Thread: Navitel directional alert for Russia

osiris4isis, did you prepare the bearing list by yourself or you got it ready from Navitel's original files?

They are from Navitel dataset (per first post "Source: Navitel May 2015") The bitmaps and voices are also from Navitel, converted (tweak) to work. Disclaimer: So any incorrect/inaccuracy, blame Navitel

Just curious, because for directional alerts I'm using the bearing angle and distance. IMO both ways ("circle list" and "bearing angle-distance") required a tedious work to prepare the data.
If the result is one and the same (I suppose so), is there any "pros and cons" using circles or angle-distance method?

I think I discussed this in one of my other threads. Basically, I would use bearing list if road is not curvy and distant it not long (ie: tunnel, average cam, or far mobile alerts) Bearing list works great for redlight and fixed cam. Circle list takes more work because the more circles you use the more accurate and multiple notification works. Trying to automate the creation of them is more an art than science (lots of tweaking) Navitel is one of few vendor providing alerts with bearing angles so it's just parsing the alert file and creating the .xml to be created by Garmin Creator Toolkit. I wish Navitel release maps and alerts for U.S.
