%AUTOPREPAREDATAARD Prepare Landsat Surface Reflectance into CCDC format,
% which are downloaded from USGS Earth Resources Observation and Science
% (EROS) Center Science Processing Architecture (ESPA)
% (https://espa.cr.usgs.gov/)
%
% AUTOPREPAREDATAARD() automatically prepares all Landsat ESPA product in
% the current folder into CCDC format.
% AUTOPREPAREDATAARD(PARAM1,VAL1,PARAM2,VAL2,PARAM3,VAL3,PARAM4,VAL4) specifies
% parameters that control input and outout directory, the clear pixel
% filter condition, and sample file (used to restrict same extent using
% nearest method based on the Topotoolbox
% https://topotoolbox.wordpress.com/topotoolbox/).
%
% Data Support
% -------------
% The input data must be of class .tif or .img. Only .tif format can be
% resamlped to a same extent.
%
%
% Specific parameters
% ------------------------
% 'InDir' Directory of input data. Default is the path to
% the current folder.
% 'OutDir' Directory of output data. Default is the path to
% the current folder.
% 'ExtentSample' An example geotiff file, of which extent will be
% used as basic reference. All images will be
% resampled to this same extent. Default is not to
% do this process if no input for this.
% 'ClrPixPer' Percentage of mininum clear pixels
% (non-ice/snow covered). Unit is %. Default is '20'.
