[mapserver-users] query mode, multiple selections

[Chris Kantarjiev]

Sure. The basic use case is:

User navigates to a particular, known, lat/lon as starting point; this can be by entering the known 
lat/lon values, or by navigation around cities.

User then selects one or more links and can inspect attributes associated with those links - in 
particular, link_id and direction. Initial selection could be by sweeping out an area, but should 
also provide a way of adding/removing specific links from the selection (control-select).

Did that makes sense?
