    SPLITS (Spline Analysis of Time Series) is a software package to analyze time series of remotely sensed parameters such as vegetation indices.

    Available

    SPLITS is available in Puhti with the following versions:

    • 1.11
    • 1.10

    Usage

    SPLITS is included in the splits module. The gcc module needs to be loaded also. You can load these with

    module load gcc splits/<VERSION_NUMBER>

    Using SPLITS

    SPLITS is a command line tool. The following commands are available

    • peakcal - analyze the structure of bottoms and peaks in a phenological time series
    • phencal - calculate phenological parameters from a fitted spline model
    • prepro - preprocess MODIS data to be used with SPLITS
    • splcal - use a fitted spline model to interpolate data
    • splfit - fit a spline model to a time series image
    • splview - graphical user interface for spline model exploration
