Raster Statistics

Summary

This function can perform neighborhood calcuation for each cell in a tif format raseter data. The output can be different kinds of statistics of the neighborhood. The statistics include mean, maximum, minimum, range, standard deviation, and sum.

Usage

Click Statistics > Raster Statistics

Settings

• Statistics Type ("Mean" by default): Users can choose any type of statistics in the drop-down menu. The statistics include mean, maximum, minimum, range, standard deviation, and sum.
  • Mean: Calculate the mean value for the neighborhood of each cell to be as the value of the cell at the same location as the orignal cell.
    • Maximum: Calculate the maximum value for the neighborhood of each cell to be as the value of the cell at the same location as the orignal cell.
    • Minimum: Calculate the minimum value for the neighborhood of each cell to be as the value of the cell at the same location as the orignal cell.
    • Range: Calculate the range for the neighborhood of each cell to be as the value of the cell at the same location as the orignal cell.
    • STD: Calculate the standard deviation for the neighborhood of each cell to be as the value of the cell at the same location as the orignal cell.
    • Sum: Calculate the sum for the neighborhood of each cell to be as the value of the cell at the same location as the orignal cell.
• Neighborhood Settings: Settings of the neighborhood size.
  • Height: Height of the neighborhood.
  • Width: Width of the neighborhood.
• Ignore NoData in Calculation (Checked by default): If this option is checked, the software will will ignore the NoData cells in the neighborhoods during the calcuation. If this option is not checked, software will define the cell with NoData in its neighborhood as NoData. If this option is checked, for those NoData cells, the software will calcuate the statistics with the values from their neighborhoods. If the all the cells in the neighborhood of a cell are NoData, whether or not this option is checked, this cell will be defined as NoData during the calculation.
• Output Result: The path for the result of raster statistics.
