CartesianPolyFilterBuilder doesn't handle edge case around the 180 meridian
---------------------------------------------------------------------------
Key: LUCENE-2359
URL: https://issues.apache.org/jira/browse/LUCENE-2359
Project: Lucene - Java
Issue Type: Bug
Components: contrib/spatial
Affects Versions: 3.0.1, 3.0, 2.9.2, 2.9.1, 2.9
Reporter: Grant Ingersoll
Assignee: Grant Ingersoll
Priority: Minor
Test case:
Points all around the globe, plus two points at 0, 179.9 and 0,-179.9 (on each
side of the meridian). Then, do a Cartesian Tier filter on a point right near
those two. It will return all the points when it should just return those two.
The flawed logic is in the else clause below:
{code}
if (longX2 != 0.0) {
//We are around the prime meridian
if (longX == 0.0) {
longX = longX2;
longY = 0.0;
shape = getShapeLoop(shape,ctp,latX,longX,latY,longY);
} else {//we are around the 180th longitude
longX = longX2;
longY = -180.0;
shape = getShapeLoop(shape,ctp,latY,longY,latX,longX);
}
{code}
Basically, the Y and X values are transposed. This currently says go from
longY (-180) all the way around to longX which is the lower left longitude of
the box formed. Instead, it should go from the lower left long to -180.
