use-spatial-reference

Primitive spatial reference vocabulary for RustUse.

use-spatial-reference provides small descriptive types for EPSG codes, spatial-reference identifiers, spatial-reference systems, and coordinate reference systems.

Non-goals

• EPSG registry fetching
• external-registry validation
• coordinate transformation
• deep CRS parsing

Example

use use_spatial_reference::{CoordinateReferenceSystem, EpsgCode, SpatialReferenceId};

# fn main() -> Result<(), Box<dyn std::error::Error>> {
let epsg = EpsgCode::new(4326)?;
let identifier = SpatialReferenceId::new("WGS84")?;
let crs = CoordinateReferenceSystem::from_epsg(epsg);

assert_eq!(epsg.to_string(), "EPSG:4326");
assert_eq!(identifier.as_str(), "WGS84");
assert_eq!(crs.to_string(), "EPSG:4326");
# Ok(())
# }
