APEX

hi all,

i have a buss tracking/time tabling project

i have 3 types of data on my db

1 stations with (station_id lat long) of station
2 i have bus information, (buss_id, busname .....)
3 i have events table for that stores when the buss will pass a station (buss_id, station_id, datetime)

first things first:
i am using apex.oracle.com.
i have multiple tables with lat and long info on different columns.

am trying to do 2 things,

1) i have the locations of bus stations on a table, as station_id, lat, long
-i want to show them all on the map my using markers
-i want to be able to filter the shown


2) i want to show the route of a selected bus on the map date/time filtering would be nice

my idea is to create a report page(do filter the info on the page) then when some how forward the data i have to the map pages

thanks in advance :)
