Hi, everybody. I create a new tiff , just named it A, from another tiff
(named B ), and set the projection by wkt which is read from the B.
But prejection of A cann't be read by arcgis 9.3, and B can . what about the
problem is?
The projection info is like this :
PROJCS["IMAGINE GeoTIFF Sup
hello, everyone.
I need to justify whether one geotiff and one shapefile are in the same
projection with IsSame function from OGR, which will compare the wkt info of
OGRSpatialReference , like below.
bool CompareWktIsUniform(const char* pszWkt1, const char* pszWkt2)
{
OGRSpatialReference S
Hello, I write some code below to compare OGRSpatialReference,
bool CompareWktIsUniform(const char* pszWkt1, const char* pszWkt2)
{
OGRSpatialReference SR1(pszWkt1);
OGRSpatialReference SR2(pszWkt2);
int IsSame = SR1.IsSame(&SR2);
if (IsSame == TRUE)
return true;
else
return false;
}
Thank you.
And what about those pvevious versions, such as from 1.6.0 to 1.6.2?___

Hi, Thank you once more.
As you said, it seems that GeoTiff and HDF also have subdatasets.
So, I wonder that is there any character which can differ HDF from other
formats?___

After Reading API doc, I find it clear that GEOS lib is necessary for spatial
analysis.
And what about Proj? Does Gdal need supports from Proj lib for Reprojection and
Transformation?

Here is my local code and result, is there something wrong?
char ** SUBDATASETS = GDALGetMetadata( (GDALDatasetH)m_pSrcDataset,
"SUBDATASETS" );
After anterior code, for GTiff dataset, it return a NULL result.
So I am puzzled that whether SUBDATASETS shared for GTiff?__
Hi, your explanation is so exhaustive, nothing better than thank you once more.
Maybe the last one question on this topic, is "SUBDATASETS" also shared by
Gtiff? ___

By generally reading the api doc, and as a freshman, I find it hard to get
exact value of those const char params and options.
Do you have a good idea?

supported formats of ogr .
The code like below, The parameter "const char" are copied from api doc. But

Hi, I'm not quite sure about what you need to analyze the problem. But I will
write down all details which I consider helpful.
I build all dlls (gdal_HDF5.dll, gdal_HDF5Image.dll), add
C:\gdal\gdal162\bld\bin as system variable.
Then I reset VS2008 as VC++ with default settings, add

Hi, I'm working with HDF4 and HDF5 using gdal in VS2008, and I get lots of
troubles which make me confused.
As all the guides said, I modified the nmake.opt like this;
MSVC_VER=1500
GDAL_HOME = "C:\GDAL\gdal-1.6.2\bld-162"
# Uncomment the following and update to enable NCSA HDF Release 4 support.
Hello, thanks for your help.
I check the release-1500-gdal-1-6-mapserver-5-4 package, and find out that
gdal_HDF5.dll and gdal_HDF5Image.dll are under the folder \bin\gdal\plugins. To
make HDF5 work well, these two dlls are essential, is it?
By the way, It seems that these two dlls are copied
I'm a freshman, and I want to support HDF5 format in my program by using gdal,
which version of lib HDF5 should be added to Gdal, 1.6.X or 1.8.x?
It seems that 1.8.x has taken great changes. And it seems that gdal recommands
1.6.x, for c:\warmerda\supportlibs\hdf5\5-164-win

Hello, I am a freshman in working with Gdal and HDF5 in Visual C++ 2008. I have

I set up a project , add include and lib to this project. Then I copy some
sample codes to test how gdal and hdf5 works.
