Land Cover Map Delineation, for Agriculture Development, Case Study in North Sinai, Egypt Using SPOT4 Data and Geographic Information System

In this study, remote sensing and geographic information system (GIS) techniques were used in order to accomplish land cover change of Bozcaada Island, Turkey, by using multitemporal Landsat Thematic Mapper data. Digital image processing techniques were conducted for the processes of image enhancement, manipulation, registration and classification for land cover change analysis. The land cover changes between two different dates were visualized and analyzed by using Geographic Information System techniques. The results showed that remotely sensed data and GIS are effective and powerful tools for carrying out changes on land cover of the island and monitoring of its impact on the environment.

Abstrak Telah dilakukan pemetaan daerah rawan erosi di Kabupaten Timor Tengah Selatan Provinsi Nusa Tenggara Timur dengan menggunakan aplikasi penginderaan jauh dan sistem infomasi geografi. Tujuan dari penelitian ini adalah untuk memetakan daerah rawan erosi dan tingkat kerawanannya di Kabupaten Timor Tengah selatan, Propinsi Nusa Tenggara Timur. Metode penelitian berupa pembuatan peta curah hujan, pembuatan peta tutupan lahan, dan pembuatan peta kelas lereng. Berdasarkan dari hasil penelitian, tingkat rawan erosi dibagi menjadi tiga kelas yaitu: kelas tidak rawan erosi dengan luas wilayah 127.218,69 Ha meliputi kecamatan Noebeba, kecamatan Amanuban Selatan, kecamatan Kualin, sebagian kecamatan Amanuban Timur dan kecamatan Fatukopa. Kelas rawan erosi dengan luas wilayah 251.082,09 Ha meliputi hampir seluruh kecamatan Timor Tengah Selatan dan kelas sangat rawan erosi sekitar 9.125,1 Ha meliputi wilayah kecamatan Fatumnasi, kecamatan Tobu, kecamatan Mollo Utara, sebagian kecamatan Kot’olin. Kata kunci: Peta Rawan Erosi, Penginderaan Jauh, Sistem Informasi Geografi. Abstract We made maps of areas prone to erosion in Timor Tengah Selatan regency, province of East Nusa Tenggara using remote sensing and geographic information system. The purpose of this study is to map areas prone to erosion and risks assessment in Timor Tengah Selatan regency East Nusa Tenggara province .The research methods include the use of GIS to make rainfall, land cover map and class slopes map. Based on the results, level of erosion can be divided into three classes. First, areas which are not prone to erosion (127.218,69 Ha), covering districts Noebeba, districts Amanuban South, districts Kualin, most districts Amanuban East and districts Fatukopa. Second, areas prone to erosion (251.082.09 Ha) covering almost all districts Timor Tengah Selatan. Third, areas highly prone to erosion (9.125,1 Ha) covering an area districts Fatumasi, districts Tobu, Mollo Utara, districts, most districts Kot`olin. Keywords: Erosion hazard map, Remote sensing, Geographic information system.
