Statistics : The Statistics operator is a plot operator that computes count statistics over - a selection of numerical columns of a single vector dataset, or - multiple raster datasets. The output is a JSON description. For instance, you want to get an overview of a raster data source. Then, you can use this operator to get basic count statistics. ## Vector Data In the case of vector data, the operator generates one statistic for each of the selected numerical attributes. The operator returns an error if one of the selected attributes is not numeric. ## Raster Data For raster data, the operator generates one statistic for each input raster. ## Inputs The operator consumes exactly one vector or multiple raster operators. | Parameter | Type | | ——— | ———————————— | | source | MultipleRasterOrSingleVectorSource | ## Errors The operator returns an error in the following cases. - Vector data: The attribute for one of the given columnNames is not numeric. - Vector data: The attribute for one of the given columnNames does not exist. - Raster data: The length of the columnNames parameter does not match the number of input rasters. ### Example Output json { \"A\": { \"valueCount\": 6, \"validCount\": 6, \"min\": 1.0, \"max\": 6.0, \"mean\": 3.5, \"stddev\": 1.707, \"percentiles\": [ { \"percentile\": 0.25, \"value\": 2.0 }, { \"percentile\": 0.5, \"value\": 3.5 }, { \"percentile\": 0.75, \"value\": 5.0 } ] } }
