Abstract | Monitoring crops area is essential in achieving food security. The production coverage, crop types, and their growth phases are the key for monitoring food supply. Remote sensing plays a critical role to provide reliable data on regional basis supporting food production monitoring. In this research, we evaluated the use of Phased Array-type L-band Synthetic Aperture Radar (PALSAR-2), coupling with selected machine learners to map crop areas in the South Burnett, Queensland, Australia. Feature amendments onto dual polarimetric of ALOS PALSAR-2 were then assessed by means of variable importance to improve classification performance. Four machine learners were selected based on previous research and evaluated through classification accuracy. The best performer was Random Forest followed by C5.0, which generated accuracy at 82% and 81%, respectively. The response of data amendment varied over different classifiers. Random Forest and C5.0 seem to produce the highest accuracy at the best data-subset, while additional features with contribution less than 20% tended to reduce the accuracies of the two classifiers. Meanwhile, extreme gradient boosting tree and support vector machine kept increasing their accuracies, although additional features contributed trivially. |
