[gdal-dev] converting lines to linestrings

[Zoltan Szecsei]

Hi,
I'm not sure if this is the correct list to address this on, but ....

I have lots of files, each with a bunch of lines that start & stop on 
each others ends and I need to convert them into line strings, file by file.

Is there a command-line (batch) way I can do this?

They are currently in DGN (v8) format but I can convert them to SHP, 
MID/MIF or whatever.

What I'm looking to do is to create a batch pipeline that, file by 
file,  will take each line, and if either of its ends are within 0.5m of 
another line-end, then join them together to form one line string, then 
output that "snapped up" data to disk. (any format)

TIA,
Zoltan
