The use of Sentinel-1 (S1) radar for wide-area, near-real-time (NRT) tropical-forest-change monitoring is discussed, with particular attention to forest degradation and deforestation. Since change can relate processes ranging from high-impact, large-scale conversion low-impact, selective logging, occur in sites having variable topographic environmental properties such as mountain slopes wetlands, a single approach insufficient. system introduced here combines time-series analysis small...
Jakarta faces a critical challenge of extensive land subsidence, ranking prominently globally. This research employs combined technical and policy evaluation approach to analyze the issue, incorporating sustainability considerations assess efficacy Governor Regulation Number 93 2021, focusing on how groundwater-free zone relates subsidence in city. We processed 81 ALOS-2 PALSAR-2 synthetic aperture radar (SAR) data using persistent scatterer interferometric (PS-InSAR) with HH polarization...
Forest and land fires are disasters that greatly impact various sectors. Burned area identification is needed to control forest fires. Remote sensing used as common technology for rapid burned identification. However, there not many studies related the combination of optical synthetic aperture radar (SAR) remote data detection. In addition, SAR has advantage being a can be in weather conditions. This research aims evaluate model using hybrid convolutional neural network (CNN) feature...
Flooding in urban areas is counted as a significant disaster that must be correctly mitigated due to the huge amount of affected people, material losses, hampered economic activity, and flood-related diseases. One technologies available for mitigation prevention satellites providing image data on previously flooded areas. In most cases, floods occur conjunction with heavy rain. Thus, from satellite’s optical sensor, flood area mostly covered clouds which indicates ineffective observation....
The North Java coastal area, known as the Pantura region, is experiencing significant land subsidence, with certain areas sinking up to 10 cm per year. Pekalongan among most affected, subsidence rates between and 19 annually, mainly due groundwater extraction, sediment compaction, erosion. Other cities, like Semarang Demak, show averaging 4 This rapid favorable geological conditions ongoing urban development. study investigates in using PS-InSAR method dynamic visualization of time-series...
Abstract A series of floods occurred in the early year 2021 are first major South Kalimantan flood past fifty years. The regions which were affected by them Banjarmasin, Central Hulu Sungai Regency, and Tanah Laut. There 211,670 people severely flooding some need to be evacuated higher zones. Not only as a concern Indonesia National Disaster Management Authority (BNPB) but also earthquake that struck Mamuju Majene province West Sulawesi on 14 15 January 2021. Damage was reported 4 regencies...
Forest and field fires have become a frequent phenomenon in recent years caused by human activities Indonesia, affecting all forms of forest cover. fire-degraded land is more prone to burn again, due the nature peatland Kalimantan. Rapid mapping technology for burnt areas affected needed obtain this information. The use remote sensing technology, form synthetic aperture radar (SAR) images, combined with cloud computing processing speeds up data not existing Quick-Mapping employed research...
Abstract DEM (Digital Elevation Model) as a digital model of the earth’s surface elevation could be generated from remote sensing technology such stereo imaging for various applications. To generate imagery, interpolation or approximation process stage is required. Stochastic e.g. ordinary kriging uses semivariogram fitting to calculate weights values based on known points. This research applying regression types machine learning interpolate DEM. Previous conducted was LS-SVM (Least...
Most of large urban areas are historically grown around a river from small communities that eventually merge into present area. Area the river, known as watershed can be described flood water catchment basin hold overflow during rainy season. This condition is negligible at beginning when most these farmlands or undeveloped, but area developed further, with more people reside in area, this increasingly pose significant problem. Declining environmental quality Jakarta now dominant factor...
Synthetic Aperture Radar (SAR) technology is capable to provide high resolution image data of earth surfaces from a moving vehicle. This causes large volumes raw data. Many researchs were proposed about compressed radar imaging, which can reduce the sampling rate analog digital converter (ADC) on receiver and eliminate need match filter receiver. Besides advantages, there major problem that produces measurement matrix, very intensive matrix calculation. In this paper studied new approach...
High resolution images data from Terrasar-X are used to extract digital elevation model (DEM) using stereo radargrammetry in the attempt achieve better of terrain surface Indonesia. As sample this study, pairs TerraSAR-X StripMap mode (~3m resolution) on Madiun city is with difference incidence angle around ~18.88 degree area. Furthermore, field observation selected area will be accuracy assessment. The (DSM) generated by study shows us high spatial pixel spacing 5.57 meter and ~4 meter.
Abstract DEM as a model of earth’s surface plays an important role in the environmental analysis. The most common recent technology producing is SAR. Even though it has advantages compared to optical approach, generated from SAR still issues regarding process setting cross-correlation and spatial resolution determination. Both aspects will affect volume output data computational effort. This research project aimed analyze effects determination generation its accuracy. Several experiment...
The geographical position of Indonesia located between two continents and oceans is strategic, but at large risk experiencing various disasters. Climate change vulnerable location (surrounded by plates geological faults in the Earth's crust) creates an earthquake-prone region causes land/mudslides. In this paper, PS InSAR method (Persistent Scatterer Interferometric Synthetic Aperture Radar) implemented to Phased Array type L-band Radar (PALSAR) data study potential damage caused earthquake...
Within few years backward, researches had presented the ability of compressive sensing to handle large data problem on high resolution synthetic aperture radar (SAR) imaging. The main issue CS framework that should be dealt with SAR imaging is requirement linearization measurement system. This paper proposes a new approach formulating compressed echo system which derived from Maxwell’s equations continuous signal along antenna movement. Born approximation applied approximate linear form In...
Abstract Synthetic Aperture Radar (SAR) imageries data have turned out to be one of the essential sources for forest fire mapping, especially in tropical region since smoke haze obstruct acquisition by optical sensor. Despite these limitations, until now, use sensors still dominates monitoring and land fires world. The Sentinel-1 satellites presently offer unreservedly accessible freely available, world coverage fast recurrent time (6-12 days), gives images possibility broadly utilized...
Despite the fact that Sentinel-1 satellites was designed for surface deformation monitoring, researchers have been able to produce digital elevation model (DEM) using repeat-pass Interferometry. It is, however, mostly conducted in subtropical zone and temperate zone. Only a couple of publications were found tropical region. Highly dense vegetation region could cause temporal decorrelation when Interferometry is used. However, cover, as well landcover condition, still varied within this...

Peatland areas are always challenging to study; disturbed peatlands may lose their capability retain water and can get caught in burning while exposed anthropogenic activities. Less prior studies captured how wetness be physically detected 2D 3D planes, where the interactions incorporated mainly by soil moisture instruments satellite imagery. This study aims estimate peatland's level based on reflection images data analysis of ground penetration radar (GPR). The GPR instrument is frequently...
