seaPro is a ‘multi-fuel’ charting system that utilizes both vector and raster chart formats to provide you with the best choice of quality charts wherever you are in the world. Simply select the charts that suits your geographic location and format preference.
Charts supported by Euronav offer quality, detail, accuracy and coverage in standard formats that are regularly updated.
For GIS (Geographical Information System) users, Livechart and S57 vector charts are also available in various formats such as GXF and Mainfo.
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 available within seaPro and on the seaPro demo CD.
Livecharts can be purchased in packs covering an area, with special National packs giving great coverage at a very effective price
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).
