TIMEZERO Update for MegaWide Charts (Vector and Raster)

Update for MegaWide Charts (Vector and Raster)

• Data Type : UPDATE FOR VECTOR OR RASTER 
• Chart Size : MegaWide
• Manufacturer : C-MAP (Vector Charts) OR MAPMEDIA (Raster Charts)

Update for your MegaWide Charts for both Vector and Raster type charts, created by TimeZero. It lets you stay up to date with the latest navigation data and features without needing to repurchase a whole new chart.

IMPORTANT

• You must previously have a MegaWide Raster or Vector Chart in order to apply this update.

FEATURES 

Altimetry

TIMEZERO and Furuno NavNet(3D & TZT) use MapMedia.mm3d altimetry to portray the shoreline correctly. There are several benefits, such as fast identification of port entry or identification of certain shoreline characteristics. Altimetry also enables you to maneuver in a realistic perspective view with respect to the horizon.

Satellite Photographs

TIMEZERO and Furuno NavNet(3D & TZT) use satellite photos in an innovative and entertaining technique known as PhotoFusion. This innovative technology combines satellite photographs with raster or vector charts to deliver only the information required for safe navigation in a simple, realistic manner. Included with each .mm3d data pack is a standard resolution satellite photographs. Only select areas have high definition satellite photos. MapMedia continues to collaborate with data providers to expand and update the collection of satellite photographs.

Bathymetry

MapMedia .mm3d bathymetry is based on the visual interpretation of chart contour lines. This 3D model is highly useful while entering a port or harbor, offering another navigation tool to keep you aware of underwater threats.

The S-52 Vector Chart Standard

The International Hydrographic Office (IHO) produces the S52 standard. S-52 is an internationally accepted standard that governs electronic vector chart presentation and iconography to make it easier to read and comprehend. MapMedia.mm3d vector charts meet this worldwide standard.

VECTOR CHARTS VS RASTER CHARTS

(Vector: left side / Raster: right side)

Raster Charts:

Raster Charts are an identical representation of the traditional nautical paper charts, since they are digital scans of printed lithographic charts. This is ideal for users that have always used nautical paper charts because they are able to find the exact same information on screen. 

Pros:

• Looks like a paper chart.
• Font size gets bigger when zooming in.
• More information regarding the shore like churches, beaches, streets, etc.
• The scale is clearly defined making it easier to judge distance by eye.
• Information about buoys and lighthouses are placed directly next to the objects.

Cons

• Zooming works in steps meaning a chart is enlarged until it jumps into the next scale.
• Specific information cannot be switched on or off.
• a computer is not able to interpret the picture so there are no alarm functions available.

Vector Charts: 

Vector Charts are a rendering of a lithographic chart in a point-by-point format. Vector charts are composed of mathematically defined geometric shapes: lines, objects, and fills. The data is stored in a database and drawn on the computer or plotter screen by the software, making the display different from Raster Charts. 

Pros:

• Easier to upload due to a smaller file size. 
• It offers a modern a clean presentation.
• Gives you the possibility to switch on and off many layers to obtain only relevant information.
• It has a continuous (less step) zooming.
• You can switch on alarm functions.

Cons:

• When switching off a layer, you might miss relevant information.
• The font size is always the same size making it a bit more problematic for smaller screens.
• You can easily loose the overview scale since all zoom levels look similar. 
• Scarce land information.
• If you need specific information about buoys or lighthouses you need to use a specific window.
