ltsk library is a collection of programs for implementing local spatial and local spatiotemporal Kriging. Unlike global Kriging, ltsk subsets the sample around a given location and time where predicted is needed; estimates variogram using the subset of sample data. Product-sum model is implemented and automatically estimated using the data points within the local neighbourhood. A unique advantage of ltsk is that it addresses non-stationarity, which is difficult to handle in large spatiotemporal dataset.
