For government in many countries whose peoples consumes rice as its staple food, food self-sufficiency initiatives highly depend on accurate prediction of paddy field map. Mapping paddy field task is a challenging problem which cannot be handled manually especially when the paddy fields are spread out in very wide geographical areas such as those in Indonesia. Fortunately, wide availability of satellite imagery and the advent of deep learning technology in the past ten years have made it possible to improve efficiency of most parts of those manual works involving image semantic segmentation tasks. However, satellite image-based semantic segmentation is a challenging task. High object complexity, cloud partial occlusion, larger image size than a computer memory can stored can hinder accuracy of the image segmentation results. This paper presents a method for paddy field map generating using semantic image segmentation approach in which Pyramid Scene Parsing Net model is used for segmenting satellite imagery. The generated paddy map can be used as a basis for decision-making, especially in the agricultural sector. Analysis of local land use/land cover dynamics. The results of his experiments using SPOT 6 satellite imagery from the Pahung region of Central Kalimantan achieved average training accuracy, best training accuracy and test accuracy of 0.85, 0.86 and 0.89 respectively. These results indicated that the semantic segmentation model is suitable for addressing the same task in different crops.","PeriodicalId":370213,"journal":{"name":"2022 IEEE Asia-Pacific Conference on Geoscience, Electronics and Remote Sensing Technology (AGERS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128987081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is due to the presence of a subduction zone in the west and the Sumatra fault which is parallel to each other. Such geological condition can lead to disasters (e.g earthquakes and tsunamis) whenever it occurs. Accordingly, monitoring ground deformation is an important analysis to do in this area. LiCSBAS becomes an effective open-source tool for observing time-series of ground deformation using InSAR. One of the stages, the loop closure phase is a critical step in generating the number of interferograms and pixels that will be used. The objective of this study is to observe ground deformation in Southern Sumatra by taking the optimal value of the loop closure threshold. The data processing results that the threshold value used is 1.6 rad. Meanwhile, the deformation pattern is generally divided into two areas, the western and eastern parts of Southern Sumatra. The western part close to the Sumatra Fault Zone shows a subsidence at a rate ∼115 mm/year and the eastern indicates an uplift ∼68 mm/year.","PeriodicalId":370213,"journal":{"name":"2022 IEEE Asia-Pacific Conference on Geoscience, Electronics and Remote Sensing Technology (AGERS)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134155574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it varies between species. Therefore, it is substantial to upscale mangrove explorations and studies to the species level. This study aims to perform a spectral-library-based linear spectral unmixing (LSU) analysis technique on Landsat 9 OLI-2 imagery as an alternative to the conventional mangrove species mapping methods. We used the center wavelength of Landsat 9 OLI-2's B2, B3, B4, and B5 bands to define the spectra of Sonneratia alba, Rhizophora apiculata, and Avicennia marina. We performed the LSU analysis on the Muaragembong mangrove forest area, Bekasi, West Java, Indonesia as the area of interest. The result showed that the mangrove species has a unique spectral signature. The reflectance is slightly higher at around 500–600 nm and lower at 750–770 nm than the typical vegetation spectral signature. Most of Muaragembong is covered with R. apiculata and A. marina. However, there is a distinctive spatial distribution pattern for each species. Based on the RMSE result, the model can produce a ±0.3% error in each pixel. Empirical evidence from the ground truthing helped to validate the distribution pattern. It is associated with environmental factors, such as supporting substrate and water access. This paper concludes that it is possible to perform the LSU analysis using multispectral satellite data for a large-extent mangrove species mapping. However, it is mandatory to validate the result on a ground-truthing process.","PeriodicalId":370213,"journal":{"name":"2022 IEEE Asia-Pacific Conference on Geoscience, Electronics and Remote Sensing Technology (AGERS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121182839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, a spatiotemporal analysis was carried out on SO2 concentrations due to volcanic eruptions in Indonesia in the 2019-2022 period through Sentinel-5P image data with the help of a cloud-based application, Earth Engine. Analysis was carried out at pre-eruption, during an eruption, and post-eruption to determine the difference. This analysis is performed over a weekly time frame. From the results obtained, the concentration of SO2 in the eruption area increased during the eruption and tended to be high compared to the concentration during pre and post-disaster. The distribution of sulfur dioxide is influenced by wind direction and speed, so the sulfur concentration is not always high near the area around the eruption. The value of SO2 concentration in the volcanic eruption area ranges from 0.00-0.007 mol/m2. Based on the correlation test with BMKG environmental data, the surface temperature parameter is known to be positively correlated with the SO2 value and has a negative correlation with humidity. The data that has been validated is then displayed on the website with a simple and easy-to-understand interface for users.","PeriodicalId":370213,"journal":{"name":"2022 IEEE Asia-Pacific Conference on Geoscience, Electronics and Remote Sensing Technology (AGERS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124764339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unmanned Autonomous Vehicle (UAVs) is one of the technologies that have been utilized in the agricultural sector to improve production quality and quantity. Although some advanced technology has been used, currently there are some challenges that remain to be solved to implement multi-UAV in the real environment. Some of these challenges include battery limitations in UAV and the long duration to queue at the charging station. To address this issue, a previous study has proposed Cloud Based Drone Navigation (CBDN) algorithm that can be employed to optimize multi-UAV coordination by selecting the best flight path for the UAV to reach a charging station. Such an approach has resulted in reducing the waiting time of UAVs to be charged. However, the algorithm has not considered swarm robot parameters. This study aims to analyze the use of CBDN algorithm with parameters derived from swarm robots. The performance of the CBDN algorithm will then be evaluated and compared to the Shortest Flight Time (SFT) and Individual Reservation Navigation System (IRN) algorithms as two benchmark algorithms, in terms of the total travel time. By considering real swarm robot parameters, the CBDN algorithm has resulted in an average total travel time of 17.44% less than the average total travel time of SFT and 17.25% less than the average total travel time of IRN.","PeriodicalId":370213,"journal":{"name":"2022 IEEE Asia-Pacific Conference on Geoscience, Electronics and Remote Sensing Technology (AGERS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115452695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
