[Qgis-user] Convert an Ascii raster to Image

[Lene Fischer]

Dear Zoltan,

No. 2 was best for me. Now it is 20 mB and OK 
No 1.  Gave a filesize 1.2 Gb - I had already tried that solution.

Thanks

Regards
Lene

Dear Lene,

1st solution
Open ASCII GRID as a raster layer and in the context menu of the layer select Save as...

2nd solution
>From the Raster menu select Conversion -> Translate (Convert format), select input and output raster and format.

This way you get a single band raster which is not the most beautiful as a background layer. You had better to make a color relief (Raster menu -> Analysis -> DEM) and a hillshade. Use blending of the color relief and hillshade to get a nice terrain background in QGIS 2.

Regards,
Zoltan
