[gdal-dev] gdal dataset
Hi All, I have generated gdal , ogr , osr dlls and added them to my c# project. Now i am trying to run the application that is given in gdal download which is named as gdalread.cs.When I run it , it is asking for a dataset . Can any one let me know if i have to specify filename over here. Actually i want to read enc file which has s57 datset. So, I am confused if i need to specify filelname or s57 over here. Awaiting reply. With Regards, Neelima Emmani ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev

Re: [gdal-dev] DBF file associated with Raster
Another possibility is that the GDAL PAMDataset could store RAT in auxiliary xml files, so you can keep the raster data as it is. The problem is that you would need to convert the content of your DBF to the PAMDataset schema. Does it makes sense Even? Yes, I was also thinking to some sort of Raster Attribute Table, but didn't want to pronounce such a big word without more information ;-) If it is some kind of RAT, it might be possible to convert it to the PAM format, but as there's no tool to do that, that needs some scripting skills. And I'm not sure that many tools make actual use of GDAL RAT, so the usefulness might be limited. Depending on the intended usage, it might be sufficient to deal with the raster and the vector separately : for example, opening the DBF as an attribute table in QGIS and using the picking tool of QGIS to read the value of a pixel, and making the correlation manually. ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
Re: [gdal-dev] gdal dataset
Neelima, Perhaps I didn't understand your question. You said that it was asking for a dataset. How did it ask? What were the error messages you got? In your future queries, please include as much information as you can provide.

Re: [gdal-dev] gdal error
Hi when I try to invoke Gdal.AllRegister I get the below error: The type initializer for OSGeo.GDAL.GdalPINVOKE threw an exception. When i checked for a online solution, they said that it is looking for gdal_wrap.dll. Yes, my project does not contain any gdal_wrap.dll. First thing is that, when i try to create a interface with nmake /f makefile.vc interface. Things are fine.There was no error. Here I also have a question, How do i check if this step of inerface is successful. And then i went with next step C:\GDAL\swig\csharp nmake /f makefile.vc At this step, i am getting errors in gdal_wrap.cpp.It says at line 448 , it is unable to convert 'cplxmlnode *' to '_cplxmlnode *'. Can any one me in solving this. Secondly, in the mean time I tried to generate dlls from C#. And was successful in making gdal, osr ogr dlls for csharp. And then tried to run an application given by gdal i.e., gdalread.cs. It gave me error as said in the start of this mail message. If i am not clear, please let me know. Awaiting reply.

Re: [gdal-dev] Compile GDAL with HDF4 and Shapefile-Support (64bit)
Maybe I need an older version of the C#-GDAL-bindings in order to use the version included in FW-Tools ? Since the code for loading GDAL is quite simple and works with newer GDAL-versions (32 / 64 bit) that seems to be the most likely reason for me. Has anybody used (version 1.7 32bit / FW-Tools-)GDAL in C# (or another Visual Studio language) with raster- and vector-graphics at the same time ? Then it might be helpfull for me to know the version and source of the bindings used. :) -- View this message in context: http://osgeo-org.1560.n6.nabble.com/Compile-GDAL-with-HDF4-and-Shapefile-Support-64bit-tp4998275p5000403.html Sent from the GDAL - Dev mailing list archive at Nabble.com. ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
[gdal-dev] Can't delete feature from shapefile in python
Hello all,
I'm trying to delete a number of records from shapefile based on an
attribute. The strange thing that is happening is that feature count never
changes but if i make the same filter a second time the features are no
longer there. The code i'm using is below. I should be doing something
wrong for sure.
import os
from osgeo import ogr
path = 'C:\\datasets'
os.chdir(path)
shp = ogr.Open('locais.shp',1)
layer = shp.GetLayer(0)
print layer.GetFeatureCount()
layer.SetAttributeFilter('name ilike nacional%')
feat = layer.GetNextFeature()
while feat:
featId = feat.GetFID()
layer.DeleteFeature(featId)
feat = layer.GetNextFeature()
shp.Destroy()
Any suggestions? Thanks in advance.
Regards,
--
