Downscaling plays an important role in comparison,integration of disparate datasets and calibration,validation of models in a range of applications.Firstly,the general formulation of geostatistical-based downscaling through the use of area\|to\|area,area\|to\|point and point-to-point covariances in the kriging system will be briefly descrebed.In the next section,a basic idea of conducting point support variogram from geographical units with different sizes and shapes is given.After that the principles and cases about geostatistical-based downscaling methods were developed in recent years that would be introduced.Area\|to\|area and area\|to\|point kriging could be used without auxiliary data and efforts to find a method which provides better prediction for supplementary information is tried.Finally,trends and some basic questions of methods proposed recently are discussed in the conclusion.

Key words:  Downscaling      Area to point      Area to area      Geostatistics      Kriging      Deconvolution
