recalc_snowextent_scene: recalc_snowextent_scene

In SebEagle/snowcoveR: Calculates the snow extent of a Sentinel 2 & Landsat 8 time series and plots the results as 3D-gif animations

Description

This function named 'recalc_snowextent_scene' recalculates snow extent to exclude low probable snow pixels and include high probable snow under cloudcover. For that the previously calculated dem height zone probabilities are used (function 'calc_scene_snowstats')

Usage

recalc_snowextent_scene(store_directory, dem_subdir, height_zone_size,
  threshold1_snow, threshold2_cloud)

Arguments

store_directory	Directory where all satellite scenes are stored in subfolders
dem_subdir	subdirectory, where DEM files are stored
height_zone_size	defines the size (height difference) of the altitudinal zones for which the snowcover percentages are calculated; must be the same size as used in function 'calc_scene_snowstats'
threshold1_snow	set thresholds for heigth zone snow probability, where pixel will be excluded from the class snow
threshold2_cloud	set thresholds for heigth zone snow probability, above which cloud pixels will be added to the class snow
