Hai Tamas,

May i know what the package for GDAL at nuget.org (GDAL, GDAL.Native and
GDAL.Plugins) cover? It can fully C# or  i still need ti use C++ then make
extension to C# so that it can use VS Wpf.

Thank you and best regards.

[gdal-dev] Question: build gdal2tiles.py as exe

2018-11-07 Thread К 
Hello! 
I'm trying to bulild gdal2tiles.py as standalone executable by using 
PyInstaller to use it as process from c# code (because gdal2tiles is'nt exist 
in bindings).
I tried with both Python 3.7.1 and Python 2.7.15, but the output binary is 
unable to run or lacks some functionality. For Python3 it runs OK, but throws 
an exception if i try to use "--processes" parameter.  For Python2 it can't run 
and says, that it's unable to find 'osgeo' package.
In both cases I used the following command line: pyinstaller 
D:\gdal\bin\gdal\python\scripts\gdal2tiles.py -D -p "D:\gdal\bin"
To build this version I used Gdal 2.3.2 stable daily release from GisInternals, 
build with x64 binaries and python on win10 x64.
It'd be great if you would advice me, how to build it as executable or a better 
way to use gdal2tiles in c# code (with no need to install python on target 
computer).
Thanks in advance for your reply!

In theory, yes, but in practice you can force the use of your current MSVC 
version and it happens to work just fine, by setting the following env 
variables

set DISTUTILS_USE_SDK=1
set MSSdk=1

Packages for GDAL have also been submitted to nuget.org  (GDAL, GDAL.Native
and GDAL.Plugins) which could be referenced in your Visual Studio project
easily.


Best regards,

Re: [gdal-dev] gdal_merge.py not executing or found

2018-11-07 Thread Dmitry Baryshnikov 

Hi Jeremy,

You can install QGIS with GDAL and python bindings using alternative 
installer by NextGIS (http://nextgis.com/nextgis-qgis/).


GDAL python bindings working, gdal_merge also included.

This is previous QGIS LTR release 2.18.25, but with fresh GDAL 2.3.2 and 
other libraries. This installation should not affect you current QGIS 
install, but I'm not sure about the opposite.


Best regards,
Dmitry

Thanks for the help Even.

Is there a simple way to check if the python bindings are installed? I
installed GDAL through the QGIS installer. I tried running gdal_merge.py
after downloading the file from github and have had no success.

You can always download the script from

(assuming that the GDAL Python bindings are installed)

[gdal-dev] gdal_merge.py not executing or found

2018-11-07 Thread Jeremy Salerno 
Hi All,

When I type gdal_merge.py into Terminal, the output is -bash:
gdal_merge.py: command not found.

I installed 3.4.0 Madeira [from this link] for macOS 10.13 (
https://www.qgis.org/en/site/forusers/download), which came with a gdal
installer.

I cannot even find the gdal_merge.py file in
/Library/Frameworks/GDAL.framework/Versions/Current/Programs/ or anywhere
else in the gdal framework directory. I looked to see if I could install
the .py file separately but can't find any installation options on the GDAL
website.


Thanks!

Jeremy

'proj' syntax is without quoting. And you only need +wktext for GDAL, not for 
PROJ utilities

It is likely you have an issue with GDAL linking also against your system 
PROJ. Has it been compiled --with-static-proj / --with-proj or not ? Check 
with ldd which libproj libgdal links against. You may need to adjust your 
LD_LIBRARY_PATH and potentially create a symbolic link from the new 
libproj.so. to the name of the old libproj.so.y so that GDAL sees one 
and one single libproj.
