Often, the only information available consists of coarse class fraction data, typically obtained through spectral unmixing. This paper shows how to integrate, in addition to such coarse fractions, class labels at a set of fine pixels obtained independent of the satellite sensor measurements. The integration of such fine spatial resolution information is achieved within the Indicator Kriging formalism in either a prediction or simulation mode. The spatial dissimilarity or texture of class labels at the fine (target) resolution is quantified in a non-parametric way from an analog scene using a set of experimental indicator semivariogram maps. The output of the proposed procedure consists of maps of probabilities of class occurrence, or of a series of simulated class maps characterizing the inherent spatial uncertainty in the super-resolution mapping process. | URI: | https://hdl.handle.net/20.500.14279/8681 | ISSN: | 00991112 | DOI: | 10.14358/PERS.73.8.913 | Rights: | © American Society for Photogrammetry and Remote Sensing | Type: | Article | Affiliation : | Stanford University University of California |
