At Geoalert, we employ Artificial Intelligence (AI) and Machine Learning (ML) to detect and extract real-world objects a.k.a. 'features' from satellite or aerial imagery.
You choose what type of features you want to extract, where and from which imagery, and Mapflow will do the work for you.
Currently we can detect:
- building footprints (optionally, with height)
- forest (optionally, with height)
- construction sites
- roads
More info about our AI models can be found here.
Mapflow supports various imagery sources types. You can upload your local GeoTIFF image, or use one of the tile services on the Web. By default, we use Mapbox Satellite, but you can specify a link to another imagery in XYZ, WMS, etc. You can also search the Mapflow imagery catalog and process a specific image.
The plugin can be found in the official QGIS plugin repository and can be installed by going to Plugins -> Manage and Install Plugins in QGIS, and then searching for 'Mapflow'. Make sure the 'all' tab is activated.
To learn how to use the plugin, please, follow our guide.
Automated tests run inside the official qgis/qgis:release-3_28 Docker
image — no host QGIS install needed, only Docker.
make test-functional # pure-logic tests
make test-qgis # tests that touch real QGIS objects
make test-ui # UI tests under xvfb (harness only — no tests yet)
make test # all three tiersTest layout, fixtures, and the policy for adding a test live in
tests/README.md.
Static analysis runs on the host (not in Docker) via the project venv:
pip install ruff pyright # once, into the venv
make lint # ruff check + pyrightruff (config in pyproject.toml) catches unused code and
real-bug patterns; pyright (config in pyrightconfig.json)
adds flow analysis ruff can't do, such as use-before-assignment and undefined
names. Pyright's type-completeness checks are muted until the codebase is
annotated. The rule set starts intentionally narrow — broaden it once the
baseline is clean.
Coverage scope. CI is pinned to Linux + QGIS 3.28 LTR. The
qgis/qgisDocker image is Linux-only and we do not run a CI matrix across operating systems or QGIS versions. Verify macOS, Windows, and non-LTR QGIS versions by manual smoke testing before release.
