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, 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 intuitive, 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 reduced-resolution mosaic image, and as the user zooms
in, seamlessly displays 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.
