Paramètre | Explication | Type de données |
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 |
