# Date geospațiale naționale ale Republicii Moldova

> A curated, cloud-native selection from Moldova's national geoportal
> (geodata.gov.md), published as GeoParquet and PMTiles. Metadata is in
> Romanian, Russian, and English, with Romanian authoritative. Not an official
> publication of AGCC.

Root: https://data.source.coop/nlebovits/moldova-geodata/catalog.json

Read these before writing a query. The coordinate system and the curation
boundary both produce silently wrong answers if you assume the usual defaults.

## Start here

- [AGENTS.md](https://data.source.coop/nlebovits/moldova-geodata/AGENTS.md): join keys, worked queries, and the quirks that produce wrong answers rather than errors
- [README.md](https://data.source.coop/nlebovits/moldova-geodata/README.md): what the catalog holds, in three languages
- [catalog.json](https://data.source.coop/nlebovits/moldova-geodata/catalog.json): STAC root, with a child link per collection

## Two things that will cost you

**The CRS is metric, not degrees.** Every GeoParquet is MOLDREF99 / Moldova TM
(EPSG:4026), the source's own projected system, deliberately not reprojected.
`ST_Area` returns square metres directly. A spatial predicate written against a
WGS84 envelope matches nothing and raises no error. Transform explicitly when
joining to lat/lon data. The PMTiles are Web Mercator, because tiles must be.

**This is a selection, not a mirror.** The portal publishes more than this
catalog carries. A layer's absence here does not mean it is absent upstream.
Every source layer and its status is recorded in
https://github.com/nlebovits/moldova-geodata/blob/main/docs/layer-inventory.json

## Collections that hold no data

The eight `wms_*` collections list 147 layers the portal serves only as
images, because WFS or WCS is disabled for them. Their items carry links to the
live service and no downloadable asset. Do not write a query against them.

## The base map is one collection

`maps_base_map_2017` merges 90 source layers that differed only by feature
class. Filter on `layer_name` for a feature class, `source_layer` for the exact
WFS layer a row came from. Three assets, one per geometry type.

## Provenance

Extracted 2026-08-16 over workspace-scoped WFS 2.0.0. Every published layer was
verified against the server's own feature count.

The upstream server answers from several backends that disagree about which
layers exist, and it publishes no license text anywhere. Both are documented at
https://github.com/nlebovits/moldova-geodata/blob/main/docs/known-issues.md

## Optional

- [known-issues.md](https://github.com/nlebovits/moldova-geodata/blob/main/docs/known-issues.md): source faults, omissions, and upstream tool bugs
- [layer-union.json](https://github.com/nlebovits/moldova-geodata/blob/main/docs/layer-union.json): the union of repeated capability polls, with intermittent layers marked
- [terms.json](https://github.com/nlebovits/moldova-geodata/blob/main/docs/terms.json): the Romanian, Russian, and English term table, correctable by pull request
