Raster layers added to ArcScene are auto resampled "on the fly" for better performance initially, which is nothing but a layer property...NOT the source cell size of the layer. The "underlying" raster props (cell size, extent, etc) can be checked through layer properties -> source tab. <BR><BR>Check the ArcScene raster layer properties, Base Heights tab, Under the Height option where the source layer is setting the height for the scene, click the raster resolution button...you can set it to the original cell size of the raster surface. <BR><BR>Make sure you do that for other layers draped on that surface as well....becareful, full sampling or smaller resampling requires more hardware capabilities, graphics memory, RAM, texture memory, etc.

<P> 按照Gis先生的意思，不能用程序实现改变raster quanlity ,这里raster是制作好的Spot5 遥感图，Spot5遥感图在Erdas 里看3维效果比较好，因为要做成程序，所以借助ArcScene，如果让Spot5遥感图遥感图效果更好，必须改变raster quanlity ，</P>
