[GRASS-user] Global Land Cover Characterization data type

[Michael Spencer]

Have added a page to the wiki:
http://grasswiki.osgeo.org/wiki/Global_Land_Cover_Characteristics

Also linked to it from here (and tidied imagery into abc...):
http://grasswiki.osgeo.org/wiki/Global_datasets

Remarkably painless!

Got the job done, thanks for all the pointers.

Took location info from the readme file included in download (which is different to the online help). Used a lat-long on wgs84 projection.

Imported via r.in.bin, and again included the details from readme file in bounds tab.


Strikes me usgs made this a lot more difficult that it needed to be!

Maybe worth to be put in the wiki, could you be so kind?
Thank you!

Thanks again,

Hi Michael,

http://edc2.usgs.gov/glcc/globdoc2_0.php#dataform
says that data is in binary flat format, no header...
I suppose that if you download in geographical lat long projection, and that you get the header info from:http://edc2.usgs.gov/glcc/globdoc2_0.php#geog



then you should be able to set a new location from this info and import straight in GRASS with one of the generic binary input function (maybe in r.in.gdal, maybe another more specific.

good luck and tell us how it went,Yann

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
