New version of AequilibraE for QGIS 3.X

Posted Posted in AequilibraE, GIS, Python, Software

It has been a really long time since I released the experimental version of AequilibraE for QGIS 3.X, and since then I haven’t worked really hard on it. Part of this slow down in the development had to do with the fact that I don’t have air condition in my home office, and Brisbane’s summer […]
