Alexandre Neto

Geospatial Consultant

I work as geospatial consultant freelancer. I have more than 20 years of working experience. On my daily work, I help others with their GIS/Geospatial challenges and workflows, mainly using QGIS, GDAL, PostgreSQL/PostGIS, Python and other free and open source solutions.

I run regular online trainings on “Introduction to QGIS”, “Cartography and Datavis with QGIS”, “Relational Spatial Databases with QGIS and PostGIS”, and “Introduction to PyQGIS”.

I firmly believe that knowledge needs to be spread as much as possible. That is why I often share tips and tutorials on my blog, twitter, and Linkedin. I also answer questions on mailing lists, gis.stackexchange.com and the QGIS Community Telegram chat.

I try to be an active member of the QGIS community, where I help with documentation, testing, and Portuguese translations.

Create a PyQGIS Development Environment Using Conda and VScode

As a self-taught PyQGIS developer, one of my main hurdles has always been to prepare the development environment for PyQGIS. An environment that allow me to run PyQGIS scripts, helps me code faster by providing PyQGIS highlighting and autocompletion, enables me to debug my plugins and scripts as they run, etc… I have been a user (and even a… “cof cof”… maintainer) of the QGIS packages for conda provided by the conda-forge community.

Configure editing form widgets using PyQGIS

As I was preparing a QGIS Project to read a database structured according to the new rules and technical specifications for the Portuguese Cartography, I started to configure the editing forms for several layers, so that: Make some fields read-only, like for example an identifier field. Configure widgets better suited for each field, to help the user and avoid errors. For example, date-time files with a pop-up calendar, and value lists with dropdown selectors.

Using QGIS from conda-forge

QGIS recipes have been available on Conda-forge for a while, but now, that they work for the three main operating systems, installing QGIS from Conda is s starting to become a very reliable alternative to other QGIS distributions. Anyway, let’s rewind a bit… What is Conda? Conda is an open source package management system and environment management system that runs on Windows, macOS and Linux. Conda quickly installs, runs and updates packages and all their dependencies.
