could open CPN use log files?

i was reading up on the new GPS units, and read that some can save the bottom scan and you send it to the company and they can make you a map of the area you just sent them.

so can open CPN use these? seems like the Lowrance just wants free surveys....

Re: could open CPN use log files?

Get us a sample and we can have a look if there's anything that can be done... So far we have never seen it, so OpenCPN does nothing in this respect.

I use a very high end industrial side scan sonar unit as part of my work (a very small part). The software we use has this as a feature, secondary to geolocating our scans. It works ok if you're into mowing the lawn, otherwise it's just a bunch of disparate transect data. (Think lines not grids). It works for us because we are trying to achieve 100% coverage of our target area (not just cruising around), and we're getting paid to slowly tool up and down and up and down and up and down and up and down and up and down some more. Did I mention how dull it can be going back and forth and back and forth and back and forth at 1 knot?

It would be a fun feature to have in a software package, but I'm not sure current OpenCPN would be the best fit. Maybe as a standalone bathymetric generator (something like the GE chart generator).

I'm working on a project that would have georeferenced depth data in it, but until I have actual results I'm hesitant to delve into it. Need to temper the failures with a success or two before publicizing :-). If I ever get the #{*+%# thing working I'll open source it.
