described methods to do this. But I have a few (quick) questions. Thanks for
your help</p>

<p class="MsoNormal" style="margin-bottom:6.0pt;line-height:normal"> <span class="Apple-style-span" style="font-family: 'Trebuchet MS', sans-serif; font-size: 13px; ">Question 1: can
those methods be applied using a GRASS Script? (I believe so)</span></p>
<p class="MsoNormal" style="margin-bottom:6.0pt;line-height:normal"><span style="font-size:10.0pt;font-family:"Trebuchet MS","sans-serif"">Question 2: in
method 1 (</span><a href="http://grass.osgeo.org/wiki/MODIS#Method_1">http://grass.osgeo.org/wiki/MODIS#Method_1</a>),
It’s said to create a Project/mapset with EPSG 3266. Why that system? And Why if
gdal_translate will create geotiff in EPSG4326?</p>
<p class="MsoNormal" style="margin-bottom:6.0pt;line-height:normal">Question 3: Regarding
a_ullr. This flag asks for Upperleft and lowerright. This means that those
values are the same for all files. But in the case that they may vary. How can
I obtain them from MODIS Metadata/header? And this would mean that the we are
dealing with a regular dataset because in a Geostationary dataset this wouldn’t
be possible (I guess).</p>
<p class="MsoNormal" style="margin-bottom:6.0pt;line-height:normal">Question 4:
What is the –co flag? I read Gdal_translate description but I didn’t find it
very clear..<span style="font-size:10.0pt;font-family:"Trebuchet MS","sans-serif""></span></p>
<p class="MsoNormal" style="margin-bottom:6.0pt;line-height:normal"><span style="font-size:10.0pt;font-family:"Trebuchet MS","sans-serif"">Question 5: As
far as I can see, Geotiff format is used as an intermediate format in order to import
data to GRASS. Why is it chosen?</span></p>

a list of the formats that GDAL automatically georreference?</span></span></p>

not being used right?</span></span></p>
