Vector chart formats

Two basic types of vector charts - Livechart, S57 data (Primar & UK HO)

Livecharts - are quality vectored charts that faithfully reproduce the color, accuracy and detail of standard hydrographic office paper charts in a vectored and layered format offering total flexibility not possible with paper charts. Seamless chart selection and the ability to automatically select detail relevant to zoom level or as defined by the user.

A complete Livechart catalogue is also available within seaPro and on the seaPro demo dowload.

S57 - is digital data produced by hydrographic offices and other official sources of chart data. This chart format will eventually replace paper charts. Although availability world wide is limited, coverage is rapidly improving especially in Northern Europe and the USA. S57 charts are supplied either in an encoded format (copy protected) or in a non-encoded form.

Euronav is a distributor for both Primar and the UKHO S57 data.

Raster chart formats

Raster charts are simply made by scanning a paper chart (or in the case of ARCS the original photo masters) and then geo-referenced. The advantage of raster charts is that they are an exact replica of the original paper chart, with no change of data being left off. The downside is that they are just an image, and cannot give the facilities a vector chart can give.

They are relatively low cost to produce, and coverage is consequently very good.

HCRF format:

ARCS - are official raster charts produced by the British Admiralty which offer world-wide coverage. An ARCS catalogue is provided within seaPro and on the seaPro demo CD.

The charts can either be purchased outright (skipper service) or leased with an update service for a year (Navigator service)).

Seafarer - are official raster charts produced by the Australian Hydrographic Office which cover Australasian waters.

NZ Mariner - New Zealand Hydrographic Office Charts.

BSB - Available from a number of manufacturers throughout the world, the prime supplier is Maptech (especially in the USA) including the new BSB 4 version

Note: There are a number of BSB 'dialects', most are supported but compliance with non-Maptech BSB cannot be guaranteed.

Euronav is a distributor for the above products

Maptech PCX - some older chart formats such as PCX are supported, but not recommended due to the age of the data.


	There are two main types of raster chart formats (there are others but they are of little significance) HCRF or more commonly known as ARCS - developed by the UKHO and BSB developed by NOAA. Both formats are used by a number of different suppliers
