See www. Hoolie Well-known member. Yes, i am not living in UK area and plan to go a bit further. So looking for working vector charts for my plan. AntarcticPilot Well-known member. Agree with those who say it isn't worth the bother. Easy enough to get them from various Torrents it's a pretty big download , but a they are vastly out of date and b the level of detail is inadequate in confined waters.
Fuirther points are that although widely available, they are in breach of copyright and that getting a safe download without the potential for getting viruses is a matter of pot-luck. I have a copy, but frankly would only ever regard them as a planning tool at most. Oldhairy New member. For legal purchase go to jeppesen marine. AntarcticPilot said:. AndyL Member.

The created files are quite large, but is in a format optimized for quick loading. OpenCPN is trading, creation time and size, for fast rendering when actually using the vector chart.
To avoid getting a very long series of SENC charts being built at the same time, use single chart mode, for better control. This is certainly called for in areas that are densely populated with vector charts. Single chart mode and quilting are explained on this page Chart Quilting. The new and easy way to do all this in OpenCPN version 4.
The button is found at the bottom left of the dialog. The process will take quite some time, depending on the computer and number of charts, the first time. Adding a few charts or updating existing charts should be quick once the initial processing is done.
As a user you only have to make sure that the update files are saved in the same place as the base-chart. Don't forget to remove the updates to the old edition of the chart.
In case of missing revisions in a series of updates errors may be introduced. OpenCPN will pop up a warning dialog with this content:. CMversion2 Charts are different from the S57 vector charts, and has it's own data structure consisting of a number of folders and files. This is the version, or edition, of the CM93 -v2 release. There is also support for multiple, as well as multiple partial, CM93 datasets.
The first four numbers describes the latitude and the last four, the longitude of the SW corner of the area covered. This is a typical content of the CM93 V2 top directory. Each of these sub-directories in turn contains directories with the individual charts.
Where Z contains overview charts and G contains harbor plans. Note that, generally, not all of these are present in each subdirectory. The individual chart tiles in these directories have the same logic in the naming scheme as described above.
A few hints. The smallest scale charts in CM93, the Z scale and A scale charts, will not be outlined. Neither will all available charts be visible as outlines at the same time. The reason for this is computing speed and clarity. Generally the next level or two of larger scale charts are shown.
When large scale plans are available directly from A scale charts, with no intermediate charts, the outline of the larger scale charts will be visible from a zoom level between 1. Generally in areas where only A or Z scale charts are available, expect potentially dangerous omissions.
Warning, do not use CM93 small scale charts alone for navigation without referring to other sources. A typical example is Swedish chart names. Trace Chart Files Tab. Share via Share via Chart Files Tab The potential danger to the mariner increases with digital charts because by zooming in, he can increase the chart scale beyond what can be supported by the source data.
