identifying key fields.
Parameters
フィードには、次のパラメーターがあります:
| Parameter | Description | Data type |

Consideration and limitation
フィードを使用する際には、以下の点を検討してください:
Each consumer group can have only one active feed. You can create multiple feeds using the same consumer group, but only one of those feeds can be actively ingesting data.
