Open CPN getting charts to display

Hello everyone and that you in advance for any help that would be given. I have installed Open CPN and have purchased a chart from SeaZone. The chart has been unzipped and put into a directory and seems to be in .tiff format. The download said that it was in Geotiff format. I have added the directory as per the instructions on the CPN website as follows but the Open CPN program still shows the 2D world map that comes as standard install. What am I doing wrong, any help would be appreciated thanks.

C:\C-Plot\weogeo_j122276\data\Data\HydroView Charts\ArcGIS 9.3\Charts
C:\C-Plot\weogeo_j122276\data\Data\HydroView Charts\ArcGIS 9.3\Charts+
C:\C-Plot\weogeo_j122276\data\Data\HydroView Charts\Other\Charts
C:\C-Plot\weogeo_j122276\data\Data\HydroView Charts\Other\Charts+

Re: Open CPN getting charts to display

This charts will not show up "as is" in OCPN.

Please have look to the manual:
Chart Formats | Official OpenCPN Homepage

You will need to convert GeoTIFF to .kap to be able to use them in OCPN

Re: Open CPN getting charts to display

Thank you bcd for your reply. You have pointed me to the chart conversion section of the OpenCPN website, unfortunately being a newbie to all of this i would probably need a little more hand holding than that, sorry having problems all over. Can you tell me the actual program that does this for me, again sorry for my ignorance just trying to get this sorted.

The proper chart conversion section is here Chart Conversion Manual | Official OpenCPN Homepage

Your charts may be a strait conversion with "imgkap", depending on the exact format of the meta info in the geotiff. I've seen a few variations in this respect. There are more options available in the manual, even the "Weatherfax Plugin" can do conversions. In the end there is no simple magic formula, that covers all situations. You have to read the manual ++.

I suppose that you bought your charts for some other purpose and now want to use them with O? Why else buy a non standard chart format?
What area does your chart(s) cover? There may already be ".kap" alternatives available.

Re: Open CPN getting charts to display

No i did buy them for Open CPN, they were they only ones that I could find being new to all this. I will try that conversion software thanks.

The maps that i was after were for mainly the east coast of Australia, New Caladonia and the Pacific Islands. If there is anything like that available i would probably buy that. Thanks in advance if you could point me in the right direction.

Thanks again.

Re: Open CPN getting charts to display

When I open Imgkap a cmd window opens for 1 second then closes again. tif2bsb keeps saying that the program has stopped working and I need to close the program. Any help would be appreciated. Sorry for the pun but am dead in the water at this stage.

I am running windows 7 Ultimate SP1 32Bit OS with 4 gig ram and plenty of hard drive space.

Help please!!!

Re: Open CPN getting charts to display

Both imgkap and tif2bsb are command-line programs, aka "dos programs".
They must be started from the command-line by entering the path to the programs exe file.

Re: Open CPN getting charts to display

You can as well use the Australian AHS ENCs/S-63 charts under the S-63 plug-in for OCPN.
Licenses from AHS and their resellers. They accept the OCPN S-63 UserPermit.
