size weight illusion

Shape weight is the weight index reflecting varied trunk shape and the direct conversion factor of trunk weight too.

形重是反映不同形状树干的重量指标，同时又是树干重量的直接换算因子。

A terrain reconstruction algorithm of DEM datum is proposed based on bi-cubic B-spline interpolation according to attention difference of terrain area,and using the multi-resolution terrain model can lighten computer load,process terrain reconstruction to attention area,and improve the resolving power.

采用该算法可以有效地对关注度较高的区域进行地形重构,提高该区域的地形分辨率。
