Processing Graphs

This section introduces the processing graph API of Geo Engine.

ResultDescriptor

Call /processingGraphs/{processingGraphId}/metadata to get the result descriptor of the processing graph. It describes the result of the processing graph by data type, spatial reference, temporal and spatial extent and some more information that is specific to raster and vector results.

Example response for rasters

{
    "type": "raster",
    "dataType": "U8",
    "spatialReference": "EPSG:4326",
    "measurement": {
        "type": "unitless"
    },
    "time": {
        "start": "2014-01-01T00:00:00.000Z",
        "end": "2014-07-01T00:00:00.000Z"
    },
    "bbox": {
        "upperLeftCoordinate": [-180.0, 90.0],
        "lowerRightCoordinate": [180.0, -90.0]
    }
}

Example response for vectors

{
    "type": "vector",
    "dataType": "MultiPoint",
    "spatialReference": "EPSG:4326",
    "columns": {
        "id": "int",
        "name": "text",
        "value": "float"
    },
    "time": {
        "start": "2014-04-01T00:00:00.000Z",
        "end": "2014-07-01T00:00:00.000Z"
    },
    "bbox": {
        "lowerLeftCoordinate": [3.9662060000000001, 45.9030360000000002],
        "upperRightCoordinate": [19.171284, 51.8473430000000022]
    }
