Frank Greguska commented on SDAP-110:
-------------------------------------
Just a little more background info. This bug was discovered as part of the SLCP
project and was fixed by tiling the data in such a way that no one tile ever
spanned more than 180 degrees of longitude. I would consider that to be a
workaround not an actual fix for the problem though.
I suppose another 'fix' would be to modify ingestion to fail/error if a tile
ever spans more than 180 degrees longitude and leave it up to the user to
reconfigure the tiling scheme so that this is not the case. This seems less
than ideal though.

> URL: https://issues.apache.org/jira/browse/SDAP-110
> Project: Apache Science Data Analytics Platform
> Issue Type: Improvement
> Reporter: Frank Greguska
> Priority: Major
>
> Nexus needs to intelligently handle tiles that are wider than 180 degrees.
> Currently if a tile is ingested that is wider than 180 degrees the indexed
> shape is interpreted incorrectly resulting in missed searches.
> For example, if you create a Solr document that spans the longitude range:
