FAQ Some of these questions are frequently asked, the others should be!

The price depends on how many licences and which licence you need. Reductions are available for large quantities. Please contact us with your requirements and we will discuss the pricing.
ENC (Electronic Navigational Chart) is an application of the wider S-57 vector standard. There are other S-57 'products' (e.g. IENC, AML) but ENC is the most common one. This has led to the terms 'S-57' and 'ENC' being used interchangeably. See Vector and Raster for more information. Some organisations have started using the term ENC only if the charts are official data.
S-63 is an encryption standard that is applied to commercial S-57 ENC charts. To decrypt a chart encrypted with S-63 both a chart permit and a user permit is required. See Chart Purchasing and Licensing.
There is a lot of unlicensed ENC data about though much of it is for demonstration purposes and not for navigation. But NOAA publish a lot of ENC data free of charge. See NOAA ENC Data.
For ENC charts, please see this. For raster charts, the projection is the same as the equivalent paper chart.
When overlaying information onto charts drawn by ENCX you need to use the GeoPix class to convert geographical (lat lon) coordinates into pixel coordinates. There are different methods for points, lines and areas (polygons).
Yes. This is quite easily done. If you have customers with access to unlicensed charts for the waters in which they operate (e.g. the US market) you could ship them software without a dongle. The software uses ENCXUDE. Later, if they needed to use licensed charts in other parts of the world they could upgrade by buying a dongle and the software would switch to using ENCX to display the charts.
