mls_length
Geometric functions mls_length
- mls_length(mls_dataitem, valuesunit of coordinate system)
mls_length(multi-linestring dataitem, valuesUnit) calculates the total length for each arc value in a data item mls_dataitem.
The resulting values unit is configured as second argument. This gives an interpretation to the resulting values. It does not convert them. For example, if the coordinate system is in meters, then the resulting output are meter, but you should also configure it to be interpreted as meters. If you want kilometers as output, you'll have to manually convert it to km.
