GQF-PYQGIS3

GQF for PYQGIS3

Introduction

This is a PYQGIS3 ported version of GQF, which now only works in the python console of QGIS3.

NOTE: tested with QGIS 3.4 and 3.6.2 under macOS 10.14.4.

Usage

within QGIS console

1. launch QGIS 3 and open its python console.
2. load the script RunGQF.py.
3. in RunGQF.py, set the path to GQF directory:

path_GQF = Path('your_path_to/GQF')

4. set other GQF configurations via the two namelist files:
   1. Parameters.nml: under GQF_Inputs_1, details refer to this page.
   2. DataSources.nml: under GQF_Inputs_1, details refer to this page.
5. execute RunGQF.py.

standalone Python environment without QGIS GUI

Note: this approach is only tested with the osgeo4mac distribution of QGIS3; but should similarly work with other configurations.

1. install osgeo4mac-brewed QGIS (for sure you need homebrew first):

brew tap osgeo/osgeo4mac
brew install osgeo-qgis

2. run QGIS3-Standalone-brew.py with the homebrew-ed python3:

python3 QGIS3-Standalone-brew.py

see QGIS3-Standalone-brew.py for configuration details.

Please report your issues if any configuration steps missed here.
