I have been comparing the performance of (gdal based) qgis against * ahem *
arcmap using the Nasa blue marble visible earth dataset (two tiffs totalling
roughly 2.8gig). In general arcmap rendering is faster, especially when
zoomed out so that most or all of the dataset is in view.
I found the following message in the archives:
And was wondering if the use of rrd files is automatic in the gdal tiff
driver, or if there is something special I need to "activate"?
On a similar note, if I create overviews using the gdaladdo utilitiy, does
gdal automatically look for and use the associated .ovr file?
Lastly, is it possible call gdaladdo programmatically?
The only reason for time is so that everything doesn't happen at once
