Abstract


Abstrak Tingginya kebutuhan informasi tutupan lahan dalam berbagai sektor perencanaan dapat disediakan secara time-and-cost effective melalui analisa citra penginderaan jauh, diantaranya menggunakan OBIA (object based image analysis). Teknik tersebut banyak diterapkan pada berbagai macam citra, baik resolusi spasial tinggi maupun menengah. Namun studi komparasi pada citra resolusi spasial yang berbeda masih belum banyak dilakukan secara comparable, dimana umumnya terdapat banyak perbedaan variable komparasinya. Penelitian ini bertujuan untuk membandingkan secara langsung penerapan OBIA terhadap resolusi spasial citra yang berbeda dengan membatasi variable berpengaruh terhadap akurasi, diantaranya: klasifikasi jenis tutupan lahan, saluran masukan citra, dan kriteria serta teknik klasifikasi OBIA. Berdasarkan studi komparasi, diketahui bahwa penggunaan Pleaides memberikan akurasi yang lebih tinggi dibanding Landsat-8 OLI namun memerlukan strategi klasifikasi yang lebih rumit. Sedangkan ditinjau dari overall accuracy dan indeks kappa, disimpulkan bahwa OBIA mampu memberikan akurasi hasil yang termasuk dalam acceptable thresholds untuk derivasi tutupan lahan menggunakan citra resolusi spasial tinggi ataupun menengah.


Abstract The high demand for land cover information for vast planning sectors could be provided in time-and-cost-effective techniques using remote sensing image analysis, including employing OBIA (object based image analysis). The technique is widely applied to various kinds of imageries, for high and medium spatial resolution as well. However, comparative studies on the usage of different spatial resolution imageries have not been carried out in a comparable condition, where several variables could be in different terms. The study aims is to straightly compare OBIA’s application in diverse spatial resolution of imagery by limiting the affecting variables to its accuracy, including classification of land cover schemes, imagery channels input, and OBIA’s criteria and techniques. The comparative study reveals the usage of Pleaides provides higher accuracy than Landsat-8 OLI but requires a more complicated classification strategy. Meanwhile, the overall accuracy and kappa index of both maps exposes that OBIA could provide scientifically acceptable accurate land cover maps derived from both high and medium spatial resolution imagery.
