<br>
I have populated a raster layer using a Tileindex made from ECW Files. This
layer is visible 1:1000 scale with MAXSCALE parameter.<br>
As is not possible to create ECW pyramids. Whe have got another raster layer
resampling these ECW files. <br>
We would like to populate a single raster layer that uses one tile index
created from the resampled ECW, visible at 1:10000 scale (and smaller), and another
tileindex from the original ECW files visible at bigger scales. <br>
Is it possible? If not, please tell me how could I do something similar.<br>
<br>
Tnaks.<o:p></o:p></span></font></p>
