When a query falls between points- averaging?

[lumin8]

When a query falls between two/more points, which point does your code select? What/how might you suggest to grab one/more points and average?

Amending the above question, I can see now it defaults to the next (ceiling) row / column, or can be amended to select either.

I'm looking in to grabbing three coordinates that define a plane bounding the point and projecting the elevation. If you have any advise on adding that functionality in, please holler! If I can figure an elegant way to do this I'll consider a PR. Thanks ~

In a fork dave@9b9ad5e they have added that functionality, but I don't know if it will be correct or more tests need to be done
