New Course: QGIS Plugin Development with Python

QGIS plugins allow you to extend the QGIS toolset to fit your own specific needs, or to develop general purpose tools that solve common problems that others may be facing.  Although you can do quite a lot with Python in QGIS without developing a plugin (see Automating QGIS 3.xx with Python), plugins allow you to develop beautiful graphical user interfaces using PyQt5, and make your solutions easily available to other people.

New Course: PyQt5 From A-Z

PyQt5 is a Python package that allows you to develop graphical user interfaces in Python.  It is available on Windows, MacOS, and Linux  and the GUIs that you create will have the look and feel of your native operating system.  It is available under an open source license so you can get started with no cost to you. If you love the power of Python and all of the thousands of packages available for scientific and database applications, but wish you could provide your users with something other than a command line interface, PyQt5 is for you.

New Course: QField Quickstart

QField is an open-source Android based mobile data collection and/or viewing application that is tightly integrated with QGIS.

QGIS is used to set up the project using standard QGIS tools.

If the layers in your project are stored in a PostGIS database and a mobile data connection is available then changes made in QField are made directly to your database and visible in real-time to anyone that has a client to your database. This, in my view, is the mobile data collection killer app.

Deploying a PostGIS Database Parts 5 and 6 – Performance considerations

In these two videos I discuss performance considerations when choosing a hosting service for your PostGIS database, how to determine if you should invest in higher download speeds on the client side or better performance on the server side, and strategies for mitigating slow response times.
