Organizations that produce geographic data often have a geoportal to publish it, but no unified inventory of their entire data estate. datannur scans geospatial files and databases and catalogs them alongside tabular, statistical, and relational data, in a lightweight, generalist, sovereign catalog.
datannur supports the main vector formats — GeoJSON, Shapefile, GeoPackage, GeoParquet, GML, KML, and ESRI File Geodatabases (a multi-layer container whose every layer becomes a dataset) — as well as GeoTIFF rasters. These sources are scanned both locally and remotely (SFTP, S3, Azure, GCS), exactly like any other format in the catalog.
For each spatial dataset, datannur extracts the native coordinate reference system (for example EPSG:2056), the bounding box reprojected to WGS84, the geometry type and, for rasters, the spatial resolution. Attribute columns are described like any tabular data — schema, types, and statistics — and each raster band becomes a variable in its own right.
The spatial metadata is normalized and aligned with the domain standards (ISO 19115, STAC, DCAT). It can therefore be harvested by spatial data infrastructures such as INSPIRE or GeoCAT / geocat.ch, and reused in existing processing pipelines.
datannur describes and inventories your geographic data; it does not serve it. It provides no map rendering, no WMS / WFS / CSW services, and no spatial queries: it complements an existing GIS or geoportal rather than replacing it. That is exactly what makes it a relevant inventory for government bodies and organizations — often public-sector — that hold both geo and non-geo data and want to keep it under their own control.
