Hello,

I am working with multiple raster data sets in diverse resolutions, which presents a problem.  For example, I cannot easily overlay a 1 meter-resolution USGS quad on a 30 meter-resolution DEM.  To get all the data out of the quad I have to oversample the DEM 900 times by setting the project resolution to 1m.

It seems to me that implementing support for multiple resolutions at once would be a gargantuan pain for the poor programmers, but this is (imho) a serious limitation of the program.  Is there a workaround that doesn't involve choking my RAM with oversampled data?  Is there perhaps a workaround in NVIZ?

Thanks,
