It looks like the extent goes slightly beyond +180 deg E and -180
deg W:<br>
<br>
micha@MS-Rebecca ~/Downloads $ gdalinfo EstISA_final.tif <br>
.....<br>
Corner Coordinates:<br>
Upper Left (-180.0041667, 75.0041667) (180d 0'15.00"W, 75d
0'15.00"N)<br>
Lower Left (-180.0041667, -65.0041107) (180d 0'15.00"W, 65d
0'14.80"S)<br>
Upper Right ( 180.0040227, 75.0041667) (180d 0'14.48"E, 75d
0'15.00"N)<br>
Lower Right ( 180.0040227, -65.0041107) (180d 0'14.48"E, 65d
0'14.80"S)<br>
....<br>
<br>
Here's what worked for me:<br>
gdalwarp -te -180 -65 180 75 -tr 0.0083 0.0083 EstISA_final.tif
estisa_fixed.tif<br>
<br>
Then I imported the fixed raster, and it displayed OK. This will
shave off a few pixels around the edges. But I don't think there's
any way to avoid that.<br>

<div>Using GRASS 7.0 on Ubuntu I'm actually able to import the
file without errors, but it will not display. On my Mac I
can easily display the image in Preview and I can drop the
file into QGIS 2.4 and it also displays fine.</div>

<div>I have tried many different options importing the GeoTiff
file, but it just will not display. If I use <a
moz-do-not-send="true" href="http://r.info">r.info</a> the
E-W and N-S bounds are correct and the N-S resolution looks
right (0:00:30 deg), but the E-W resolution is very small
(0:00:00.000335 deg); also…</div>
