Abstract

Pembangunan wilayah yang cepat di kota Jakarta diindikasikan dengan peningkatan jumlah wilayah terbangun, seperti perumahan, jalan, dan bangunan komersial dan lainnya. Identifikasi tutupan lahan yang cepat dan terbaru serta informasi perubahannya sebagai data utama dalam merencanakan pembangunan sangat dibutuhkan. Salah satu metode untuk pemetaan tutupan lahan dan perubahannya diperoleh melalui pemanfaatan data penginderaan jauh yang memiliki sifat kontinu, dapat mencakup wilayah yang luas, serta effisien. Data penginderaan jauh yang digunakan meliputi citra optis dan radar. Data radar memiliki keunggulan dalam memetakan tutupan lahan dan perubahannya yang tidak terkendala waktu dan cuaca. Pada awal tahun 2018, data radar TerraSAR-X (TSX) telah dapat di akusisi di stasiun bumi LAPAN Parepare. Penelitian ini menggunakan citra TSX mode Stripmap dengan resolusi spasial 3 m dan waktu yang digunakan adalah tahun 2010 and 2013, yang digunakan untuk deteksi penutupan lahan dan perubahannya di kota Jakarta menggunakan metode texture analisis dan segmentasi. Akurasi assessmen akan dilakukan menggunakan citra Pleiades dan Google Earth. Hasil yang diperoleh adalah citra TSX dapat mengidentifikasi perubahan lahan di kota Jakarta, yaitu perkembangan permukiman, pembangunan jalan baru dan informasi tentang berkurangnya area lahan terbuka hijau.

Abstract

Pemanfaatan data resolusi spasial sangat tinggi seperti Pleaides saat ini mengalami permintaan yang tinggi. Salah satu pemanfaatan data ini untuk mendukung kebencanaan, dimana proses pengolahan otomatisasi dan cepat sangat diperlukan dan tidak terhindarkan. Citra Pleiades telah diakusisi oleh stasiun bumi LAPAN di tahun 2018. Penelitian ini mengkaji tentang peningkatan kualitas geometri citra Pleiades dengan metode titik ikat bundle adjustment (BA) untuk proses mosaik dengan wilayah studi di wilayah Kabupaten Madiun dan Magetan. Metode ini menggunakan parameter keterkaitan geometri antar scene. Keterkaitan tersebut dihubungkan dengan membuat titik ikat. Titik-titik ini berada di area pertampalan antar scene. Citra hasil proses koreksi geometri BA akan dilakukan penilaian kualitas hasil koreksi geometrinya dengan membandikan data koordinat pengukuran lapangan. Hasil penilaian kualitas akurasi koreksi geometri menunjukkan bahwa koreksi geometri menggunakan metode BA lebih mendekati titik koordinat pengukuran lapangan dibandingkan koreksi geometri tanpa BA.

Abstract

Recently, the utilization of very high spatial resolution data such as Pleaides has reached at a high demand. Particularly to support disaster mitigation, where automation and fast image processing are necessary and unavoidable. Pleiades imagery has been acquired at LAPAN ground station starting in 2018. This study examines the improvement of the Pleiades images geometry accuracy processed using the bundle adjustment (BA) method in order to support image mosaicking where case study is located in the Madiun regency and the Magetan regency. This method uses parameters to relate the geometry between scenes by using tie points. These points are located in the intersection area between scenes. Geometry quality assessment of the imagery produced using BA correction are measured by comparing between the coordinate of the imagery and the coordinates obtained from the field measurement. The assessment shows that BA geometry correction has improved the geometry quality of the images which nearly similar to the field measurement and achieved a better geometry accuracy compare to the images processed without BA method.

Abstract

The use of remote sensing in vegetation monitoring has been widely applied, including vegetation density monitoring. However, the use to evaluate rehabilitation program on critical land is still limited. Evaluation of forest cover and land rehabilitation activities become important due to the increase of critical land. The current method to evaluate the land condition is conducted by ground check at the rehabilitation site held at the end of the year after the initial implementation of the rehabilitation program until the third year. This method requires a lot of time, labour, and money. Based on the standard regulation to evaluate the rehabilitation program, the program is successful if 90% the new vegetation planted can grows until the third year. Therefore, this research uses an effective and efficient method for evaluating land rehabilitation programs using remote sensing data by understanding vegetation conditions and their densities using multi-temporal analysis for large areas. A multi-temporal Landsat-8 images from 2015-2018 will be used to analyze the Normalized Difference Vegetation Index (NDVI) trend in the time-based sequence method using spatial analysis. The results show that the non-forest area in Serayu Hulu Watershed consist of non-critical land, moderate critical land, critical land, and severe ciritical land. According to the ground check and NDVI trend analysis, the rehabilitation in non-critical land of the non-forest area was generally unsuccessful due to the area rehabilitation plant were harvested before the rehabilitation evaluation time ended. On the otherhand, on critical land; moderate critical land; and severe critical land of the non-forest area, the success of rehabilitation program was indicated by the achievement of the NDVI threshold value at 0.4660; 0.4947. 0.4916, respectively.

Abstract

Rapid urban growth in Jakarta is indicated by the increases of building area, such as settlements, roads, commercial and others. Identification of land cover extent and its changes is a vital data for urban planning. One method for land cover mapping and its changes is obtained by the utilization of remote sensing data that characterize as having a continuity data, covers a vast area, and cost-effective. Remote sensing data can be obtained from optical and radar imagery. Radar data importance for mapping land cover and land cover changes because radar data does not constrain by time and weather. In early 2018, the TerraSAR-X (TSX) data can be acquired at the LAPAN Parepare ground station. This research uses the TSX Stripmap image mode with a spatial resolution of 3 m in 2010 and 2013. The TSX data will be used to map the land cover and land cover changes in Jakarta using method of the texture analysis and image segmentation. The accuracy assessment of the map will be assessed visually and quantitatively using the Pleiades images (0.5 m) and Google Earth images. The results show that the TSX images detect the current developments of settlements, new roads construction and provide information on the loss of green open space in Jakarta.
