e-sensing Software

R packages

We have produced dtwSat , an R package that implements the time-weigthed dynamic time warping algorithm. The method improves on the well-known dynamical time warping (DTW) method for time series data mining. We introduce a temporal constraint that accounts for the agricultural calendar. The resulting algorithm achives better results than previous research that has used DTW for remote sensing image classification.

Github site

Our github site has a number of useful tools for management of Earth Observation data in array databases, including code for extracting, transforming and loading data in SciDB, and the code for the Web Time Series Service.
