A region adjacency graph is constructed by representing regions as vertices and connecting these vertices that are spatially close by edges. Then, dissimilarities between neighboring vertices are computed using statistical and structural features, and are assigned as edge weights. Finally, the compound structures are detected by extracting the connected components of the graph whose edges with relatively large weights are removed. Experiments using WorldView-2 images show that grouping of these vertices according to different criteria can extract high-level compound structures that cannot be obtained using traditional techniques.","PeriodicalId":193438,"journal":{"name":"2012 IEEE International Geoscience and Remote Sensing Symposium","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126187141","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}

One RADARSAT-2 scene was acquired on February 15, 2011 and three processing chains were tested to accomplish this task. It was found that the Lee and Pottier [2, 4] method and more specifically the information imbedded in the class distribution offers a great potential. While some environments such as sea water or a city may be sorted out using a single class, the more diverse range of mechanisms involved into the backscattering processes in icefoot and peat bog areas make the class distribution a better indicator to automatically extract the icefoot.","PeriodicalId":193438,"journal":{"name":"2012 IEEE International Geoscience and Remote Sensing Symposium","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121906600","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}

It is shown, that the interference pattern is recorded by GNSS receiver on the RHCP, weakly dependent on the moisture and surface roughness of the soil. At the same time retrieved value of soil moisture has an error of the order of the measured value.

The change of glacier mass is locally depending on e.g. precipitation, melting and variation in ice flow. In this paper we analyze the data acquired by ICESat/GLAS laser altimetry, along several tracks over the glaciers of the Nyainqêntanglha range from February, 2003 to November, 2004. The surface characteristics are evaluated within laser footprints over the glacier outlines based on the glaciological inventory on the Tibetan Plateau constructed by CAREERI, CAS. For this purpose, we extract two waveform parameters: the waveform width and the number of modes. These parameters are compared with surface slope and roughness obtained from the ASTER GDEM (Global Digital Elevation Model).","PeriodicalId":193438,"journal":{"name":"2012 IEEE International Geoscience and Remote Sensing Symposium","volume":"102 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134256660","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}

In this paper, Gansu Province was selected in Northwest China to study vegetation NPP based on adjusted boreal ecosystem productivity simulator (A-BEPS) model in arid and semi-arid regions. Net primary productivity of vegetation was simulated in Gansu Province from the year of 2002 to 2010 with moderate resolution remote sensing imageries and meteorological data. And then, spatial-temporal distribution patterns of average NPP were analyzed in Gansu Province from the year of 2002 to 2010. The results show that it is high in the south and low in the north for spatial distribution, and obviously seasonal characteristics are got in Gansu Province. Finally, the trends of averaged NPP for three vegetation types and relative meteorological factors were analyzed for the past nine years. The results of a little decreasing NPP and precipitation are got for Gansu province.","PeriodicalId":193438,"journal":{"name":"2012 IEEE International Geoscience and Remote Sensing Symposium","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123451852","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}

Spatial distortion is measured at full scale according to the QNR protocol on land cover classes defined by NDVI thresholding.

The results indicate that the spectral angle cosine-Euclidean distance method demonstrates the most superior ability to distinguish various land cover types among five methods because it fully utilizes both the spectral amplitude and shape feature in the hyperspectral data. A combination of the spectral amplitude-sensitive method and the shape-sensitive method will effectively improve the identification accuracy of different land cover types.
