Class SignPostCheck

  • All Implemented Interfaces:
    java.io.Serializable, Check
    public class SignPostCheck
extends BaseCheck<java.lang.String>
    This check is used to help identify segments that are missing the proper tagging for sign posts. The basic logic of the check is to first find all Edges that are the start of an on or off ramp. Once Edges are identified and filtered, a flag is thrown if one or both of the following conditions are met.

    1) The starting node for an off ramp is missing the highway=motorway_junction tag
    2) The ramp road is missing the destination tag

    If either of these cases is true and ramp is over a certain length then a flag is created. Optionally, branching Edges of on and off ramps can be checked for destination tags. This is configurable to accommodate varying standards in different countries.

      • SignPostCheck

        public SignPostCheck​(org.openstreetmap.atlas.utilities.configuration.Configuration configuration)
        The default constructor that must be supplied. The Atlas Checks framework will generate the checks with this constructor, supplying a configuration that can be used to adjust any parameters that the check uses during operation.
        Parameters:
        configuration - the JSON configuration for this check

        public boolean validCheckForObject​(org.openstreetmap.atlas.geography.atlas.items.AtlasObject object)
        Validates if the supplied AtlasObject is valid for the check.
        Parameters:
        object - the atlas object supplied by the Atlas-Checks framework for evaluation
        Returns:

        protected java.util.Optional<CheckFlag> flag​(org.openstreetmap.atlas.geography.atlas.items.AtlasObject object)
        This is the actual function that will check to see whether the object needs to be flagged.
        Specified by:

        protected java.util.List<java.lang.String> getFallbackInstructions()
        Description copied from class: BaseCheck
        Method to implement for inheriting checks to return the default set of instruction formats that will be the last resort in BaseCheck.getLocalizedInstruction(int, Object[])
        Overrides:

        Returns:
        The set of instructions to fall back to if configuration results in none.
