Circle list

The way to create directional alerts in poi:

ExtraPoiEditor (EPE) by Turboccc is a Poi editor that can make directional alerts in Poi, in .gpi format for garmin gps.

Unfortunately, the map function in EPE is no longer functional. But EPE is still possible to use by disconnecting the internet function.

Unfortunately, this makes the road a little more difficult.

There are two methods of getting directional alerts.

*Circle list. (work in every Garmin)

*Bearing list. (work in the newer Garmin)

Since Garmin has not implemented this in the GPX schema, only in the .gpi format, Turbo created its own GPX schema for EPE.

Use only CircleList or BeraringList, not both in same Poi if you want to make the alert directional.

The gpi file must be produced with EPE.

EPE can only create .gpi with 1 wave file.

Poi with circleList and bearingList in gpx xml from EPE can look like this:


<wpt lat="59.220829959958" lon="5.1924900244921">

Turboccc created bearingList and CircleList as text in the gpx form so that the gpx file would also work in PoiLoader.

PoiLoader will ignore the Circles and bearing xml.




*Circle list are alert circles inside the proximity.

*Circles that overlap other circles merge into one alert zone.

*When using circle list, the whole alert moves in to the circles.

* No alert inside the rest of the proximity, except inside the circles.

*Crossing the coordinate of the poi before circles gives no alert.

*Crossing circles before coordinates of the poi gives alert.

*The circles must overlap each other for the warning to be continuous.


Driving from A to B gives alert. Driving from B to A gives no alert.



Example: Speed trap, directional with circles.

Type: Along Road.

Distance from Poi to first circle have to be at least 2,5-3 sec, this is the ca. time the nuvi use to turn of alert.

Alert direction: North.

You can use MapSource or Basecamp to find the coordinate and radius of the circles.

Example: Section camera, 3km section

Type: Along Road

Alert direction : North

Example of directional POIs.

*The first:(Speed 50 East) by driving over the poi from East to West ,the circles alert will turn off.

*Second:(Speed 50 North East) Narrow alert zone.
