Example process graphs?

[m-mohr]

Is there a set of example process graphs for demonstration purposes?

Attached to process graph examples, we may write more if needed.

Thank you, @neteler!

Unfortunately, I observed some issues:

1. They don't have a result node.
2. They are wrapped into an object with key process_graph.

Also, it would be great if the processes would follow the specification a bit more closely so that tooling can handle workflows better:
3. get_data should better be load_collection with a parameter called id. Most of the clients assume that loading a collection is done with load_collection and workflows fail if the process is not available.
4. There's no process that saves the data (save_result) so it's not clear what format the data is stored in.

Fixing 1 and 2 by hand, I get the following graphs, which I can load into the Web Editor. Unfortunately, I can't execute them as the endpoints require authentication (seems related to #18).

{
  "get_data_1": {
    "process_id": "get_data",
    "arguments": {
      "data": "utm32n.openeo.raster.Sigma0_VH_db_20180111"
    }
  },
  "scale_1": {
    "process_id": "scale_minmax",
    "arguments": {
      "data": {
        "from_node": "get_data_1"
      },
      "max": 255,
      "min": 1
    },
    "result": true
  }
}

{
  "get_data_1": {
    "process_id": "get_data",
    "arguments": {
      "data": "utm32n.openeo.raster.Sigma0_VH_db_20180111"
    }
  },
  "scale_1": {
    "process_id": "scale_minmax",
    "arguments": {
      "data": {
        "from_node": "get_data_1"
      },
      "max": 255,
      "min": 1
    },
    "result": true
  }
}

I see that the processes load_collection and save_result are now available. Any example using those processes available?

TODO: There are outdated example process graphs in https://open-eo.github.io/openeo-grassgis-driver/ which need to be updated.
