Spatio-temporal Adaptive Data Fusion Algorithm for Temperature mapping

This algorithm was developed by Peng Fu and Qihao Weng, Indiana State University.

Language of computer code: MATLAB (R2012 or higher preferred)
Does standalone executable software exist for the algorithm? : No
Input data: Two MODIS images at time t1 and t2 and one Landsat image at t1.
Output: one fine-resolution (Landsat-like) satellite image at t2.
Descriptions of the computer code by the author:
The SADFAT algorithm is designed for predicting land surface temperatures at high temporal frequency and at the medium spatial resolution (120 m) using the combined datasets of MODIS and Landsat (more generally, the combined datasets of MODIS-like and Landsat-like images). SADFAT presented several improvements over its precedents: (1) the incorporation of an ATC model to characterize the annual variations of land surface temperature and to compute conversion coefficient, and (2) the inclusion of linear spectral mixture analysis to address the issue of thermal landscape heterogeneity.
