Abstract

Quality of accuracy and precision is the main problem in survey and mapping. One of the problems in remote sensing is the geometrical correction using the orthorectification of the satellite imagery. Conceptually, it is the same with the orthorectification of oblique air photos. This research study is about how to orthorectify the SPOT5 imagery of Semarang using DMP and RPCs methods. SPOT5 satellite can acquire data with a sensor angle up to 200, so it produces oblique images. This DMP method use the Colinear equation with the condition of Polynomial order 2 (horizontal) and the height value was obtained from Digita Terrain Model (DTM). RPCs methods use parameters of interior orientation of its metadata and are also assissted by eight ground control points from DTM. Adjustment computation is used to compute the differential orthoimage model to produce new parameter values that will be used for orthorectification. This result of orthorectification is tested by overlaying toward the Indonesian Topography Map (RBI) scale 1:25.000 and the ground survey. Keywords: SPOT5, Orthorectification, DMP, RPCs

Abstract

Three methods of atmospheric correction, Second Simulation of the Satellite Signal in the Solar Spectrum (6S), Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS) and the model Fast Line-of-sight Atmospheric Analysis of Spectral Hypercubes (FLAASH), have been applied to the level 1T Landsat-7 image Jakarta area. The atmospheric corrected image is then compared with the TOA reflectance image. The results show that there is an improvement of the spectral pattern on the TOA reflectance image by the decrease of the reflectance value of each object by (1 - 11) % after the atmospheric correction of all models for visible bands (blue, green and red). In the NIR and SWIR bands there is an increase in the spectral value of about 1% to the TOA reflectance on all objects except wetland for the LEDAPS model. The percentage of the increase and the decrease in spectral values of 6S and FLAASH models have the same tendency. Analyzes were also performed on the NDVI values of each model, where NDVI values were relatively higher after atmospheric correction. The NDVI value of rice crop on FLAASH model is the same as 6S model that is equal to 0.95 and for wetland, it has the same value between FLAASH model and LEDAPS which is 0.23. NDVI value of entire scene for FLAASH model = 0.63, LEDAPS model = 0.56 and 6S model = 0.66. Before the atmospheric correction, the TOA is 0.45. Abstrak Tiga metode koreksi atmosfer diantaranya  Second Simulation of the Satellite Signal in the Solar Spectrum (6S), Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS) dan model Fast Line-of-sight Atmospheric Analysis of Spectral Hypercubes (FLAASH) telah diterapkan pada citra Landsat-7 level 1T wilayah Jakarta. Citra yang telah terkoreksi atmosfer dibandingkan dengan citra reflektan TOA. Hasilnya menunjukkan bahwa terdapat perbaikan pola spektral pada citra reflektan TOA dengan adanya penurunan nilai reflektan setiap obyek sebesar (1 – 11) % setelah dilakukan koreksi atmosfer pada semua model untuk kanal-kanal visible (blue, green dan red). Pada kanal NIR dan SWIR terjadi kenaikan nilai spektral yaitu sekitar 1% terhadap reflektan TOA pada semua objek terkecuali objek lahan basah untuk model LEDAPS. Persentase kenaikan dan penurunan nilai spektral model 6S dan FLAASH memiliki kecenderungan yang sama. Analisis juga dilakukan terhadap nilai NDVI masing-masing model, dimana nilai NDVI relatif lebih tinggi setelah koreksi atmosfer. Nilai NDVI tanaman padi pada model FLAASH sama dengan model 6S yaitu sebesar 0.95 dan untuk lahan basah memiliki nilai yang sama antara model FLAASH dan LEDAPS yaitu 0.23. Nilai NDVI seluruh scene untuk model FLAASH = 0.63, model LEDAPS = 0.56 dan model 6S = 0.66. Sebelum koreksi atmosfer (TOA) adalah 0.45.

