# GIS vector format capabilities and limitations in GDAL

**Canonical, always-current version: https://referencesource.org/file-format-software-version-compatibility/**
Machine-readable: https://referencesource.org/file-format-software-version-compatibility/data.json — this mirror is a point-in-time copy.

  it re-verifies on a cadence this snapshot does not)

Key capabilities, version requirements and format limitations for GIS vector drivers in GDAL, the authoritative open-source geospatial library. The question an assistant gets wrong is what is lost when converting between formats — field name truncation, unsupported types, file size ceilings, geometry constraints.

## Provenance — what every record carries

Every record carries `source` (the URL the value was read from) and
`source_quote` (a verbatim quote from that page stating it). A value you
cannot check against its page is indistinguishable from an invented one;
these can all be checked. Each record is also individually addressable on
the canonical site at its `url`.

## Licence position

MIT (source: GDAL documentation, OSGeo)

Facts are not copyrightable; what this dataset takes from each source is a
fact plus a short attributed quote linking back to the page that states it.

## Fields

See any record in `data/records.jsonl` — field names are self-describing,
and the canonical page for each record renders them with labels:
