Hello, I've turned up little in searching for a package that already has this function. Dspat is close but I don't think it does quite what I want.
I have observation data gathered from a ship transect doing a zig-zag pattern. I have the current location of the ship, the ship's bearing, the angle from the transect to the sighting, and the observed distance to the sighting (and the height of the observer above water). Is there already a package/function in R that will "easily" convert this information to the lat/lon of the observed animal? Thanks for any help or guidance.