Abstract

Metode Gross Primary Production (GPP) dikembangkan sebagai salah satu pendekatan perhitungan cadangan karbon yang tersimpan dalam vegetasi. Salah satu produk GPP yang secara operasional dapat diunduh secara cuma-cuma adalah MOD17 yang diperoleh dari Satelit Terra/Aqua MODIS, NASA. Mengingat produk ini masih bersifat global, maka upaya pengujian perlu dilakukan di beberapa tipe ekosistem. Baru-baru ini, NASA telah meluncurkan produk versi baru yang pengujiannya belum banyak dilakukan di hutan tropis, khususnya di wilayah Indonesia. Dalam penelitian ini dilakukan evaluasi MODIS GPP versi baru (MOD17A2-51) di hutan rawa gambut, Provinsi Kalimantan Tengah, menggunakan analisis time series dan uji statistik data lapangan (GPP_EC). Hasil penelitian menunjukkan bahwa data 8-harian MODIS GPP memiliki pola time series yang hampir sama dengan MOD-EC meskipun secara statistik memberikan korelasi yang kurang baik. Secara umum, MODIS GPP cenderung memiliki nilai yang lebih rendah dibandingkan GPP_EC baik pada musim hujan maupun pada musim kemarau. Sebaliknya, pada musim kemarau yang sangat panjang, seperti pada tahun 2002 akibat ENSO, nilai MODIS GPP cenderung overestimate dibandingkan GPP_EC. Walaupun demikian, nilai akumulasi GPP dengan mempertimbangkan musim (kemarau dan hujan) menunjukkan hubungan yang baik (r=0.94, RMS= 17.47, and Efficiency score= 0.68). Periode musim kering ke-2 (Agustus-Oktober) menunjukkan distribusi nilai yang lebih baik dibandingkan periode musim lainnya. Penelitian ini dapat menyimpulkan bahwa MODIS GPP versi 51 dapat digunakan untuk pemantauan kandungan biomasa berdasarkan musim di hutan rawa gambut tropis Indonesia.

Abstract

An image is often corrupted by a noise in its acquisition and transmission. A high resolution remote sensing data will be seen more roughly if it is corrupted by a noise. Wavelet is one of the fascinating denoising manners that will be used to solve this problem. The main application of the Stationary Wavelet Transform (SWT) is denoising. The principle is the average of several denoised signals. Each of them is obtained by using the usual denoising scheme, but it is applied to the coefficients of a ε-decimated DWT. The stationary wavelet transform (SWT) is to make the wavelet decomposition time invariant. This improves the power of wavelet in the signal denoising. In this research, we apply the SWT method to preprocess the remote sensing data for removing the noise. The Worldview-1 satellite data is used in this research. The sensor resolution is 0.55 meters and Ground Sample Distance (GSD) at 20º off-nadir. The Area of Interest (AoI) is Monas, Jakarta and the acquisition of the data was done on March 13th, 2008. For the data analysis, the Worldview-1 satellite data is added by the noise. The result of this research is that the noise can be removed by SWT method. By using structural similarity index (SSIM), the quality of the denoised images by SWT, Wavelet Transform 2D and Wavelet Packet 2D are 0.2666, 0.1912, and 0.1927, respectively. Thus, the SWT provides a better performance in denoising the remote sensing data than Wavelet Packet 2 D and Wavelet 2D methods. Keyword: Denoising, Remote sensing data, Stationary wavelet transform

Abstract

The water content of peatland ecosystems stored as gasses in the air and as liquid in the peat soil and vegetation. The presence of water was influential to the value of spectral radians received by satellite sensors. Objective of study were develop empirical model to be applied in the Landsat 8 satellite imagery interpretation to estimate water content of peatland ecosystem. Method consisted of field measurements and satellite data interpretation. Field activities aimed to obtain weather parameters such as radiation, air temperature, surface temperature, evapotranspiration (ET), relative humidity (RH), soil water content (KAT), and biomass for each land cover in peatland ecosystems. Field measurements results were used to validate the parameters derived from Landsat 8 satellite data. Water content in the air was assessed by the ET and RH, in the soil was assessed by soil heat flux (G) and in the vegetation by biomass. The results of the validation of the data field measurement with Landsat 8 showed only ET (r2 = 0.71), RH (r2 = 0.71), and biomass (r2 = 0.87) had a strong relationship, while between G and KAT had weak relationship. Conclusion of this study indicated Landsat 8 satellite data could be used to calculate the water content in the air and vegetation. Thus, estimating water content in the peatland ecosystem with satellite data can only be done on the surface. AbstrakEkosistem lahan gambut menyimpan air dalam bentuk gas di udara, dan cair dalam tanah gambut dan vegetasi. Keberadaannya mempengaruhi nilai spektral radians yang diterima oleh sensor satelit. Tujuan penelitian ini adalah untuk mendapatkan model empirik yang dapat diaplikasikan untuk interpretasi citra satelit dalam pendugaan jumlah air di ekosistem lahan gambut. Metode penelitian terdiri dari pengukuran lapangan dan interpretasi data satelit LANDSAT 8. Parameter cuaca seperti radiasi, suhu udara, suhu permukaan, evapotranspirasi (ET), kelembaban udara (RH), kadar air tanah (KAT) dan biomassa diukur di lapangan pada setiap jenis tutupan lahan. Hasil-hasil pengukuran lapangan digunakan untuk memvalidasi parameter-parameter yang diturunkan dari data satelit LANDSAT 8. Jumlah air di udara yang dinilai dari ET dan RH, jumlah air di tanah dinilai dengan laju pemanasan tanah (G) dan jumlah air di vegetasi dengan biomassa. Hasil validasi antara data lapangan dengan data LANDSAT 8 menunjukkan hanya nilai ET (r2=0,71), RH (r2=0,71), dan biomassa ((r2=0,87) mempunyai hubungan yang kuat, sedangkan nilai G tidak mempunyai hubungan yang kuat dengan KAT. Penelitian ini menyimpulkan bahwa data satelit LANDSAT 8 hanya dapat digunakan untuk menghitung jumlah air yang tersimpan di udara dan vegetasi. Oleh karena itu, pendugaan jumlah air di ekosistem lahan gambut dengan data satelit hanya dapat dilakukan di atas permukaan.

