Feature: Locating Nearest node on a Way - pick closest way

    Background:
        Given the profile "testbot"

    Scenario: Nearest - two ways crossing
        Given the node map
            |   | 0 | c | 1 |   |
            | 7 |   | n |   | 2 |
            | a | k | x | m | b |
            | 6 |   | l |   | 3 |
            |   | 5 | d | 4 |   |

        And the ways
            | nodes |
            | axb   |
            | cxd   |

        When I request nearest I should get
            | in | out |
            | 0  | c   |
            | 1  | c   |

            | m  | m   |
            | n  | n   |

    Scenario: Nearest - inside a triangle
        Given the node map
            |   |  |  |   |   | c |   |   |  |  |   |
            |   |  |  |   |   |   |   |   |  |  |   |

            | a |  |  | x |   | u |   | w |  |  | b |

        And the ways
            | nodes |
            | ab    |

            | ca    |

        When I request nearest I should get
            | in | out |
            | 0  | y   |
            | 1  | z   |

            | 3  | u   |
            | 4  | w   |

    Scenario: Nearest - High lat/lon
        Given the node locations
            | node | lat     | lon  |
            | a    | -85     | -180 |
            | b    | -85     | -160 |

            | y    | -84.999 | -160 |
            | z    | -84.999 | -140 |

        And the ways
            | nodes |
            | abc   |

        When I request nearest I should get
