Developing new spectral indices for karst rocky desertification monitoring in Southwest China
2009
2009 IEEE International Geoscience and Remote Sensing Symposium
Preserved Fulltext
In this study, we developed new spectral indices, karst rocky desertification synthesis indices (KRDSI), were then designed based on tied-spectrum permutation and unique spectral characteristics of main ...
Our study indicates that KRDSI is a useful tool for karst rocky desertification monitoring with remotely sensed data. ...
The principal objective of this study is thus to develop and evaluate new spectral indices for karst rocky desertification in Southwest China. ...
