Hi,
Im trying to import the USGS Global Land Cover Characterization
dataset (http://edc2.usgs.gov/glcc/globe_int.php). Ive tried to create
a header as described below but am having no luck. Im not too sure how
to append the header information to the img file. I was wondering if
anyone had already done this?
Thanks,
Darren

Hi,
Has anyone used the USGS Global Land Cover Characterization data available
here?
http://edc2.usgs.gov/glcc/globe_int.php
Indication is that the file format is Erdas Imagine .img, but GRASS is
coming back with a file type unknown error. Help/readme file suggests data
is byte type, which leaves me none the wiser!
Happy for any pointers.
Ta,
Michael
Hi Michael,
Some time ago I had the same problem when using R for reading the
files. From the USGS I was told that the problem is the lack of header
(as mentioned in the metadata that I did not read :( )
You need to make a projection header file as per the FAQ at:
http://landcover.usgs.gov/faq.php#three
The details of the LAEA projection to generate the header file can be
found on:
http://edc2.usgs.gov/glcc/sadoc2_0.php
IHTH,
Mauricio
