ADEM Timerange Parameter
Autonomous DEM APIs provide a timerange query parameter. The timerange that you supply is in human readable format:
last_<N>_<minute|hour|day|week|month>.
For example:
last_30_days
last_30_minutes
last_2_weeks
The responses are aggregated over a sample period which is a function of the time interval requested, such that the granularity decreases with increasing interval. This keeps the number of sample returned to a reasonable number whilst still allowing higher resolution at small intervals.
| Interval (days) | Sample Period (minutes) |
|---|---|
| <= 1 | 5 |
| <= 3 | 15 |
| <= 7 | 30 |
| <= 14 | 60 |
| <= 21 | 120 |
| >21 | 180 |
Alternately, you can specify an exact time range using the start and end query parameters. These accept Unix
timestamps. For example:
start=1686814360&end=1686900760
