47 **What it does**
48
49 The gdaladdo utility can be used to build or rebuild overview images for most supported file formats with one of several downsampling algorithms.

52
53 **How to use it**
54
55 Select a raster file from history and chose levels to build.

58
59 **Option**
60
61 *-levels*
62
63 A list of integral overview levels to build. Ignored with -clean option. Starting with GDAL 2.3, levels are no longer required to build overviews. In which case, appropriate overview power-of-two factors will be selected until the smallest overview is smaller than the value of the -minsize switch.
