A timely and accurate understanding of land cover change has great significance in management of area resources.
To explore the application of a daily normalized difference vegetation index (NDVI) time series in land cover classification, the present study used HJ-1 data to derive a daily NDVI time series by pretreatment.
Different classifiers were then applied to classify the daily NDVI time series.
Finally, the daily NDVI time series were classified based on multiclassifier combination.
The results indicate that support vector machine (SVM), spectral angle mapper, and classification and regression tree classifiers can be used to classify daily NDVI time series, with SVM providing the optimal classification.
The classifiers of K-means and Mahalanobis distance are not suited for classification because of their classification accuracy and mechanism, respectively.
This study proposes a method of dimensionality reduction based on the statistical features of daily NDVI time series for classification.
The method can be applied to land resource information extraction.
In addition, an improved multiclassifier combination is proposed.
The classification results indicate that the improved multiclassifier combination is superior to different single classifier combinations, particularly regarding subclassifiers with greater differences.
