[navigation/osm] Error in the computed distance

Reported by: pini Owned by: cp15
Priority: major Milestone: version 0.5.2
Component: mapdrivers/OSM Version: git master
Severity: Keywords: notification, directions, distance

Description

Hi,

With vehicle_demo + the position and destination below (to use with an osm map including France), the computed distance suddenly drops to 800m when arriving around 1100m:

mg:0x80cfb 0x587eb5 type=bookmark label="Position" path="Position"
mg:0x80c6a 0x58796c type=bookmark label="Destination" path="Destination"

Thanks.

This bug is still valid. Steps to reproduce:

1- use OSM map for France

2- append these lines to ~/.navit/bookmark.txt:

mg:0x80cfb 0x587eb5 type=bookmark label="Position" path="Point 1"
mg:0x80c6a 0x58796c type=bookmark label="Destination" path="Point 2"

3- Configure Navit with the Demo vehicle profile

4- Start navigation using "Point 1" (from bookmarks) as position and "Point 2" as destination. The initial computed distance to destination is about 1650m.

5- When the remaining distance reaches 700m, it suddenly drops to 80m.

6- Try the inverse navigation, from "Point 2" to "Point 1". Initial computed distance to destination is then 1025m. No sudden distance drop during the travel.
