A couple weeks ago I was working with Dan Dye on a project using GDAL. Dan wondered why I wasn’t working with virtual formats rather than at the time GeoTIFF. With Dan’s prodding, I quickly got up to speed on using VRT and fell in love.
If VRT with GDAL/OGR is news to you, head on over to Paolo Corti’s blog and read up on the power of GDAL virtual formats.
Freaking Sweet!
