When image tile requests crossing a dateline happen, there is a multipolygon that gets passed to the find images function. We don't necessarily want just the tiles that are within those geometries, but also the ones that could be between them.

Thinking about this a bit more, this might expand the domain a little bit too much depending on the bounds of the polygons and turn two halves of an oval shape into a rectangle unnecessarily. I'll try and look into whether buffering the multipolygon is more appropriate here because I am now wondering if this has to do with the inexact boundary of Orthographic (or any curved boundaries). |
