Henry runs on Microsoft Windows XP or later (including Windows 8.1).


  • Displays information over lots of different chart types at the same time
  • Overlay georeferenced aerial or satellite imagery on charts
  • Stores, assesses and brings together hundreds of pieces of raw data quickly and easily
  • Simplifies digital chart management and displays ARCS charts undistorted
  • Displays almost all types of charts and supports a wide range of chart formats
  • Integrated Tides Database and Pay As You Sail functionality
  • Simultaneous viewing of the same file set by multiple users
  • Zoom and pan the display at the same time

Example applications

  • Route planning for large vessels and containers in the oil industry
  • Fleet vessel monitoring for off-shore industries, such as work boats servicing wind farms
  • The verification of new chart data by hydrographic offices

As a GIS system with a marine focus

The accurate geodesy and attention to detail in Henry makes it popular with hydrographic offices for verifying new chart data. Henry is one of the only chart tools to display ARCS charts undistorted, using the original projection and including the original marginalia.

Henry has comprehensive support for chart data formats, datums and grids. It supports a variety of sources of geospatial data, and can overlay georeferenced aerial or satellite imagery on charts.

Henry can display AIS and ARPA data from NMEA files, and geospatial data stored in spreadsheets. For more complex needs, Henry has an SDK that allows the import and export of data to be automated.

Supporting digital chart production

Supported chart formats

ENC, S63, ARCS, AML, NTF, HCRF, Shapefiles, BSB, ASRP, CRP, GRP, CADRG, CIB, GeoTIFF, VPF (DNC, VMap, UVMap), manually georeferenced images such as aerial photographs. 

Henry is a powerful tool for quality assurance of digital charts.

Henry can display S-57 ENCs in strict accordance with the ECDIS performance standards, allowing digital cartographers to test and verify their ENCs during production. Aerial photographs, satellite imagery, and other sources of data can be overlaid onto ENCs, making quality assurance less onerous and more rigorous.
