[gpsd-dev] [AIS] About offset and scaling

[Christian Gagneraud]

Hi Eric, all,

Currently in driver_ais.c an offset is applied for certain message 
fields (IMO 236 and IMO289 met/hydro message), and a scaling is done 
conditionally in gpsd_json.c.
I think it would be better to apply the offset and the scaling in 
gpsd_json.c. Do you have any objection on doing this?
I think it make more sense this way. No scaling means raw data, w/ 
scaling means "engineering" units. As well when comparing gpsd decoding 
again other decoding, it make the task easier as they show the same 
behaviour (raw + scaling/offset applied).

Regards,
Chris
