NullPointerException in ShapeDeserializer when deserializing 3D coordinates

1

When deserializing geometries with 3D coordinates using the jackson `ShapeDeserializer` I get a `NullPointerException` (s. stack trace below). This is probably due to lines 47 and 60 in https://github.com/locationtech/spatial4j/blob/master/src/main/java/org/locationtech/spatial4j/io/jackson/ShapeDeserializer.java where...

I'm quite confused about distance calculations. I'm using this website as a reference: https://www.omnicalculator.com/other/latitude-longitude-distance Then I got an implementation of a distance calculation (haversine) from here: https://tutorialspoint.dev/algorithm/geometric-algorithms/program-distance-two-points-earth And I want...

JtsShapeFactory MultipolygonBuilder fails to validate shape

3

It is possible to create invalid shapes through the `JtsShapeFactory.MultipolygonBuilder`. You can reproduce by running the following class: ```java import org.locationtech.spatial4j.context.jts.JtsSpatialContext; import org.locationtech.spatial4j.context.jts.JtsSpatialContextFactory; import org.locationtech.spatial4j.exception.InvalidShapeException; import org.locationtech.spatial4j.shape.jts.JtsShapeFactory; public class Main...
