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.

|
53 **How to use it**
|
|
|
54
|
|
|
55 Select a raster file from history and chose levels to build.
|
|
|
56
|
|
|
57 |
|
|
|

|
|
|
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.
