地学分析在遥感专题制图中的应用

为了提高数字图像制图的质量和精度, 许多研究人员部在从不同途径探索各种有效方法。本文从地学角度出发, 以地学知识和理论为基础, 结合遥感专题制图, 对成图信息源和数字图像识别的区域参数, 作了综合分析研究。本文重点讨论数字图像冬小麦的识别制图, 用地学、生物学知识和理论, 分析冬小麦等农作物的物候规律, 研究其分类识别的最佳时相图像; 另外, 结合盐碱土等地物的模式识别制图进行了区域参数的分析、确定和量化研究。

APPLICATION OF GEOGRAPHIC ANALYSIS TO REMOTE SENSING THEMATIC MAPPING

Abstract To improve the quality and accuracy of digital image mapping,different methods are under exploration. This paper analyses and studies regional parameters of information sources mapped and digital image recognition pattern combined with remote sensing thematic mapping on the base of geographic knowledge and theory from pointview of geography.The paper,based on digital image mapping objectives.analyses and investigates the phenological data and optimization temporal image of wheat according to geographic aod biochemistic theories in digital image recognition mapping.Meanwhile,analysis,determination and quantitation of regional parameters are also carried out combined with alkali-saline soil recognition mapping
