您好,坡度计算是对具有高程数值的栅格数据集进行的,java组件中的CalculationTerrain 地形计算类,其中calculateAspect()计算坡向,并返回坡向栅格数据集,即坡向图,参考http://support.supermap.com.cn/DataWarehouse/WebDocHelp/iObjectsJava/ProgrammingReference/com/supermap/analyst/spatialanalyst/CalculationTerrain.html#calculateAspect(com.supermap.data.DatasetGrid,%20com.supermap.data.Datasource,%20java.lang.String)
calculateSlope()计算坡度,并返回坡度栅格数据集,即坡度图,参考http://support.supermap.com.cn/DataWarehouse/WebDocHelp/iObjectsJava/ProgrammingReference/com/supermap/analyst/spatialanalyst/CalculationTerrain.html#calculateSlope(com.supermap.data.DatasetGrid,%20com.supermap.analyst.spatialanalyst.SlopeType,%20double,%20com.supermap.data.Datasource,%20java.lang.String)
