Hi,
when trying to export LatLong SPOT VGT satellite data with
the following cellhd file:
proj: 3
zone: 0
north: 75:00:16.071429N
south: 56:00:16.069919S
east: 179:59:43.924424E
west: 179:59:43.928571E
cols: 40320
rows: 14673
e-w resol: 0:00:32.142857
n-s resol: 0:00:32.142857
format: 0
compressed: 1
I get:
r.out.tiff -t 0001_NDV out=test
D0/0: N:75.004464 S:-56.004464
D0/0: W:179.995536 E:539.995535
the W/E values confuse QGIS or other GIS software
later (also me).
It seems that G__read_Cell_head() doesn't handle the
wrap around as needed.
The map position looks almost ok (precision issue?), I have
overlayed VMAP0 vector data.
How and where to fix that?
Markus

CARTO_UPPER_RIGHT_Y 75.000000
CARTO_LOWER_RIGHT_X 179.991071
CARTO_LOWER_RIGHT_Y -56.000000
CARTO_LOWER_LEFT_X -180.000000
