abstract = "This paper explores the use of ALOS (Advanced Land Observing
Satellite) PALSARL-band (Phased Array type L-band Synthetic
Aperture Radar) and RADARSAT-2 C-band data for land-cover
classification in a tropical moist region. Transformed divergence
was used to identify potential textural images which were
calculated with the gray-level co-occurrence matrix method. The
standard deviation of selected textural images and correlation
coefficients between them were then used to determine the best
combination of texture images for land-cover classification.
Classification results based on different scenarios with maximum
likelihood classifier were compared. Based on the identified best
scenarios, different classification algorithms maximum likelihood
classifier, classification tree analysis, Fuzzy ARTMAP (a
neural-network method), k-nearest neighbor, object-based
classification, and support vector machine were compared for
examining which algorithm was suitable for land-cover
classification in the tropical moist region. This research
indicates that the combination of radiometric images and their
textures provided considerably better classification accuracies
than individual datasets. The L-band data provided much better
landcover classification than C-band data but neither L-band nor
C-band was suitable for fine land-cover classification system, no
matter which classification algorithm was used. L-band data
provided reasonably good classification accuracies for coarse
land-cover classification system such as forest, succession,
agropasture, water, wetland, and urban with an overall
classification accuracy of 72.2%, but C-band data provided only
54.7%. Compared to the maximum likelihood classifier, both
classification tree analysis and Fuzzy ARTMAP provided better
performances, object-based classification and support vector
machine had similar performances, and k-nearest neighbor performed
poorly. More research should address the use of multitemporal
radar data and the integration of radar and optical sensor data
for improving land-cover classification.",
