StatisticsHistogram (raster, statistics, histogram)

パラメーター	説明	データ タイプ
raster	The input raster.	Raster
statistics	List of statistical information, based on predefined statistics for each band. Statistics specified for a single-band raster are, for example: statistics = [{"min": 0, "max": 23.06, mean": 4.547517, "standardDeviation": 2.6870, "count": 10000, "median": 5, "mode": 6}]. Statistics specified for a three-band raster are, for example: statistics = [{"min": 0, "max": 23.06, "mean": 4.547517, "standardDeviation": 2.6870, "count": 10000, "median": 5, "mode": 6}, {"min":2, "max": 25, "mean": 5.32, "standardDeviation": 3.42, "count": 10000, "median": 6, "mode": 6}, {"min": 5, "max": 53.06, "mean": 35.23, "standardDeviation": 6.3270, "count": 10000, "median": 36, "mode": 6}].	List
histogram	Dictionary of histogram information, based on predefined histogram for each band. Enter the dictionary of histogram information using the example below: { "rasterFunction": "StatisticsHistogram", "rasterFunctionArguments": { "histograms": [{ "size": 256, "min": 0, "max": 23.064547032777931, "counts": [559, 172, 217, ... //256 elements for each of the bins in this example ] }]	Dictionary

戻り値

データ タイプ	説明
Raster	The output raster with the statistics and histogram defined.
