Class WaterbodyAndIslandSizeCheck

  • All Implemented Interfaces:
    java.io.Serializable, Check
    public class WaterbodyAndIslandSizeCheck
extends BaseCheck<java.lang.Long>
    This check identifies waterbodies and islands that are either too small, or too large in size. Minimum surface area values are measured in meters squared; while maximum values are measured in kilometers squared. We use two units of conversion to avoid very small/large values. For example, 10 meters squared is .00001 kilometers, and 2,000,000 kilometers squared is 2,000,000,000 meters squared. An island can either be tagged as place=island, place=islet, place=archipelago, or a MultiPolygon Relation with the type=multipolygon and natural=water tags.

      • WaterbodyAndIslandSizeCheck

        public WaterbodyAndIslandSizeCheck​(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:

        This function will validate if the supplied atlas object is valid for the check.
        Parameters:
        object - the atlas object supplied by the Atlas-Checks framework for evaluation
        Returns:
        true if this object should be checked

        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:
        flag in class BaseCheck<java.lang.Long>
        Parameters:
        object - the atlas object supplied by the Atlas-Checks framework for evaluation

        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:
        getFallbackInstructions in class BaseCheck<java.lang.Long>
        Returns:
        The set of instructions to fall back to if configuration results in none.
