Cartography overview
Raster Navigational Chart (RNC) — A Raster chart is a digital image of a paper chart, and therefore the available information is limited to the information available on the equivalent paper chart.
Electronic Navigational Chart (ENC) — ENCs are Vector based charts and include information that is not available on paper or Raster charts. Objects and features on Vector charts can be selected to obtain information that otherwise would not be readily available. Chart objects and features can also be enabled and disabled, or customized.
The level of detail and features available on charts vary depending on vendor, chart type, subscription level and geographic region. Prior to purchasing charts, check the vendor’s website to establish what level of detail is available on the charts you want to purchase.
The information relating to available chart detail and settings in this manual should be treated as guidance only, as it is subject to change, which is not under Raymarine’s control.
The Chart app range scale will affect the level of detail shown onscreen. Generally, more detail is available at lower ranges. The chart scale in use is indicated by the scale indicator, the value displayed is the distance that the range scale line represents onscreen.
You can remove and insert chart cards at any time. The MFD will automatically detect compatible chart cards and you will be asked if you want to change your current selection.
For chart card selection details, refer to: Cartography settings menu
Different cartography types can be viewed simultaneously using an app page that includes multiple instances of the Chart app.
