Features that cross the dateline #65

Closed rclark closed 9 years ago

rclark commented 9 years ago

If you calculate the tile-cover for a feature that with X coordinates > 180, you can end up with bogus tile coordinates, for example [260,52,8]. Would it be worth a PR that tries to coerce to coordinates within the right limits (in this example, [4,52,8])? Or is it better to handle this outcome in the downstream app?

I would expect this to be handled on the downstream app, since the wrapping is lossy (e.g. you can end up with coordinates you don't know what to do with).

:+1: to managing this downstream.
