Evaluation of Various Satellite Sensors for Quantitative Retrieval of Different Elements in Diverse Power Plant
摘要
Abstract
[Objective]The impacts of spatiotemporal resolution of remote sensing satellite sen-sors were explored on the accuracy of quantitative retrieval of different elements in diverse re-gions.[Methods]An ability of various satellite sensors for waterline extraction and inundated area identification was evaluated in Shouguang coal-fired power plant and the northwest typical flood area.[Results]The result of shoreline change monitoring shows that tidal variations and terrain change can affect the use of remote sensing techniques for delineating coastline.In dif-ferent beach slope scales,waterline heightens error,interpolation inaccuracy,inadequate sensor resolution and slope correcting error will sepa-rately play a maj or role.In the extraction of flood inundated area by remote sensing inver-sion,the soil moisture content method using Landsat data is considered more accurate in ex-tracting of flood-mark and inundated area based on the comparative verification of the results of the field survey and simulation.[Conclusion]This study can provide reasonable remote sensing data source and the corresponding technical methods for the location selection and post monito-ring of power plant,and also service the reliable theory basis of remote sensing interpretation on the environmental monitoring of engineering site.关键词
