Jody, Thanks for your comprehensive response.
I'll do as you suggest and try the operations route to start with. FYI, a seismic navigation file contains positions for the towing vessel, airguns (source) and hydrophones in the towed streamers - this is seismic exploration for oil and gas. Many paramters can be computed from the file - velocity, surface currents, separations between the streamers, feather (the angle the streamers make with the planned track), and so on. All stuff that can (and should be) analyzed spatially. Which brings me to another subject - gridding shapefiles. Grids are much more easy to manipulate than vector files - especially in terms of differencing rasters and that sort of thing. Any plans for rasters in uDig??

Aka is this a straight data exchange or do you need user interaction to pick the points? Not sure what information is in a seismic navigation file. You may want to look in the community section, in my folder (ie Jody) there is an operation that exports the selected features to a shapefile. We will need to review the support export support provided by data wizards, most of the work has focused on importing up till now. > I have successfully downloaded the latest SDK and built the distanceTool - very > straightforward thanks. > Yeah! I think you are one of the first to find it straight forward - which indicates we need to provide more background on eclipse for everyone else ;-) > If I can get this to work I would like to build a more generalized translator > which I'd then submit to the community. > That would be great, as a young open source project we are fairly light on process and fairly big on trust, so when you are ready just ask and we can get you svn access so you can set yourself up in the community folder.
