This doesn't help with gdal_contour of course, but is a viable way of doing
the same thing. Maybe worth considering as a new python tool.

Hi Sam,
If your gdal build has Rasterlite support, you can use that to store
multiple rasters at their native resolution. For each raster do something
like this, where table is a unique name for each raster. I used the file
name for table, but it can be anything.
gdal_translate -of Rasterlite
I would use the CENTER_LONG config argument. That will extend the raster
past the -180/180 boundary depending on which side you want to extend.
--config CENTER_LONG 180
Upper Left ( 176.0010322, -16.1523859) (176d 0' 3.72E, 16d 9' 8.59S)
Lower Left ( 176.0010322, -18.2685614) (176d 0' 3.72E,
You could run gdal_polygonize on the mask geotiff and then use the output
vector with gdal_rasterize. That's the only way I can think of without
writing a python script to do the pixel comparisons.

Hello all,
Question - is there some reason why gdal_translate needs to show a format
listing when invoked on the command line with no arguments? On my system
this outputs 61 lines which is nearly a maximized shell on my 24 monitor.
Wouldn't requiring the --formats flag be more consistent with

to get nodata values to show up as transparent in the output. Are there
format specific creation options I should be using?

I quickly ran this in a python shell:
from osgeo import osr
wkt =
'GEOGCS[GCS_ITRF_2000,DATUM[D_ITRF_2000,SPHEROID[GRS_1980,6378137.0,298.257222101]],PRIMEM[Greenwich,0.0],UNIT[Degree,0.0174532925199433]]'
srs = osr.SpatialReference()
srs.ImportFromWkt(wkt)
srs.ExportToProj4()
I've written some simple Python code to flip a raster in relation to the
y-axis. The raster is 2x19459 and has 4 bands of type Byte, and is
written east to west (I have no idea why). The script proceeds normally for
the first 2 bands, but slows way down after starting band 3. I let it run
, inband.XSize, 1)
flipline = numpy.fliplr(inline)
outband.WriteArray(flipline, 0, i)
inline = None
inband = None
outband = None

There is no UTM zone specified in the input proj string. Is that the issue?

Hello all,
Is there a way to get the 1.6 version of gdal2tiles to clamp tiles to the
seafloor? I've tried modifying the script with altitudeMode
gx:altitudeMode, but the tiles remain clamped to z=0. What's the correct
approach?

I had a similar issue with gdal gtiff output awhile back and solved it by
using the internal gdal libtiff. Try using --with-libtiff=internal when
compiling gdal.

That would likely explain the shift - the documentation probably hasn't been

Hey Michael,
Have you tried EPSG 102684? There's a esri_extra file in the FWTools/share
dir that has additional definitions, including Maine Stateplane West Nad83
