R package for Raster Time Series Analysis

The package provides a collection of analytics to perform spatio-temporal analysis from raster time series. It acts as a front-end to already available functions in various R packages, specifically designed to handle geographic datasets provided as raster time series. The available functions within the package allow the direct input of raster time series to extract concise and comprehensive information. Since some techniques for spatio-temporal analysis can not deal with missing values raster time series, a selection of gap-filling methods are provided.

Main features:

• use of raster time series with explicit temporal dimension
• use of raster time series as direct input to functions
• use of a raster mask to select the region of interest and reduce memory loads
• parallel processing using multiple CPUs

Supported gap-filling methods:

• DINEOF
• linear interpolation
• spline interpolation
• stine interpolation

Currently, the following analytical methods are supported:

• Empirical Orthogonal Function
• Empirical Orthogonal Teleconnections
• Seasonal Trend Decomposition using Loess
• X-11
• X-13-ARIMA seasonal adjustment
• Mann-Kendall trend test

The following analytical methods will be supported soon:

• Self Organizing Maps
