Resampling Options
Resample Period:
- Minute - intervals defined from 00.000 to 59.999 seconds
- Hourly - intervals defined from 00:00.000 to 59:59.999 minutes
- Daily - intervals defined from 00:00:00.000 to 23:59.59.999 hours
Resample Type:
- Average - mean value within resample period (fixed-window averaging without overlap)
- Minimum/Maximum - most extreme minimum and maximum values within resample period
When resampling is selected:
- The timestamps in the data series correspond to the beginning of each resampling interval. The resample interval always begins and ends at an integer multiple of the resample period, so minutes on the minute, hours on the hour, etc.
- If the date/time range on the search has limits that are within a resampling interval, the date/time endpoints are extended to include the entire resampling interval. For example, when daily resampling is selected from 03:00:00.000 on Monday to 20:00:00.000 on Thursday, the date range is extended to 00:00:00.000 on Monday to 23:59.59.999 on Thursday.
- Note that tides are not filtered out in resampled products. No anti-alias filtering done (this is why only averaging and min/max are offered at this time).
For more complex subsampling, CodeRunner (see CodeRunner Help\) is an alternative resource.
