We just wanted to let you know we have fresh new NOAA charts for both Raster and Vector format. There is also Block charts update only available for TZ Professional v3. Please consult the list to see which charts are involved.
Check out our Facebook page to find examples of the improvements to the charts and find out about big changes in an area near you that you may not have been aware of: Vector | Raster
Raster Charts for the Netherlands have been updated within three chart zones.
These Mapmedia chart zones integrate the new routing system in the southern part of the North Sea. This new organisation was put into place on the first of August, 2013 in accordance with the IMO Sub-committee on the Safety of Navigation proposal NAV/58/3/2.
Mapmedia has applied these changes very quickly to our charts to ensure that customers have the most up-to-date information possible for maximum safety.
Here are the updated chart zones:
Here is an example of this update:
As this is a minor chart update, customers will not need to pay if they already own the major chart edition.
Customers who already own the charts WRMEW25MAP5.1, WRMEW28MAP4.1 or MWRMEW46MAP5.1 will therefore access this update for free.
Wide and MegaWide are terms commonly used by cartographic data providers to describe the size of navigation charts. MapMedia, MaxSea’s subsidiary specialized in digital cartography and Raster data treatment, also employs this terminology to better classify its charts offer in both mm2 (for MaxSea v12 and previous software) and mm3d (for TIMEZERO software) formats.
Wide and MegaWide area size vary according to its geographical coverage and the number of navigation charts included within each area.
Wide areas are approximately 3 times smaller than MegaWide areas at some locations.
Let’s take the Mediterranean Raster charts as an example:
WRMEM32MAP6.1 Mediterranean Sea – West
This Wide area includes all the navigation charts available from Gibraltar to the west coast of Italy.
It takes almost 6 old mm2 charts to make the latest mm3d Wide chart.
The West Mediterranean Sea Wide area contains around 575 charts and maps whereas the MegaWide (covering the whole Mediterranean Sea) contains more than 1700 navigation charts and maps.
The level of detail is the same for both sizes as every area includes:
Detailed maps and all ports available
All navigation charts are updated at least once a year. For Raster charts, MapMedia orders all available charts from each local Hydrographic Service every year in order to scan them and convert them to its unique mm3d format. For Vector charts, MapMedia retrieves the cartographic data from its providers (currently Jeppesen and Navionics) and converts it to mm3d as well.
