Datasets on or near the international dateline (e.g., Fiji) are not handled properly

• datacube-wms version: latest Docker build on 21 May 2019
• Python version: Python3
• Operating System: Linux

Description

No data for Fiji is rendered.

WMS GetFeatureInfo returns a list of dates where data is available, and this is different to the list of data the GetCapabilities returns.

What I Did

• Indexed USGS Landsat 8 Surface Reflectance for Fiji
• Set up OWS on top of it
• Noted that I can't render data for Fiji from OWS in Terria

I believe the problem is that update_ranges.py uses UTC dates - but the bulk of datacube_ows uses local solar time.

Seems to be fixed a bit, and data is rendered. There are some odd issues remaining. For example, when a scene straddles the dateline in Fiji, it wraps around the world the wrong way. See:

The data does render when you zoom in, though:

Note that "seems to be fixed a bit" refers to the antimeridian branch which has not yet been merged into master.

At this stage I am not sure how to handle this remaining issue.

Now merged.
