Klasifikasi Tutupan Lahan Wilayah Peri-Urban Berdasarkan Ciri Tekstur Menggunakan Data Terrasar-X

Abstract

Peri-urban is developed in urban or metropolitan fringe. The area has particular characteristics such as scattered settlements, slightly urbanized, fast population growth and a tendency of environmental degradation. Monitoring in this area is then required, especially to assess agricultural land conversion. This paper discusses an application of dual-polarized TerraSAR-X Spotlight Mode to retrieve various land cover in Sidoarjo, East Java. Specifically, the research studied discrimination among water bodies, rice fields, settlements, woody vegetation and industrial parks at X-band. The research compiled tonal and textural information from those land cover types and fed those signatures into statistical analysis. Decision tree classification method is applied to classify and to find most informative features. The results suggested that TerraSAR-X has capability to distinguish some land cover features; nonetheless, some objects could not have specific tonal/textural signatures, making them hard to classify.
