[GRASS-user] Importing .img file

GRASS GRASS user
,

   I have a set of files that appear to be ESRI raster image files:

Metro_Highres_value_definitions.xlsx
metro_highres.img.xml
metro_highres.img
metro_highres.lpk

and I've not before seen this type of data.

   Looking at the image commands I don't see one appropriate for importing
these data; perhaps r.in.gdal would be appropriate? The provided .xml file
is attached.

   Please provide advice on importing these data.

TIA,

Rich

A quick google of ‘gdal supported formats’ gives:

I suggest you have a read. My guess is r.in.gdal would work on your .img file. Have you even tried it?

Hi

As far as I know, .img is ERDAS Imagine raster format.

You should be able to open it with r.in.gdal, as GDAL can both read and write it:

James,

   Mea culpa! I should have run ogrinfo --formats before writing.

Thanks,

Rich

Hernan,

   That looks familiar from many years ago.

   I now see that 'gdalinfo --formats | grep .img' has support for it here:

$ gdalinfo --formats | grep .img
   HFA -raster- (rw+v): Erdas Imagine Images (.img)

Thanks,

Rich
