I need feed back if this is working on 98,2000,Vista and 7.

OK on Windows 7 (just need to paste the text in "Search programs and files" as there is no Run button)

My opencpn.ini GRIB values are as follows: (are they correct?)

ShowGRIBIcon=1
GRIBUseHiDef=1
GRIBDialogSizeX=1292
GRIBDialogSizeY=786
GRIBDialogPosX=-71
GRIBDialogPosY=159

sinbad,

openCPN openCPN just saves the dialog properties when it is closed, to display it equally next time. So values are fine, as long as the dialog is fully visible in your screen.

Agreed, win is messy here; about every major OS release has moved this folder, and the environment variable has changed as well. The APPDATA is set since W2K, prior to this I think it was a fixed dir off USERPROFILE (I believe in W98, ME, and NT flavors). Also on W98 the location varies depending on whether individual user logins are set up or not.

We need to get all this into the wiki, as it is a very common question. More input from windows users is welcome.

A good idea.

Due to other changing UI (the Run... item is optional and renamed depending on OS), it might be best to just mention the folder, current environment variable, and a few ways to get to it (e.g. Run..., using Explorer directly, "explorer %appdata%" from a command prompt)

Hello we are thinking of getting a Bluetooth GPS receiver and trying to interface that with open CPN. Will OpenCPN recognize a Bluetooth device? Whenever I select an NMEA source openCPN lists COM3, COM4, AIS port and GPSD. What do these mean? If we can't use a Bluetooth receiver could we use a USB GPS?

Any GPS device that emulates a serial port will work. That should be the case of either a Bluetooth or USB GPS.

COM3 and COM4 are physical or virtual ports already present on your machine
AIS means that you would be using an AIS receiver (for which the COM port number is defined is the AIS tool pane) for your navigation data
GPSD is a networked GPS system. You don't need to worry about it.

Cool thanks.

Hi all,
I am not sure if it is the right thread for posting, but anyways ...

I was worried by the lack of details using opencpn and the cm93 2009 charts. And I saw the same place with the same charts rendered by Maxsea. There were a lot more of details. Investigating further, we found that the older CM92 v2 charts had all the missing details rendered by opencpn (albeit odd rendering of rocks limits by silly question marks). Here are the screenshots of the area ( but it is not specific to that one) Does anyone have an idea of where the problem comes from ? (attached a screenshot of the opencpn config too)

I think what you're referring to is in my bug report (screenshots here) concerning drying areas.

The area is green (falls dry at low tide) and normally (as in your maxsea screenshot) negative (underlined) depth level figures are indicated so as to permit prediction of water depth at a certain tidal level.

The difference between 2002 and 2009 is minimal, although there are some depth contours across the drying area. Note the 2009 CMAP charts are also v2, the later ones don't work in opencpn.

Zoef, note that the data is contained in the CMAP data set - it's displayed in maxsea!

I stand corrected. However, does this mean that the problem Ptizef described in beta test/technical post 271 was also due to rendering problems and not to missing files?

I remember the issue Klaas, was a comparison of various programmes performed? I think it affected certain smallish areas only.

Ptizef discovered that at a certain location, of interest to him, the level of detail had gone down. I don't know if this is an isolated case or more widespread.
To check if it was an Opencpn issue or a c-map issue I ran both the 2003 and the 2009 version on the almost antique CMAPECS software. Again, the 2009 version had (for the particular location) less detail.
Ptizef solved his problem by porting detailed 2003 maps into 2009.
Did anybody compare the 2 c-map versions using Maxsea?

Well, I did, there is no visual difference in Maxsea for the two versions of CM93. There have always been less sounding in the grrenish area of CM93 than in the bsb charts but it is not the point. the problem lies in the boundig lines (is that the right name ?) which dont show in opencpn, despite the fact that they exist. They are not rendered anymore, as if they changed of type between the two versions of cm93 ...

Frank, if you check out my screenshots, there arent ANY soundings in the greenish areas in opencpn..
