Australian Chart Index

The Australian Hydrographic Office (AHO) publishes official paper charts and Electronic Navigational Charts (ENC) covering Australian, Australian Antarctic Territory, Papua New Guinea and Solomon Islands waters. The Australian Chart Index facilitates discovery of the latest editions and updates for these charting products.

There are currently two methods of accessing the Australian Chart Index (ACI). There is the Australian Chart Index (ACI) and the Australian Chart Index Application.

Australian Chart Index (ACI)

This index provides paper chart and ENC lists in text-based format. Each list has links for each chart or cell to provide access to detailed information about the current edition. Paper chart lists include thumbnail images and links to applicable Notices to Mariners. ENC lists provide details of the current edition and latest update. 

Also included are AusENC (Australia, Voyager, Coastal and Port) pack lists and pdf downloads for Solomon Islands paper chart and ENC indexes (SLB1001 and SLB 1002), Papua New Guinea paper chart and ENC indexes (PNG 2000 and PNG 2001) and for Australian coverage ocean plotting sheets.

Australian Chart Index Application

This is a web service to facilitate the discovery of AHO published paper charts, ENC and AusENC packs in an easy to use graphical interface that has the option to display our ENC content as background. Detailed information about the current editions for all chart products (through all scales) at a selected location are discoverable by clicking the base map.

A dedicated layer identifying the different categories of Zone Of Confidence (CATZOC) allocated to the hydrographic information contained in the ENCs (based on their accuracy and reliability) is also available.

An online user guide has been linked to the application to facilitate its use.

We encourage users to provide feedback and suggestions for improvements to webmaster@hydro.gov.au.

Paper chart indexes for Australian waters coverage (Aus 5000 and Aus 5001) and the GoogleEarth version of the Australian Chart Index have been discontinued.
