In sitsfeats: Satellite Image Time Series Features

Description

The package sitsfeats provides a set of basics metrics:

• The max_ts() retrieves the maximum value contained in the time series.

• The min_ts() retrieves the minimum value contained in the time series.

• The mean_ts() retrieves the mean value of the time series.

• The median_ts() retrieves the median value of the time series.

• The sum_ts() retrieves the sum of all time series points.

• The std_ts() retrieves the standard deviation of the time series.

• The skew_ts() retrieves the skewness of the time series.

• The kurt_ts() retrieves the kurtosis of the time series.

• The amplitude_ts() retrieves the amplitude of the time series.

• The fslope_ts() retrieves the first slope of the time series.

• The abs_sum_ts() retrieves the absolute sum of the time series points.

• The amd_ts() retrieves the absolute mean of the difference between each point in the time series.

• The mse_ts() retrieves the mean spectral energy of the time series.

• The fqr_ts() retrieves the value of the first quartile of the time series (0.25).

• The sqr_ts() retrieves the value of the second quartile of the time series (0.50).

• The tqr_ts() retrieves the value of the third quartile of the time series (0.75).

• The iqr_ts() retrieves the interquartile range (difference between the third and first quartile).
