[GRASS-user] About Spatial PCA in GRASS

[Shiva Khanal]

Hi,

I am interested to run the spatial-mode PCA on raster time series. In R it is implemented as an ‘EOF’ function in spacetime Package. The function transposes the raster stack and applies ‘prcomp’ function.  I would like to know if there is any possible way to implement i.pca similar to this approach.

Interestingly, I found a very good tutorial on GRASS raster time series at https://grasswiki.osgeo.org/wiki/Temporal_data_processing/GRASS_R_raster_time_series_processing This includes the example using spacetime package to read GRASS raster time series into R.

I would very much appreciate any support on this.

Thank you.
