[mapserver-users] On-the-fly field calculation in a GetFeatureInfo request

Hello Patrice,

I would prefer to save the data in a database using a view to create the
additional field (I haven't tried, but I think even spatialite is
possible as mapserver-deatasource?)

Another way would be to use scripting
- calculate the value with javascript within the template-html or
- use server-side processing within the template

Regards, Jörg
