Feature: Projection to nearest point on road
Waypoints should be projected perpendicular onto the closest road, also at high latitudes.
Background:
The coordinas below was calculated using http://www.movable-type.co.uk/scripts/latlong.html
The nodes are placed as follows, with ab, bc and bd all being 1 km in length each:
| | | c |
| | b | | (this is sketch only, real data is in the table below)
| a | | d |
Given the profile "testbot"
Given the node locations
| node | lat | lon |
| a | 80.00000 | 0.00000 |
| b | 80.00639 | 0.03667 |
| c | 80.01278 | 0.07333 |
| d | 80.00000 | 0.07333 |
And the ways
| nodes |
| abc |
Scenario: Projection onto way at high latitudes, 1km distance
When I route I should get
| from | to | route | compass | bearing | distance |
| b | a | abc | SW | 225 | 1000m +-3 |
| b | c | abc | NE | 45 | 1000m +-3 |
| a | d | abc | NE | 45 | 1000m +-3 |
| d | a | abc | SW | 225 | 1000m +-3 |
| c | d | abc | SW | 225 | 1000m +-3 |
| d | c | abc | NE | 45 | 1000m +-3 |
Scenario: Projection onto way at high latitudes, no distance
When I route I should get
| from | to | route | distance |
| d | b | abc | 0m |
| b | d | abc | 0m |
