解决办法,使用reclassify工具对栅格影像进行重分类,然后再进行栅格转面操作即可。 栅格数据重分类
在ArcToolbox工具箱中选择Conversion Tools—>From Raster—> Raster To Polygon工具,输入全水域集水流域栅格数据WatershedAll,字段选择Value,输出全水域集水流域面要素WatershedAllPol。5.4 提取集水流域内汇流量大于2 km^{2} 河网 每个栅格单元的面积是30*30 m^{2} ,提取汇流量大于2km^{2} 的河网,即汇流量>...
Raster Dataset Cell assignment type (Optional) The method to determine how the cell will be assigned a value when more than one feature falls within a cell. Cell center—The polygon that overlaps the center of the cell yields the attribute to assign to the cell. Maximum area—The single fea...

If a field is not specified, the cell values of the input raster (the VALUE field) will become a column with the heading Gridcode in the attribute table of the output feature class. The following graphic illustrates how the input raster is vectorized when it is converted to a polygon ...
