Hi,
When you use RasterIO
(http://www.gdal.org/classGDALDataset.html#ae077c53268d2272eebed10b891a05743)
GDAL automatically switch to right overview based on input parameters. I
think ArcGIS do it the same way.
Regards,
Dmitry

Iam beginner to GDAL.
I have an Image which has internal overviews in it. I am able to display
each overview separately, but i want to dynamically select the corresponding
overview when that image is zoomed in/out. Which method i need to use in
GDAL to achieve this functionality. And how does ArcEditor 10 understand
which overview to display.
