Identification
Areas can be identified as a Travel feature when this area has the identification attribute. This is the first attribute in the described table of attributes for each Travel feature. They are also listed in the table above.
The identification attribute can be configured as a key of the Travel Distance Overlay. Keys indicate which attribute of constructions or features is used to represent specific geographical input parameters for the calculation. This can be of use when setting up a project or template which makes use of user-provided geodata.
