[Qgis-user] Raster file format

[Nicolas Cadieux]

Hi,

I will be making huge... (No HUGE) DEMs file in QGIS.  I usually use .tif or.tiff (not really sure what the real difference is) but they are large files.

What would be the best Qgis raster format permitting both smaller disk storage, lossless compression and ease of analysis using the various Qgis plugins? Formats need to accept floats.  I only use one band.

Thanks for the help.
