danics...
By "these" you mean which ones? CM93 or MapMedia? If CM93, refer to the opencpn source code. If MapMedia, well, good luck, we don't know anything about their format.

The format of CM93v3 and it's encryption schema is proprietary and unknown to us. You have to talk to Jeppesen about it.

Re: 3d Vector Sea Maps

It should be relatively straightforward to render 3d vector graphics is opengl mode.

Do you know the internal format of these charts? From where can they be obtained?

Re: 3d Vector Sea Maps

It would be great to have the function of displaying maps in 3D

Of objects format S-57 can take the values ​​of XYZ feature vertices
1. Coastline, Land Area Z = 0
2. Depth Conour = - Z = Value of Depth Conour
3. Sounding = - Z = Value of Sounding

From XYZ data can be constructed surface by triangulation networks

Re: 3d Vector Sea Maps

Hi all.

I am quite new in this forum and very interested in opencpn. So hopefully this is the right task to place an additional question regarding other chart formats:
Is anybody busy with implementing a plugin to handle JEPPESEN CMAP MAX/PC charts?
Is there an "official" way from opencpn community to get in contact with companies like Jeppesen to ask for support?

Thank You!

Dirk

Re: 3d Vector Sea Maps

Some time ago (2012) HotRod reported on the (negative) policy of Jeppesen regarding open software:
Seriously, how much would it cost to get CM93/3 into OpenCPN?

You might contact him if you like to speak to Jeppesen directly.

And please report back about the response you get. You can sent me a PM as well.

Hubert

Re: 3d Vector Sea Maps

Hello all!! Cm93 3D map are not specially detailed to where I use to go fishing. I have connected my GPS and Furuno Sounder and have created a DB with lat, long and deep. Is there any way to plot this in 2D or 3D?

How many points are you talking about? Hundreds? Thousands? Tens of thousands?

Re: 3d Vector Sea Maps

For small thousands, you can create a GPX layer from your data. For hundreds of thousand the performance of such solution will be unsatisfactory and there's nothing better right now.
