Hi ,
My user asked me to give him some description of the algorithm of gdal
contour generator as detailed as possible. I have poor theory about this
problem, anyone could tell me some workflow of this module to save time when i
browse the source code? Thanks.
HI !
i am new in the use of GDAL and i want to merge several jpg-files (100
images) of a folder in to on - optional by reduce the resolution.
my problem is that i only found the command gdal_merge - but not the
right options.
can anybody tell me a link or a good example.
regards Jan :-)
Hi Jan,

Hello All,
I made a shapefile from a raster layer using gdal_polygonize.py. My
input values are float, but my first attempt of gdal_poligonize.py has
truncated these to integer values.
Ok, so I read the description of the utility on
http://www.gdal.org/gdal_polygonize.html, which says:
Hi all,
I need a way to retrieve a GDAL DataType (its code or its string name,
it's the same) starting from all information on it. Does it exist a
class or method to to this?
For example:
GdalDataType(nbits=32, float=True, Complex=True) - gdal.GDT_CFloat32
I use Python bindings for GDAL.
I'd like
Hello,
I've a problem with gdal2tiles. I need to create tiles from an image
of 5 GB, more or less. The image has been created rasterizing a
shapefile. The shapefile's original projection was epsg:23028, but I
had to reproject it to epsg:23030 (because I had to cross this
shapefile with other ones

I just noticed that when setting GDAL_DRIVER_PATH in the environment,
it overrides the paths configured into GDAL, instead of adding to
those paths. Was this intentional? Any way to tell GDAL to *add*
GDAL_DRIVER_PATH to the configured paths?

You could easily roll your own.
from osgeo import gdal
class GdalDataType(object):
def __init__(self, nbits, Float, Complex):
for i in range(0,gdal.GDT_TypeCount):
self.DataType=None
DataType=i
DataTypeName=gdal.GetDataTypeName(i)
Ooops... I neglected the signed check.
