# The Coordinate Reference System (CRS) required to interpret spatial coordinates

|

# | | | | | Range: Literal. A CRS is a reference system, but rico:referenceSystem covers |
|
||
# | | | | | any information representation framework, not just spatial coordinate systems.|
|

# | **DCTerms** | `dcterms:conformsTo` | dcterms.rdf:987-1010 | broad | "An established standard to which the described resource conforms." |
|
||
# | | | | | Range: Standard. A CRS is a kind of standard, but conformsTo covers any |
|
||
# | | | | | standard conformance — far broader than spatial reference systems. |
|
||
# | | | | | |
|
||
# | REMOVED: geosparql:hasSpatialResolution (geo.ttl:429-440) was listed as close, but it means |
|
||
# | "the level of detail / smallest distinguishable distance between coordinates" — about |
|
||
# | precision/granularity, NOT which CRS is used. Semantic mismatch. |
|
||
# | NOTE: GeoSPARQL has no dedicated CRS property. In practice, CRS is encoded within |
|
||
# | serialization formats (e.g., WKT SRID prefix) rather than as a standalone property. |
|
||
# | rec:coordinateSystem (Brick.ttl:32401-32404) exists but has no definition/comment — |
|
||
# | too underspecified for a verified mapping. |
