The textural characteristics were determined by applying a discrete wavelet transform and with use of a textural matrix, on the basis of which the following textural indices were determined: energy, standard deviation, inertia, entropy, homogeneity factor, cluster shade (asymmetry), cluster prominence, and cluster correlation information measure. An unsupervised classification of valuation tracts was made for a space image of a test area within the Bulun forested sector of the Zhigansk forest management area registered by the Landsat 7 satellite. The use of textural indices alone for classification purposes proved to be inadequate. Satisfactory results were obtained only with the joint use of both textural and brightness spectral indices.","PeriodicalId":405012,"journal":{"name":"Mapping Sciences and Remote Sensing","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132772158","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 the case of the precision oceanographic radio altimeter (PRA), irradiating the sea surface from space orbit altitudes, the reflected signal is subjected to both fast and slow fluctuations. In this paper a study is made of the dependence of the cross-correlation function of interperiod fluctuations and the correlation interval on the parameters of the PRA, irradiation conditions, and sea surface state. The results make possible correct selection of the repetition interval of the sensing signals and the necessary time of smoothing in the PRA tracking system for achieving a stipulated accuracy in measuring height.","PeriodicalId":405012,"journal":{"name":"Mapping Sciences and Remote Sensing","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131718102","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 authors demonstrate that the radiometric characteristics of water color perceived by an observer from above may experience considerable changes, depending on the nature of bottom cover (ooze, vegetation), the depths at which the bottom occurs, the geometry of water surface illumination by sunlight, and the concentrations of such substances as chlorophyll, suspended mineral matter (SMS), and dissolved organic matter.","PeriodicalId":405012,"journal":{"name":"Mapping Sciences and Remote Sensing","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130102010","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}
