[Gdal-dev] problem with new pyton-gdal

[Fulko van Westrenen]

Hello,


I upgraded my system, and after the upgrade my Python program using 
gdal does not work anymore (what's new... :)

The old system was Debian Woody, with gdal 1.1.9 on Python 2.2. 
The new one is Debian Sarge/testing, with gdal 1.2+cvs.031111-1 on 
Python 2.3. I rolled the 1.1.9 package myself, the 1.2+cvs.031111-1 
is prebuild.

The error message is:
Traceback (most recent call last):
  File "./try37n.gtk.py", line 2887, in ?
    main()
  File "./try37n.gtk.py", line 2645, in main
    load_map()
  File "./try37n.gtk.py", line 569, in load_map
    bouyslat=load_objects(dataset,'BOYLAT')
  File "./try37n.gtk.py", line 511, in load_objects
    objects=dataset.GetLayerByName( name )
  File "/usr/lib/python2.3/site-packages/ogr.py", line 286, in GetLayerByName
    raise IndexError, 'No layer %s on datasource' % name 
IndexError: No layer BOYLAT on datasource

The offending code (snippets):
import osr
import ogr
...
(def load_map())
infile='./US5TX51M.000'
dataset = ogr.Open( infile )
bouyslat=load_objects(dataset,'BOYLAT')
...
(def load_objects())
objects=dataset.GetLayerByName( name )



GetLayerCount() reports 4 layers, there should be 57(?)

Downgrading is not an option. Does anyone have an idea what is wrong?

Thanks,

Fulko
