akhdefo_functions.DynamicChangeDetection¶
- akhdefo_functions.DynamicChangeDetection(Path_working_Directory='', Path_UDM2_folder='', Path_to_DEMFile='', Coh_Thresh=0.75, vel_thresh=0.063, udm_mask_option=False, cmap='jet', Median_Filter=False, Set_fig_MinMax=False, show_figure=False, plot_option='origional', xres=10, yres=10)¶
This program calculates optical flow velocity from triplets of daily optical satellite images. Final Timeseris products will be a shapefile format using Time_Series function after stackprep step.
Parameters¶
Path_working_Directory : str
Path_UDM2_folder : str
Path_to_DEMFile : str
Coh_Thresh : float
vel_thresh : float
udm_mask_option : bool
cmap : str
Median_Filter : bool
Set_fig_MinMax : bool
show_figure : bool
- plot_optionstr
“origional”, “resampled”
xres : int
yres : int
Returns¶
- Rasters
velocity in X direction(EW) Velocity in Y direction(NS)
- Figures
Initial Timesereis Figures (those figures are only intermediate products needs calibration)
