Area query subdivided by elevation

by AndyAmphlett » Tue Mar 26, 2019 9:06 am


running this type of query - ... 5db8b5f5db - group by grid square subdivided by elevation, only works when grouping by monad. If I change the grouping to tetrads or hectads it runs, but returns no results. I think I recall correctly that the DDb stores monad altitudes for use in this type of query? I assume it should combine these to calculate values for larger squares?

Hi Andy,

Thanks for highlighting the omission. The query now also works for hectads and tetrads.
