- Union in GIS: choosing between overlay, merge, unary union, and dissolve
Understanding the different types of unions in GIS Spatial union is one of the fundamental operations in geomatics. It allows you to combine multiple layers or entities to produce new geometries or enrich attributes. However, behind…
- Fuzzy logic and GIS (2/2): from transformation to aggregation of spatial data
In the first part of this series, we saw how fuzzy logic allows us to go beyond rigid thresholds by assigning each spatial entity a degree of membership between 0 and 1.We explored several membership functions,…
- Fuzzy logic and GIS (1/2): an alternative to all-or-nothing for geographic analysis
Modeling uncertainty and gradual transitions in QGIS using the FuzzyAttributes plugin. Not everything in geography is black and white. However, GIS tools often impose binary choices. What about transition zones? What about criteria that are partially…
- Exporting a QGIS layout to SVG: uses, limitations, and solutions
Exporting to SVG (Scalable Vector Graphics) from QGIS allows you to produce high-quality vector maps for printing or graphic editing in software such as Inkscape, Illustrator, or Affinity Designer. It is an interesting alternative to PDF,…
- Associating points with their municipality or zone: simple spatial joins with MMQGIS
When you have a layer of points (field surveys, geocoded addresses, incidents, observations, etc.) and a polygon layer (municipalities, sectors, zones), it is often useful to know which zone each point is located in. This is…
- Geocoding place names and finding an address from GPS coordinates with QGIS + MMQGIS
In a previous article, we saw how to geocode complete addresses with the MMQGIS plugin. Today, we will go further with two very practical use cases, still without coding: 1. Geocoding places based on their names…
- Work or train independently: create a portable QGIS environment
In our previous articles, we saw how to structure an efficient working environment in QGIS using bookmarks, template projects, the Layer Menu from Project plugin, and PyQGIS scripts. Today, we are taking an essential step forward:…
- Building a consistent, reusable QGIS environment: bookmarks, project templates and automation
In our previous article, we discovered how the Layer Menu from Project plugin enables you to quickly add layers to a project in progress. Today, we’re extending this logic to build a modular, reusable and professional…
- Save time with the “Layer Menu from Project” plugin in QGIS
When you regularly work on similar projects in QGIS – whether for spatial analysis, mapping or field monitoring – you may be wasting valuable time manually re-opening the same layers each time. The Layer Menu from…
- Portable version of QGis 3.44.0
You can download a portable version of QGis 3.44.0 from this link The compressed file is 1.2 GB. Once decompressed, it will occupy 2.91 GB on disk. What is a portable application? A portable application (or…
