However, most ground deformation monitoring mainly focus on the single city, thus it is difficult to reveal the regional extent of the deformation. Fifty-five ALOS/PALSAR images acquired from three adjacent tracks from 2007 to 2011 are used to obtain annual deformation rate based on Small Baseline Subsets (SBAS-InSAR) technique. The standard deviations of deformation differences between two adjacent tracks are 3.7mm/a and 4.2mm/a, respectively. Large subsidence funnels mainly occur in the regions, where the groundwater pumping is intensive. The maximum subsidence is observed in Qingxu with the land subsidence rate up to 240mm/a, while regions with subsidence rates ranging from 50 to 90mm/a are detected in other locations. Meanwhile, significant deformation differences are retrieved in both sides of the faults, which could be explained as the faults-controlled deformation.","PeriodicalId":179622,"journal":{"name":"2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124748440","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}

The system has been extended to retrieve variables based on the Global Precipitation Measurement Microwave Imager (GPM/GMI) instrument observed radiances. The inversion algorithm is a One-Dimensional Variational (1DVAR) scheme and is consistent across sensors and uses an iterative approach in which a solution is sought that best fits the observed satellite radiances, subject to other constraints. The Community Radiative Transfer Model (CRTM) is used as the forward and Jacobian operator to simulate the radiances at each iteration prior to fitting the measurements to within the noise level. This paper describes the MiRS retrieval algorithm, its extension to GPM/GMI, and validation against several reference data sets, including National Centers for Environmental Prediction (NCEP) Stage IV precipitation analyses, as well as with the European Centre for Medium-Range Weather Forecasts (ECMWF). Results indicate that MiRS can retrieve details of the atmospheric water vapor, hydrometeors and surface precipitation in an accurate and self-consistent manner.","PeriodicalId":179622,"journal":{"name":"2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS)","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124773030","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, there are little discussions about the selection of the sampling frequency on the undersampling condition and corresponding measuring method when the signal's frequency is too high. In order to solve the problem aforementioned, this paper proposes a modified method based on Coherent Accumulation and DFT. Firstly, the appropriate under-sampling frequency is chosen to sample the two sinusoidal signals with the same frequency. Then, the sampled signals are coherent accumulated with the period of the baseband signal. Thirdly, the accumulated sampled signals are used to calculate the initial phases of the two sinusoidal signals by using the Discrete Fourier Transformation. Lastly, the phase difference is gotten from the initial phases. Experiment results prove the effectiveness of the method.","PeriodicalId":179622,"journal":{"name":"2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129473872","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}

The goal of classification is to acquire the class label of each pixel. The land covers is linearly separable in the kernel space spanned by class labels (ideal kernel). The ideal kernel is used as the optimization objective of our proposed MKL algorithm. Linear programming (LP) and signal sparse representation (SSR) are used to find the optimal weighting coefficients of basic kernels in our proposed based on ideal kernel MKL (BoIKMKL), thus leading to two variants of the proposed method, BoIKMKL-LP and BoIKMKL-SSR, respectively. Experiments are conducted on a real hyperspectral data set, and the experimental results show that the proposed algorithms, especially for BoIKMKL-LP, achieve the outstanding performance for hyperspectral image classification with few labeled samples when compared with several state-of-the-art algorithms. To a certain extent, BoIKMKL-SSR solves the problem of basic kernels redundancy with satisfactory classification accuracy.","PeriodicalId":179622,"journal":{"name":"2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130222651","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}

When banks are overtopped, water spreads over flood plain and generally causes problem for inhabitants, crops and vegetation. During extreme flood events, it is important to determine quickly the extent of flooding and land use under water. Flood maps can be applied to develop comprehensive relief effort immediately after flooding. There are varieties of issues and uncertainties involved in flood mapping. Remotely sensed data can be used to develop flood map in an efficient and effective way. In this paper different techniques of flood mapping using active and passive remote sensing systems are applied, so that a final flood inundation map has been prepared by combining all data within a Geographical Information System (GIS) environment. The flood inundation maps can be further used for quick identification of areas of potential flood hazard to minimize the flood losses.","PeriodicalId":179622,"journal":{"name":"2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130381597","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}

Based on the parameters of land surface, the applicability of NDVI-land surface temperature (NDVI-LST) and NDVI-albedo triangular methods were validated using the landsat7 data and the Heihe Watershed Allied Telemetry Experimental Research (HiWATER) observed data. Considering the affecting of soil moisture and vegetation water content on ET, a modified triangular method was developed using the Perpendicular Drought Index (PDI). Compared the estimated ET to the observed value, the result showed that LSTs retrieved by single channel method were closed to the measured data, and the correlation coefficient(R) was 0.8, the root mean square error (RMSE) was 5.72K and the mean absolute percent error (MAPE) was about 14.48%. The correlation coefficient between the PDI, soil moisture and vegetation water content was 0.77, so the PDI could respond the moisture condition of the surface well and could be used to estimate the ET. The ET estimated by NDVI-LST and NDVI-albedo triangular methods were in good agreement with those measured values and the correlation coefficients were 0.85 and 0.86, respectively. The NDVI and PDI showed a triangle relationship obviously, and the accuracy of estimated ET from NDVI-PDI triangular method had improved greatly, the RMSE reduced to 91.72 W·m-2 and the MAPE was 24.84%.","PeriodicalId":179622,"journal":{"name":"2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130512730","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}
