[Nuri BURHAN]

Hello.

I like postgis and spent lots time with postgis.

I haven't find a solition for my problem which is ;*how long does it take
 the busstop to the bus' GPS point?*

*result_linesting_geom=function (linestring_geom,point1_geom,point2_geom)*
*
*
***linestring_geom => bus path*
*point 1 => bus stop coordinat*
*point 2 => bus's GPS point coordinat*
*result_linesting_geom = > it is on **linestring_geom but between shortest
ponint 1 on **linestring_geom  and shortest point2  on **linestring_geom  *
*
*
*Any way thank you for your help.*
*
