Queries with mulitple timeframes
Question. Suppose I want to know for an area what the surface is that the PET is above 41 degrees between 12 and 16 o'clock. For this question I made an area and the HEAT overlay containing 5 timeframes corresponding to the 12 and 16 hours.
Then when I ask the question (query):
Select.Landsize.Where.Area.Is. (Id area) .and.Grid.is. (Id grid) .and.mingridvalue.is.41
Do I get the average surface between 12 and 16 o'clock that is above 41 degrees (PET) as an answer? In other words, Tygron calculates the average of the different tiimeframes. Or is the first or perhaps last timeframe used to answer the query?
