Points contained in envelopes that cross date-line - java

Question

I'm using the ESRI Geometry Java API https://github.com/Esri/geometry-api-java I want to construct an envelope and see if it contains certain points. It's possible the envelope crosses the International date line. Here is some sample code I've tried: double lon = Double.parseDouble("179.99"); double lat = Double.parseDouble("0"); Point pt = new Point(lon, lat); double minlon = Double.parseDouble("170"); double minlat = Double.parseDouble("-20"); double maxlon = Double.parseDouble("-170"); double maxlat = Double.parseDouble("20"); Envelope ev = new Envelope(minlon, minlat, maxlon, maxlat); SpatialReference sr = SpatialReference.create(4326); // decimal degrees boolean test = GeometryEngine.contains(ev, pt, sr); System.out.println(GeometryEngine.geometryToJson(sr, ev)); assertTrue("envelope containts point true", test); The test fails, and if I check the print statement I get a json that has swapped my x-coordinates {"xmin":-170,"ymin":-20,"xmax":170,"ymax":20,"spatialReference":{"wkid":4326}} Is there a different/better way to do this?

Here is the solution I found: don't use the ESRI library, use Spatial4j instead. Example use: Add to your pom: com.spatial4jspatial4j0.4.1 in your class: Rectangle envelope = SpatialContext.GEO.makeRectangle(minlon, maxlon, minlat, maxlat); Point pt = SpatialContext.GEO.makePoint(lon, lat); boolean contains = false; if (envelope.relate(pt) == SpatialRelation.CONTAINS) { contains = true; } you can also check if your envelope crosses the dateline with this boolean response: envelope .getCrossesDateLine();
