Helper functions for identifying and manipulating Coordinate Reference Systems.
(create-transform c1 c2)
Creates a proj4j transform between two projection systems.
c1 or c2 can be:
- integers (which will be interpreted as that EPSG)
- a string identifier for types EPSG:XXXX, ESRI:XXXX, WORLD:XXXX, NAD83:XXXX, or NAD27:XXXX
- proj4 string.
Check if input is a valid CRS name accepted by proj4j.
Accepted CRS names are in the forms:
EPSG:xxxx, ESRI:xxxx, NAD83:xxxx, NAD27:xxx, or WORLD:xxxx.
Converts EPSG string to SRID, if possible.
(includes? string substring)
Check if input appears to be a proj4 string
Convert an SRID integer to EPSG string.
(starts-with? string prefix)
