From Greg Coats:

For the Charleston, South Carolina urban area, I have quantity=1360,  
0.60 meter resolution georeferenced GeoJP2 images.  I have created  
several reduced-resolution mosaic images, that in effect form a 25 GB  
image pyramid.  When zoomed out, for any particular scale, it is only  
necessary to draw pixels from one (not all) of the reduced resolution  
mosaic images.  I have built an ESRI ArcGIS interface that provides  
for easy seamless panning, and zooming in, and out through all of  
these images.

I would like to have prepared a functionally similar, easy to use,  
QGIS project file that would access, based on the current scale, the  
appropriate mosaic image, and as the user zooms in, seamlessly  
display the appropriate GeoJP2 image.  The GDAL utility gdalbuildvrt  
would be used to define the boundaries of the 1360, full resolution  
images.  I am seeking to pay someone to develop the QGIS project  
file.  If you are interested, then please contact me.
