Maybe it would make more sense to have:

PROMOTE_TO_MULTI - work for either polygon or linestring depending on 
what the first object is


or have two options like:

PROMOTE_POLY_TO_MULTI
PROMOTE_LINE_TO_MULTI

Or maybe, I'm totally missing something in the docs.


Sorry, forgot to add:

[gdal-dev] GDAL build without big tiff support

2017-05-15 Thread Dmitry Baryshnikov 

Hi,

it seem to me there is misprint here:

https://github.com/OSGeo/gdal/blob/trunk/gdal/frmts/gtiff/geotiff.cpp#L16195
instead of

> else if( nCompression == COMPRESSION_JPEG

should be

> else if( l_nCompression == COMPRESSION_JPEG


Without this fix I get such error in build without BIG TIFF Support: 
error C2597: illegal reference to non-static member 
'GTiffDataset::nCompression'

Best regards,

[gdal-dev] Help with getting gdal python module working

2017-05-15 Thread Candy, Liam 
Hi,

I've managed to get GDAL 2.1.3 to build with ECW 5.3 support on my 64-bit 
system. The last hurdle I'm struggling with is getting the python module to 
install and work. The lines in my nmake.opt file relating to python are;

!IFNDEF PYDIR
PYDIR = "... \AppData\Local\Programs\Python\Python36"
!ENDIF


HAVE_NUMPY=1

But the python module does not install.
I've tried going into the gdal-2.1.3\swig\python folder and installing manually 
with "python setup.py install", but when I try to import gdal in a script with 
"from osgeo import gdal" I get the error

Traceback (most recent call last):
  File 
"...\AppData\Local\Programs\Python\Python36\lib\site-packages\IPython\core\interactiveshell.py",
 line 2881, in run_code

  File

_mod = imp.load_module('_gdal', fp, pathname, description)
  File "...\Local\Programs\Python\Python36\Lib\imp.py", line 242, in load_module
return load_dynamic(name, filename, file)
  File "...\Local\Programs\Python\Python36\Lib\imp.py", line 342, in 
load_dynamic
return _load(spec)
ImportError: DLL load failed: The specified module could not be found.

Which I'm assuming is because the GDAL scripts can't find the relevant GDAL 
dlls.

Any idea on how to fix this ?

Best regards,
Liam.
