Detailed Description

Accumulation over a user given period.

The input data is accumulated over a given time interval (given as filter argument, in seconds). This is for example needed for converting rain gauges measurements read every 10 minutes to hourly precipitation measurements. It takes the following arguments:

PERIOD: the accumulation period in seconds (mandatory);
STRICT: if setting the argument "strict" to "true", nodatas will propagate (ie. a single nodata in the input will force the re-accumulated value to be nodata). By default, all valid values are aggregated and only pure nodata intervals produce a nodata in the output.
PSUM::resample = accumulate

PSUM::accumulate::period = 3600
