<p style="margin-bottom: 0cm" lang="en-US"><small>I have an annoying
problem
with the projection of an land cover map. I downloaded the USGS

<p style="margin-bottom: 0cm" lang="en-US"><small>the cover is an
.img file;
however, it is impossible to open it with qgis and even arcgis.
In a
website I found a guide to open this file. First I change the

<p style="margin-bottom: 0cm" lang="en-US"><small>My problem is that
I can't
change the projection to geographic coordinates/WGS84. This
happened
with all covers in this webpage. I am working in qgis 1.8
in ubuntu 12.04.
