The narrow shape of canal greatly limits the application of moderate-resolution remote sensing technologies. Based on newly available Sentinel-2 Multispectral Instrument (MSI) imagery with frequent revisit and higher spatial resolution, we identified variation of water/bank boundary by Roberts, Sobel, Prewitt, Laplacian of Gaussian and Canny 5 edge detectors and furtherly compared the water width results with estimation by ground measurement. The preliminary results show that all detectors can successfully monitor seasonal variation of canal water surface. Canny detector is most stable among 5 methods for time series monitoring, although overestimated the water width during dry period. Our methods and results reveal the great potential of Sentinel-2 imagery for canal water utilization and irrigation management.","PeriodicalId":13262,"journal":{"name":"IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium","volume":"65 1","pages":"4423-4426"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72578508","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, cloud and cloud shadow contamination reduce the availability of optical data, especially in tropical regions. Accurate identification of cloud and cloud shadow is an essential step in optical image preprocessing. The Function of Mask (FMASK) [1] is one of the most widely used cloud and cloud shadow detection methods. In view of the problems of some thin clouds and cloud shadows omission errors in tropical regions of FMASK, we develop an improved FMASK algorithm in tropical regions from the following two aspects: (1) Cloud detection: Firstly, the parameters and thresholds of FMASK are adjusted to generate the basic cloud layer; Secondly, the cloud index layer is calculated based on the bright features of clouds; Then, combining the temporal randomness and spectral characteristics of cloud, other bright objects are excluded and thin clouds are retained. (2) Cloud shadow detection: Firstly, the dark features of cloud shadows are mainly used to detect the basic cloud shadow layer; Secondly, combining the spectral and randomness characteristics of cloud shadow to avoid the interference of other dark objects. We randomly selected three experimental areas in tropical regions to verify the proposed algorithm developed in this paper. Through comparing and evaluating the accuracy of the clouds and cloud shadows mask generated based on the method in this paper with real samples drawn manually, the experiment results show that the average overall precision of clouds and cloud shadows mask generated based on the algorithm in this paper exceeding 80%. This improved FMASK algorithm improves the accuracy of clouds and cloud shadows detection in several tropical regions for Landsat images.","PeriodicalId":13262,"journal":{"name":"IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium","volume":"45 1","pages":"1562-1565"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78746527","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}

While methods such as neural networks are trained by online or batch processing, i.e. keeping only parts of the data in the memory, other methods such as Random Forests require offline processing, i.e. keeping all data in the memory of the computer. The latter are therefore often trained on a small subset of a larger data set that is hoped to be representative instead of exploiting the information contained in all samples. This paper shows that Random Forests can be trained by batch processing too making their application to large data sets feasible without further constraints. The benefits of this training scheme are illustrated for the use case of land-use classification from PolSAR imagery.","PeriodicalId":13262,"journal":{"name":"IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium","volume":"15 1","pages":"5808-5811"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75928384","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}

Sea level change is one of the main threats to coastal areas. Improving its observation is essential to better understand and predict the behaviour of the coastal ocean. Altimetry provides a unique set of long-term measurements to characterize the evolution of sea level variability from the open to the coastal ocean.The X-TRACK processing chain has been developed in order to recover as much altimetry data as possible in coastal areas. X-TRACK has now become a multi-mission altimetry product covering all the coastal oceans. It is produced by the CTOH (Center of Topography of the Ocean and the Hydrosphere). Recently, the Level 2 ALES (Adaptive Leading Edge Subwaveform) retracked product has been included in X-TRACK, as well as the best altimetric corrections available, thus merging the most recent advances in coastal altimetry into in a new high resolution (20 Hz ~ 350 m Level 3 alongtrack product made available for the research community.","PeriodicalId":13262,"journal":{"name":"IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium","volume":"36 1","pages":"8271-8274"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76007205","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}
