Would it be possible to log water depth at various positions via a depth sounder ?

You can send to OkMap your position (and elevation) using the OkMap proprietary protocol.
Specifications are here: http://www.okmap.org/forum/topic.asp?TOPIC_ID=555

hi,

to log water- depth. It would be neat to also be able to log depth or a marker on the Ok live map from my vb.net application running in parallel . Possible ?

Yes the two things are indipendent.
Remember that a sarial port cannot be shared, so the two programs should run using different ports.
What is the purpose?

hi,

Would it be possible to run okmap on one port and simultaneously run a vb.net application in background which receives and logs to a file nmea depth sentences on another serial port ?

hi,

I have sent you an email with relevant information.

OkMap should receive data via two serial communication ports.
One port (already managed) receives NMEA sentences from a GPS device.
The second port (to be implemented) should receive depth data.
The first port receives data every 2-3 seconds.
I don't know the frequency of depth data. OkMap can associate the last position data received from GPS and the last depth data received from second serial port.
I know that there are NMEA standard for depth data also.
The only problem is to have all hardware necessary for implementation and tests. If some depth sounder manifacturer is interested in this.... Do you know someones?

Actually the sentence can be in any format that OkMap prefers since input is simulated (sent via rf from a real device to pc port). Can this depth data be logged to match with Okmap's position ?

Actually OkMap is able to understand only a subset of NMEA sentences using one serial connection.
These sentences are the most used in GPS communication.
A dept sounder, connected via a serial port, uses other sentences.
Does the dept sounder return the geografic position also? (otherwise OkMap should use two serial connections).
Where is possible to find the thecnical specifications of serial connection and the NMEA sentences format?
In every case it would be difficult for me to test this.
