How to implement a geospatial data pipeline for deep learning

After focusing on street-scene images, our deep learning framework is currently exploited in order to analyze aerial images and building footprints with semantic segmentation algorithms. We recently extend these last works by investigating an instance-segmentation use case. Context In parallel to the last FOSS4G conference at Dar es Salaam (Tanzania), WeRobotics recently organized the Open

QGIS Server 3 : OGC Certification work for WFS 1.1.0

QGIS Server is an open source OGC data server which uses QGIS engine as backend. It becomes really awesome because a simple desktop qgis project file can be rendered as web services with exactly the same rendering, and without any mapfile or xml coding by hand. QGIS Server provides a way to serve OGC web

“QGZ” – A new default project file format for QGIS

Last year we had the opportunity to implement ‘.QGZ’ as  anew variant of  the QGIS 3 project file format. This is simply a zipped container for the QGS xml file. We took benefit of that container to store the auxiliary storage database into it – only if users choose that optional format though. In classical

Pointcloud talk at the FOSS4G-fr conference

The Oslandia team was massively present at the great FOSS4G-fr conference that was held last week near Paris. One of the talks we gave was about Pointcloud, the PostgreSQL extension for storing point cloud data (a.k.a. LiDAR data), and LOPoCS, a lightweight server for streaming point clouds from PostgreSQL. If you want to know more about

Docker images for QGIS

With support from Orange we’ve created Docker images for QGIS. All the material for building and running these images is open-source and freely available on GitHub: https://github.com/Oslandia/docker-qgis. The docker-qgis repository includes two Docker images: qgis-build and qgis-exec. The qgis-build image includes all the libraries and tools necessary for building QGIS from source. Building QGIS requires installing
