- Improving aerial image resolution with ESRGAN: when AI brings old photos back to life
Aerial images are a gold mine: old surveys, forest inventories, coastal monitoring, digitized cadastral maps, etc. But they often suffer from a major problem: low resolution. Blurring, pixelation, crushed textures, loss of detail… these are all…
- QGIS: AI comes to plugins – notable new features in December
New plugins, new practices: December illustrates the richness and diversity of the QGIS ecosystem. Between artificial intelligence, business productivity, and external data integration, these extensions open up concrete opportunities for geomatics professionals. December confirms a clear…
- Sentinel-2 with 1 m resolution: towards a more detailed analysis of coastal environments
In two previous articles, we explored how to convert standard Sentinel-2 images (10 m resolution) to a super-resolution 1 m version using the S2DR3 module, developed for coral research in Mauritius. This step provides an unprecedented…
- New QGIS plugins – November 2025
November brings a host of new developments to the QGIS extension ecosystem. Once again, the open source community demonstrates its dynamism with a variety of tools, ranging from basic mapping to advanced spatial analysis workflows, productivity,…
- When Deep Learning Dives Beneath the Surface: Mapping Corals with QGIS and PyTorch
Deep learning is revolutionizing satellite image analysis. Long reserved for large laboratories or proprietary software, it is now becoming available to the wider world thanks to PyTorch and QGIS. This article explores the principles of Deep…
- Study of corals with Sentinel-2 Deep Resolution 3 (S2DR3) using QGis and SCP
Following on from the article “How to increase the resolution of Sentinel 2 images from 10 to 1m” and “Using S2DR3 in Google Colab to study corals in Mauritius,” let’s take a look at how to…
- Using S2DR3 in Google Colab for coral research in Mauritius
Following on from the article “How to increase the resolution of Sentinel 2 images from 10 to 1m,” let’s look at a concrete example of how to use it. Work plan Step 1: Prepare the environment…
- How to increase the resolution of Sentinel 2 images from 10 to 1 meter
First of all, let’s give credit where credit is due! I discovered this technique thanks to Franz’s blog, which I invite you to explore if you speak Spanish. To process Sentinel 2 images, we will use…
- Fuzzy aggregation of two raster layers with FuzzyAttributes V2
After the two articles on converting a raster to fuzzy values: We will sees dans cet article comment agréger deux rasters flous en prenant en compte la subjectivité de l’utilisateur. Settings window In the FuzzyAttributes plugin…
- Converting a class raster to a fuzzy raster in QGIS
In some cases, the data is not continuous (altitude, slope, distance, etc.), but discrete, i.e., consisting of classes. Each pixel then corresponds to a category: a soil type, land use, risk level, etc. These “categorical” rasters…