Abstract

Simulation of eruption material flow using probabilistic model based on the Monte Carlo algorithm was conducted in this research. The simulation result was used to support the creation of zoning map of volcanic hazards and the estimation of building number which has possibility to be impacted by the Merapi Volcano eruption. Input data for the simulation was Digital Elevation Model - Shuttle Radar Topographic Mission (DEM-SRTM) with a spatial resolution of 30 meters. In addition, GeoEye satelit imagery in 2009 was used to renew settlement information of the RBI map from BAKOSURTANAL. The simulation result of material flow eruption was overlaid with building area information to estimate the magnitude of eruption impact. The simulation results from this research has similar pattern and similar eruption material distribution with the reference map (volcanic hazard map of Merapi). The flow of Merapi eruption material generally leads to the south through the Gendol Rivers to Cangkringan, and to the southwest ward through the Putih Rivers to Srumbung. Material flow eruption is shown in height simulations 2 meters and 7 meters. The wider and widening of the of simulation models material flow eruption generated, the greater impact on the settlements in the vicinity of Merapi Volcano.

Abstract

Clay minerals in the oil and gas field have changed with an increase of the quantities in the middle of the oil and gas field and reduction in the edges. This reduction is the effect of micro seepage from oil and gas from the subsurface. The aims of the research is to identify the potential oil and gas seepage through clay mineral mapping. The data used where Landsat 8 OLI/TIRS with recording dated September 25, 2015. The method used in the mapping of clay minerals using the ratio of 1.55-1.75 µm (Short Wave Infrared 1) and 2.08-2.35 µm (Short Wave Infrared 2). The result of Landsat 8 OLI/TIRS data processing shows the potential of anomalies in edges of the oil and gas field. The anomaly is a change in the index value of clay minerals that tend to be lower with values 1.0 to 1.5 than the middle of oil and gas field with values 1.5 to 2.0. The potential pattern of the anomaly follows the border of the oil and gas field. Field surveys show that oil and gas field based on grain size analysis is dominated by clay-sized soil. The dominant clay minerals from X-Ray Diffraction analysis are smectite (56%) and kaolinite (6%).ABSTRAKMineral lempung di lapangan migas mengalami perubahan dengan terjadinya peningkatan kandungannya pada tengah lapangan migas dan pengurangan di tepinya.

Abstract

Tsunami disaster caused great damages and very large victims especially when occurs in urban area along. Therefore information of evacuation in a map is very important for disaster preparedness in order to minimize the number of victims in affected area. Here, information generated from remote sensing satellite data (Landsat, SPOT-5 nad DEM) and secondary data (administration boundary and field survey data) are used ti simulate evacuation route and to produce a map for Padang City. Vulnerability and evacuation areas are determined based on information of maximum tsunami height in shoreline and topography condition. Landuse/landcover and infrastructure (road, bridge and building) are extracted from SPOT data. All the data obtained from remote sensing and secondary data are integrated using geospatial modeling to simulate tsunami evacuation routes. The simulation of evacuation route in Padang City for tsunami preparedness is provided by considering river line, shelters and save zone, available infrastructur (road), the shortest distance (to shelters and save zone) and local community experiences.
