Subject [jira] Commented: (LUCENE-1781) Large distances in Spatial go beyond Prime MEridian
Date Sat, 08 Aug 2009 00:46:15 GMT

Bill Bell commented on LUCENE-1781:
-----------------------------------

Everything is working except when you use a large area like 10000 miles. I get no results
at this distance when crossing the anti-meridian (180 degrees).

Most of the time this is fine, but specifically when -181 becomes 178 there appears to be
an issue somewhere else in the code and nothing is returned. I believe this code is good,
the issue is somewhere else. Maybe lower left is no longer lower left, and upper right is
no longer upper right? The box is probably too big for the other algorithms. Not sure what
else to check. How it is being used? Regardless this section appears right.

Start here: ctr 39.3209801,-111.0937311
Distance: 7200

I do get results from Hawaii crossing this at 10,000 miles.
