|
|
| 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. |
