Notes
The SHEF parser does not automatically support all the features that are described in the SHEF coding manual, and the following features will need to be configured manually:
- ID mapping to map the SHEF parameter codes to the correct FEWS parameter id's, location Id's etc. (see the SHEF coding manual)
- unit conversions, especially when the imported SHEF file contains imperial units instead of the SI units used by FEWS internally.
- Time zone conversion.
