Warning
titleRemoval of subsetting for EFAS

An issue has been identified with the EFAS sub-region extraction tool, whereby it serves data that is not correctly located on the river network. The sub-region extraction tool has therefore been removed from the EFAS CDS entries, and any area specified in cdsapi requests will return the entire domain .

Data previously downloaded using this tool should be disregarded.

For more information please see EFAS-Known Issues


Warning
titleCoordinates precision

When transforming from lat/lon (source coordinates) to projected LAEA (target coordinates), you need to consider that the number of decimal places of the source coordinates affects the target coordinates precision:

An interval of 0.001 degrees corresponds to about 100 metres in LAEA.

An interval of 0.00001 degrees corresponds to about 1 metre in LAEA.
