[jira] Created: (LUCENE-1930) Scale moderator not in line with sinusoidal projector

Scale moderator not in line with sinusoidal projector
-----------------------------------------------------

                 Key: LUCENE-1930
                 URL: https://issues.apache.org/jira/browse/LUCENE-1930
             Project: Lucene - Java
          Issue Type: Bug
          Components: contrib/spatial
    Affects Versions: 2.9
            Reporter: Nicolas Helleringer


Current implementation in spatial Lucene does :

public double getTierBoxId (double latitude, double longitude) {
  double[] coords = projector.coords(latitude, longitude);
  double id = getBoxId(coords[0]) + (getBoxId(coords[1]) / tierVerticalPosDivider);
  return id ;
}

private double getBoxId (double coord){
  return Math.floor(coord / (idd / this.tierLength));
}

with
Double idd = new Double(180);
in the CartesianTierPlotter constructor.

But current Sinusoidal Projector set and used in initialisation of CartesianTierPlotter does :

public double[] coords(double latitude, double longitude) {
  double rlat = Math.toRadians(latitude);
  double rlong = Math.toRadians(longitude);
  double nlat = rlong * Math.cos(rlat);
  double r[] = {nlat, rlong};
return r;
}

Thus we moderate with idd = 180 a coord that is in a Radian space.

Things to do :

1°) fix idd to : double idd= PI;
2°) Move idd definition to IProjector interface : The coord space should belong to the projector doing the job. Change the code from CTP to use that new interface.

Here is the full patch with the two ranges for latitude and longitude. 

Tests OK.

Nicolas Helleringer commented on LUCENE-1930:
---------------------------------------------

Further more there should be 2 ranges, one for Latitude and one for Longitude as the space for Latitude is [-PI/2;PI/2] and for Longitude is [-PI;PI] in Radians.

Nicolas,

Is this patch contained in one of your other issues?  If so, I'd like to close this one up to prevent confusion.

As Chris work is being released outside Lucene Apache project (http://www.jteam.nl/news/spatialsolr), should we consider this patch to be re evaluated to commit ?

------------------------------------

Hi Nicolas,

I have every intention to commit my work to Lucene in the next week or so.  If you can wait till then, I will include this patch in my patch.

Thanks
