Python installation

First, you need to install Python because ProjPicker is written in Python. Since not many Python modules support 3.10 yet, we will use Python 3.9.7.

1. Download python-3.9.7-amd64.exe

2. Run the installer

3. Don’t install launcher for all users

4. Add Python 3.9 to PATH

5. Customize installation

6. Next

7. Customize install location

8. Change the installation path to C:\Python39

9. Install

10. Close

ProjPicker installation

Installing ProjPicker from its PyPI page is just one command line away.

1. Hit the Windows key

2. Type cmd and hit enter

3. In the command window, type pip install projpicker

4. Create a shortcut for C:\Python39\Scripts\projpicker.exe -g

pyproj installation

Install pyproj for coordinate matching and WKT.

1. From the same command window above, type pip install pyproj
