Layer properties

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"]]' ...
