AusChartviewerAusChartviewer is a low cost, easy to use application that displays nautical charts in the following international formats:

  • IHO S-63 Protected ENC (including AusENC)
  • S-57 data in unencrypted form
  • Hydrographic Chart Raster Format (HCRF)
  • AusGeoTIFF

It is a desktop planning and reference tool for those who wish to view nautical charts for shore based applications.


AusChartviewer was developed as a shore-based planning and reference tool to provide access to electronic charts for non-navigational purposes. It has powerful data format comparison tools and is useful for marine research, search and rescue, marine accident investigation and Government departmental operational planning. Whilst AusChartviewer includes traditional navigation functions like bearing and distance measurement and a route planning module it will not interface to GPS to display the computer's current position on the surface of a chart.

Because AusChartviewer cannot be interfaced with GPS and Autopliot, it is not suitable for navigation. It is not suitable for commercial vessels required to meet chart carriage requirements under SOLAS Chapter V or National Standards for Commercial Vessels (NSCV) regulations.


The main benefits of AusChartviewer are:

• Fast data loading.
• Seamless display of chart data.
• Ability to display four independent viewing windows that can view and compare any combination of chart data (for example, AusENC, AVCS and AusGeoTIFF).
