NDVI time series extracted from Spot Vegetation data.
The sites of interest are the South Asian study sites of CGIAR
Systemwide Livestock Programme.
A kml file containing the location of the sites can be found at the following path :
SLPSAs_ts is a list containing the 3 following objects :
ts : data frame containing the ndvi time series, one row per time series.
rownames(ts) contains the name of the site and
colnames(ts) contains the time.
period indicates the number of observations per year (period = 36).
Ystart indicates the starting year of the analysis (Ystart = 1999).
