N2  - Spatio-temporal prediction and forecasting of land surface temperature (LST) are relevant. However, several factors limit their usage, such as missing pixels, line drops, and cloud cover in satellite images. Being measured close to the Earth's surface, LST is mainly influenced by the land use/land cover (LULC) distribution of the terrain. This article presents a spatio-temporal interpolation method which semantically models LULC information for the analysis of LST. The proposed spatio-temporal semantic kriging (ST-SemK) approach is presented in two variants: non-separable ST-SemK (ST-SemKNSep) and separable ST-SemK (ST-SemKSep). Empirical studies have been carried out with derived Landsat 7 ETM+ satellite images of LST for two spatial regions: Kolkata, India and Dallas, Texas, U.S. It has been observed that semantically enhanced spatio-temporal modeling by ST-SemK yields more accurate prediction results than spatio-temporal ordinary kriging and other existing methods.
