To find the coordinate reference system, you can use crs() on the layer as shown in the following code:
crs = scf.crs()
The previous code assigns the coordinate reference system to the variable crs. From here, you can inspect it by getting the descriptions shown in the following code:
crs.description()
The previous code will return the output as follows:
'WGS 84'
For a well-known text (WKT) representation of the coordinate reference system, you can use the toWkt() method:
crs.toWkt()
This will return the results as follows:
'GEOGCS["WGS 84",DATUM["WGS_1984",SPHEROID["WGS 84",6378137,298.257223563,AUTHORITY["EPSG","7030"]],AUTHORITY["EPSG","6326"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["degree",0.0174532925199433,AUTHORITY["EPSG","9122"]],AUTHORITY["EPSG","4326"]]' ...
