I am working with a single band raster of 10mX10m cells. I have added overlays with gdaladdo and it displays nicely.
When I query the layer I am using MODE=nquery, not MODE=query. The reason that I am using nquery is unrelated to the raster layer, but I'm pretty much restricted to using that mode. At large scales this returns at least 2 cells, which I can average easily with JavaScript in the browser. However at small scales I'm getting 10s of 1000s of cells which are really slowing things down. It does not appear that query or nquery mode is using the overlays. Anyone disagree with that assumption? So the only solution that I've come up with thus far is to resample the raster to larger cell sizes and use the min/max scale denominator to select a layer with cell size appropriate to the scale. Anybody have other ideas?
