How much do we know?
A source is a published page or document behind a claim. The label measures what is documented, not whether a system is good or safe. Missing information does not prove that a safeguard is missing.

optional detailFull record and details
The interface and explanatory guides are translated. Record names, record descriptions, quotations, detailed editorial notes, and linked public documents stay in their published language so evidence is not silently changed.
What it does
Deep-learning models that classify French aerial-image pixels into land-cover types such as buildings, water, crops, and trees.
the story
Mapping every field, roof, tree, and water surface by hand would take years. CoSIA makes a first detailed pass from the air.
16 classes IGN describes sixteen land-cover classes at 20 centimetres per pixel
Facts to check
- 01
The output distinguishes buildings, water, vegetation, crops, and other surfaces.
- 02
IGN publishes the resulting CoSIA data openly.
- 03
The source explains that raw model output receives later processing and cross-checking.
If this affects someone
The map supports environmental and land-use analysis, including measurement of soil artificialisation.
IGN publishes technical documentation, class-level metrics, known error information, and describes further processing before final map products are used.
This is an open geographic dataset. Users can inspect the documentation and report mapping errors to IGN.
French aerial imagery, including infrared information, elevation data, and a large expert-annotated training area.

Based on ODAP public algorithms inventory. This page separates facts in the source from questions the source leaves open.
Plain-language text was checked against the linked sources. Older editorial records do not retain model or prompt logs, so this is explanation, never evidence.

The score orders work, not people.
Review priority rises for rights-sensitive uses, missing sources, unanswered accountability fields, and old evidence. Strong official documentation lowers it. The score is not a verdict on safety, fairness, or legality.
A missing field means the attached public sources did not answer it. Coverage is uneven, publication does not prove performance, and a certificate has a defined boundary.
