Liner referencing Linestring

Discussion created by blindsquare on Jul 18, 2011

I am a bit new to gis and I am struck. I have a network of rivers which is made up of small linestrings (polylines). In a different shapefile, i have locations of several stations on a river. I need to find distance along the river from each station till the end of river.

Problem is, i dont have one complete linestring of river. And there is no common attribute i can use to union or merge the linestrings. Also, some stations are on tributaries.

So bottom line, I need to make a large network of river including tributaries and perform liner referencing. But i dont know how. Any help is deeply appreciated. Please be as explanatory as possible.

Thanks in advance.
