Convert from img to geotiff

Question

Using gdal translate, would it be possible to convert from IMG to GeoTIFF?

We have very little experience with gdal.

Answer 1

gdal_translate -of GTiff  C:\temp\input\a.img   C:\temp\output\a.tif

and the batch option

GDAL_translate: converting ESRI GRID to Geotiff in batch

'-of GTiff' this part is probably not even required as this is the default but will do no harm.

Answer 2

As part of their NED data delivery changes in 2013, the National Map provided a set of file conversion scripts. See this script:

GDAL_IMG_2_GeoTIFF.bat c:\temp\input.img

The result is dropped in a sub-directory:

IMG_Output\GDAL_IMG_2_GeoTIFF.tif

For converting many files, you may consider this script

GDAL_Convert_All_IMG_2_GeoTIFF.bat

Recursively Scans directory for IMG files and runs GDAL_IMG_2_GeoTIFF on all

The GeoTIFF will be put in the same directory as the IMG file.

At the time of writing, the scripts are available as a zip file at this link.
