ArcGIS统计矢量内栅格均值（最小值、最大值）邻域统计

ArcGIS统计矢量内栅格均值（最小值、最大值）邻域统计

假如我们要统计矢量内各栅格的均值：

图中的矢量是IPCC提供的全球分区。

栅格是我自己计算得到的热浪频率。

使用以下工具：

这两个工具区别：

• Zonal Statistics生成矢量的栅格化图，含有统计量的属性
• as Table生成一张Table，便于后期转Excel或进行空间链接

这里选择as Table

各参数：

• raster or feature是进行邻域统计的底图，可以是栅格或矢量，这里是矢量
• Zone field指你统计底图的主键
• value raster是待统计的栅格

• 当有空值时，勾选这个可以忽略空值的计算，要勾选

统计的类型有以下几种，一般选择ALL，先看看情况。

Statistic type to be calculated.

• ALL—All of the statistics will be calculated. This is the default.
• MEAN—Calculates the average of all cells in the value raster that belong to the same zone as the output cell.
• MAJORITY—Determines the value that occurs most often of all cells in the value raster that belong to the same zone as the output cell.
• MAXIMUM—Determines the largest value of all cells in the value raster that belong to the same zone as the output cell.
• MEDIAN—Determines the median value of all cells in the value raster that belong to the same zone as the output cell.
• MINIMUM—Determines the smallest value of all cells in the value raster that belong to the same zone as the output cell.
• MINORITY—Determines the value that occurs least often of all cells in the value raster that belong to the same zone as the output cell.
• RANGE—Calculates the difference between the largest and smallest value of all cells in the value raster that belong to the same zone as the output cell.
• STD—Calculates the standard deviation of all cells in the value raster that belong to the same zone as the output cell.
• SUM—Calculates the total value of all cells in the value raster that belong to the same zone as the output cell.
• VARIETY—Calculates the number of unique values for all cells in the value raster that belong to the same zone as the output cell.
• MIN_MAX—Both the minimum and maximum statistics are calculated.
• MEAN_STD—Both the mean and standard deviation statistics are calculated.
• MIN_MAX_MEAN—The minimum, maximum and mean statistics are calculated.

统计结果右键——Open就可以打开看了

然后再导出Excel

大功告成！
