UP42 Time Series Image Statistics

Apply image statistics on a stack of rasters


Introduction

This block mainly works with time series of images with one band, such as images related to weather or climate analysis, and specifically works with Sentinel-5P Level-3 (GeoTIFF). For more information, please read the block description.

Block type: PROCESSING

Supported parameters

This block applies statistics on a stack of raster inputs and creates a raster file containing the result. The statistics can be one of the following: mean, min, max, std, median, or sum. For instance, by using mean, the mean of its values for each pixel in the stack will be calculated. This stack of raster inputs is essentially a time series of images for a specific area of interest.

  • method: A statistical method to be applied on the stack of raster inputs. Default is mean.
