[ckan-dev] ckan-dev Digest, Vol 97, Issue 10

Tue Nov 20 04:04:43 UTC 2018

Thanks Eric and Andrew.

The code you gave worked Eric
    {% snippet "spatial/snippets/spatial_query.html", default_extent="[[-49.43,160.74], [-32.43,185.91]]" %}

Could the code be modified to cope with this scenario - should I raise an issue?  Meantime maybe the documentation should include this example, noting to add 360 to any -ve longitude values as a workaround.

Cheers
Aaron

Your syntax here looks right, but I suspect that you've got an issue with the +- 180 degree line.

Try this:

    {% snippet "spatial/snippets/spatial_query.html", default_extent="[[-49.43,160.74], [-32.43,185.91]]" %}
