Integration and Automation
Henry is from the same team that produce TotalTide, which remains the world's most powerful tidal prediction application of its kind. TotalTide can be easily and fully integrated into Henry. Ports and streams can be displayed as overlays on all types of chart and their property sheets can be displayed from the chart context menu.
Predictions for tidal heights and rates (tidal diamonds) are calculated from UK Admiralty data. To do this the system needs to be able to calculate the relationship of the earth, the sun and the moon. This also gives us the capability to display such things as sunrise times and moon phases for anywhere on the planet. Tidal heights are displayed as graphs and tables. Tidal rates are also tabulated but can also be displayed on the chart as annotated vector arrows.
You can write your own applications to use Henry's functionality to open existing or create new overlay and route documents, then read and modify information for individual overlay points, waypoints and route legs from these documents. A useful application for this can be importing routes into Henry from other sources (database, Excel spreadsheet etc). More details about Henry's COM interface can be found here.
If you need Henry's chart capabilities within your own applications, then you should take a look at our chart display and navigation SDK - ENCXTM.
Henry can accept a wide range of data via the industry standard NMEA protocol. The interface learns about the data available on the NMEA port and configures itself appropriately. The NMEA channel is used to read position information, such as from a GPS, heading information from the ship's gyro, and ARPA information from the radar. Alarms can be associated with all the channels and the ship can be configured to use position estimation if the navigation channel drops out.
