Data Views

The openEO API supports to look at datasets from different views. Views describe at which resolution and for which spatial and temporal extent the original Earth observation data are processed and hence can be used to run processes interactively on small parts of the original data without need to wait for long-running processes. The idea is similar to what Google Earth Engine does by reducing computations only to pixels that are actually displayed.

Note: This feature is currently not described in the API specification. It will be added after delivering the proof-of-concept.

Example

The following JSON object describes a coarse resolution (0.25° x 0.25°) view of monthly aggregated data.

"view": {
  "space": {
    "srs": "EPSG:4326",
    "window": {
      "left": -10.21,
      "top": 53.23,
      "right": 12.542,
      "bottom": 12.32
    },
    "cell_size": 0.25,
    "resampling": "nearest"
  },
  "time": {
    "window": {
      "start": "2017-01-01",
      "end": "2018-01-01"
    },
    "time_step": "P1M",
    "resampling": "nearest"
  }
}
