GDAL on Windows

Don't bother with OSGeo4W, it has no Bash and that feels totally crippled to me.

I am so fed up with Windows. Go this route: use DOCKER

Docker

1. Install Docker Desktop for Windows and tell it you want to use Linux containers. (You don't gain much by using Windows containers) 2. Start it. It will show up in the tray. It should now show up in Bash. Try 'docker version' and glory in it. 3. Pull the very best GDAL from the hub.docker.com and run it,

docker pull osgeo/gdal
winpty docker run -it --rm osgeo/gdal bash

Done. To mount a volume so you can access local data, I had to run in PowerShell (not Bash not Powershell ISE) for example

PS docker run -it --rm -v C:\Users\bwilson\source\repos\LiDAR\:/mnt osgeo/gdal bash
# cd /mnt
# ls
shows the right folder here
# echo in cans > foo
creates file called foo

ArcGIS Pro

2020-Mar-09 AGP version 2.5

AGP comes with conda. It comes with gdal 2.33 which is currently outdated.

Find the newest version.

conda search -c conda-forge gdal

Install a new environment.

conda create --name=gdal3 -c conda-forge gdal=3.0.4

Activate it, if you are a normal Windows user

activate gdal3

Activate if you are in a bash shell

$ source /c/Users/bwilson/AppData/Local/ESRI/conda/envs/gdal3/Lib/venv/scripts/common/activate
$ which python
/c/Program Files/ArcGIS/Pro/bin/Python/envs/arcgispro-py3/python

Try it

python
import osgeo.gdal

Build your own

ArcGIS 10 + Python + GDAL using OSGeo4W

OLD OLD OLD

2010-June-something

First install the installer. Get the Windows version for Python 2.6 and run it. See http://pypi.python.org/pypi/setuptools Add the C:\Python26\ArcGIS10.0\Scripts directory to your PATH. That allows your command shell to find and run easy_install.

Next install OSGeo4W for this. See http://trac.osgeo.org/osgeo4w/ Along with GDAL and PROJ4 which is what we're looking for right now, this installs lots of cool stuff like QGIS and uDig. (You can uncheck boxes if you are in a hurry or don't want the whole thing.)

You have to have gdal 1.7 installed before you install Python gdal. Turns out that's part of the OSGeo4W installation done in the previous section, so now all I have to do is figure out how to reference those files.

I can't figure that out yet.

Next step WOULD be to go install the Python packages using the installer. The easy_install GDAL" fails because it can't find the cpl_ports.h file that's installed with gdal in C:\OSGeo4W\

--

I got a little further along, I was able to get it to build and install and now it can't find _gdal.py I think possibly either it's not loading gdal17.dll or that's wrong and it really needs gdal171.dll

I downloaded source for gdal 171 (GDAL-1.7.1.tar.gz) and edited the file setup.cfg, adding the last two lines so it could find where OSGeo4W put things.

[egg_info] tag_build = tag_date = 0 tag_svn_revision = 0

[build_ext] gdal_config = ../../apps/gdal-config include_dirs = C:/OSGeo4W/include library_dirs = C:/OSGeo4W/lib

import osgeo.gdal gives

--- GOT IT (I've been making some notes here: http://wildsong.biz/index.php?title=Geoprocessing#Open_source)

Trying the Pypi

See http://pypi.python.org/pypi/GDAL/

Add "C:\Python26\ArcGIS10.0;C:\Python26\ArcGIS10.0\Scripts" to your PATH. Make sure it's ahead of OSGeo4W so that it does not find Python2.5 instead.

You have to have gdal 1.7 installed before you install Python gdal. Turns out that's part of the OSGeo4W installation done in the previous section, so now all I have to do is figure out how to reference those files.

I could not use "easy_install". I had to run build and install steps so that the compiler could find the right include and lib files.

I downloaded and unpacked the source file from the PyPi link above. Then I edited the config file! Here is mine:

[egg_info]
tag_build =
tag_date = 0
tag_svn_revision = 0

[build_ext]
gdal_config = ../../apps/gdal-config
include_dirs = C:/OSGeo4W/include
library_dirs = C:/OSGeo4W/lib

I added the last two lines, to tell it where I put the OSGeo4W files.

After that I was able to type this

python setup.py build
python setup.py install

and it WORKED. Then I was able to do this:

python
import osgeo.osr

To get the import to happen I had to set the environment, and there is a script to help me do that in c:\OSGeo4W\bin called gdal17.bat

In a cmd window I run that then I start python....

C:\OSGeo4W\bin>python
