具体数据处理求教!
<P>现有一幅省矢量土壤和行政图，土壤图分>100个亚类，有更高一层的约15个土类，土壤图属性中有每个亚类的ID和面积，要求分县统计更高一层的15个土类的面积，并成图，请问如何处理？能说明步骤就更好。</P><img src="images/post/smile/dvbbs/em01.gif" /><img src="images/post/smile/dvbbs/em01.gif" /><img src="images/post/smile/dvbbs/em01.gif" /><img src="images/post/smile/dvbbs/em01.gif" /><img src="images/post/smile/dvbbs/em01.gif" /><img src="images/post/smile/dvbbs/em01.gif" /><img src="images/post/smile/dvbbs/em12.gif" /><img src="images/post/smile/dvbbs/em12.gif" /><img src="images/post/smile/dvbbs/em12.gif" /><img src="images/post/smile/dvbbs/em12.gif" /><img src="images/post/smile/dvbbs/em12.gif" /><img src="images/post/smile/dvbbs/em12.gif" />
