I assume it is the same to determine the latitude zone (using 8
degrees). The one thing though are the exceptions (even though I don't

Hi,
if i want to convert from lat/lon to UTM (both based on WGS84). Do i
have to know the UTM zone a priori? If so, why?
Can anyone provide some insight on this? I'd greatly appreciate it.
thanks

Hi,
I have a satellite scene specified in geographic coordinates (i.e.
WSG84, lat/lon). For the purpose of interpolating onto a
distance-regular grid i want to transform that data to a projected
systems (UTM). I am using gdal in python. To go from projected to
geographic (the inverse of i what i wa
could not find it.

Nevermind, i got confused. Downloaded the wrong code.
Sorry about that.

Hi,
i would like be able to make use of GDALGridCreate() in my python code.
Since it has not been mapped to python i'd like to do that myself. I
don't have experience with this though, so i am looking for some
direction on how to get started. I read up a little on it and i think i
understand the ge
rated, but when i try to open it, but i cannot open
it and the file is somehow corrupted. For the experts on this utility,
am i doing something obviously wrong?
thanks

Hi,
i have several satellite scenes which basically give me 3 vectors:
lat/lon/data which is on an irregular. I would like to interpolate those
onto a regular grid. I found that GDALGridCreate would meet my need
except that i am developing in python, but it appears the bindings for
it don't exist (
Yup,
that was it. I should have looked a little closer i suppose ...
thanks

Hi,
i am using python/gdal. I am trying to open a MODIS satellite file from
the Terra satellite (which is hdf4-eos format). Doing:
ds = gdal.Open(file)
drivertype=ds.GetDriver().LongName
returns

Hi,
i am fairly new to the earth science field and its implementation in
terms of programming.
I had a question that is probably fairly obvious to most:
What is the difference/relationship between gdal and opengrads (or does
there even exist such a relationship?). Is one build on top of the
other.

Anyway, maybe this is not a gdal issue after all.

Hi,
i am somewhat new to gdal and the grib format.
I need to read in a grib2 file which contains latitude longitude and
elevation.
So i do:
ds = gdal.Open(filename)
and
print "ds.GetRasterCount(): %s" % ds.GetRasterCount()
gives: 1
I can proceed to read in this band, but all the data that i get i
Hi,
i am a bit new to the gdal library. I am trying to process some geotiff
files in python.
1) I am making a call to the ReadAsArray data as such:
...
band = ds.GetRasterBand(1)
array = band.ReadAsArray(0,0,band.XSize,band.YSize)
print array.shape
...
which returns: (7191, 8331)
Now, what i don'
20 matches
