Incorrect display of a turn at a roundabout in the widget

[Zirochkabila]

Description

Since for "normal" crossings the widget for the next turn shows where one should turn (sharply / normally / slightly right, etc.), would be expected that the symbol for passing through the roundabout not only correctly says the number of exit out of it (as it already does) but also reflects the path to take. The path should always come into the roundabout scheme from the bottom (this is the case), but also out at the correct angle and exit number. Currently, the exit number is correct but the angle is sometimes not, and quite gross discrepancies may occur, as shown in the video. OSM OsmAnd Map here

Steps to reproduce

• Navigation
• From 33.02288, 35.67579 to 33.02410, 35.67079

Actual result

Expected result

The path should always come into the roundabout scheme from the bottom (this is the case), but also out at the correct angle and exit number.

We have no solution except displaying real turn structure in a side map - calculating angle is really faulty operation. So it's a duplicate

The strange thing is that for countries where cars drive on the left side of the road (so roundabouts are taken counter-clockwise), it looks to work fine.

Just like this:

The behaviour seems quite inconsistent. These two examples show somewhat opposite behaviour.

In the first, the widget shows less than 180 degrees while the route is more than that, the second shows way more angle than the route.

I'm still having the same problem with version 4.5.10 of Osmand+ on Android. The next turn widget symbol, on the same roundabout, behaves very strangely and contrary to logic depending on the exit I choose.

I have the same result with the map rendering engine 1 and 2.

I've already noticed this problem with version 4.4 and I'm convinced that the symbol was correct before.

I hope this will be corrected in future versions as it's quite confusing when driving.

@bobeeeze this issue is considered as Not planned:

• The next turn widget each time displays the correct exit to be used
• OsmAnd do not use preloaded images for this type of widgets, the picture of a roundabout is recreated every time according to map data
• as stated above, calculation of a turn angle is a faulty operation
